Why a Properly Installed Alarm System Matters in WA

An alarm system is only as good as its design and installation. The same panel and the same sensors can produce a reliable, well-behaved system in one home and a frustrating, false-alarm-prone nuisance in another, and the difference is almost entirely down to how the system was planned, where the sensors were placed and how carefully it was commissioned. A home alarm that nuisance-trips gets switched off, and a switched-off alarm protects nothing. Getting the installation right is what turns a box of equipment into real peace of mind.

Western Australia regulates the security industry more tightly than many homeowners realise. Under the Security and Related Activities (Control) Act 1996 and its regulations, a person who installs, maintains, repairs or services security alarm equipment for gain must hold a security licence issued by WA Police. This sits apart from the electrical and building trades, which are licensed by other bodies, and it exists specifically so that the people fitting security equipment into homes are screened and accountable. Verifying that an installer holds a current WA Police security licence is a wise first step, and a reputable operator will provide their licence details without hesitation.

Alarm systems also have an electrical dimension. The alarm control panel itself runs on low voltage, typically twelve volts, and is powered through a plugpack or transformer. Where that transformer is hard-wired, or a new power point is needed to supply it, that part of the work is electrical installing work and must be carried out by a licensed electrical contractor under the Electricity (Licensing) Regulations 1991. A complete, compliant alarm installation in WA can therefore touch two separate licensing frameworks, and a quality installer understands and respects both.

Cost ranges for alarm installation are wide. A basic wired system covering the main entry points and living areas of a modest home can be supplied and installed for well under two thousand dollars, while a premium integrated system for a large home, with many zones, a 4G communicator, app control and camera integration, can run past eight thousand dollars. Most households choosing a solid monitored system land somewhere in the two to four thousand dollar band for the installation, with back-to-base monitoring charged separately as an ongoing subscription. Security often sits alongside other work, and where a home is also having CCTV and security cameras fitted, planning the two together produces a more coherent result than treating them as separate jobs.

Types of Alarm Systems

Residential alarm systems in Western Australia fall into a few broad categories, and the right choice depends on the home, the budget and how the household wants to interact with the system. The two foundational distinctions are wired versus wireless, and monitored versus unmonitored. Layered on top of those are smart systems with app control and integrated systems that bring alarms, cameras and automation together.

A wired alarm system connects the control panel to each sensor and siren by physical cable. It is the traditional approach, valued for its reliability and the absence of sensor batteries to replace. A wireless system instead uses radio communication between battery-powered sensors and the panel, which makes it far quicker and less invasive to install, particularly in a finished home where running cable through walls is difficult.

Monitoring is the other key axis. An unmonitored, or local, alarm sounds sirens and may send a notification to the owner, but no third party is alerted. A monitored alarm sends a signal to a professional monitoring centre when it is triggered, and the centre follows an agreed response procedure. Modern smart alarms add a smartphone app that lets the household arm, disarm and check the system remotely and receive notifications.

Integrated systems pull these threads together, combining intruder detection with cameras, smart locks and automation under one interface. The sections below work through each option in turn so the decision can be made on how the equipment actually behaves rather than on a brochure. Whatever the type, the security cabling and device work is regulated security work, just as fitted electrical equipment such as appliance installation is regulated electrical work, and using a licensed operator is not optional.

Wired Alarm Systems

A wired alarm system remains a strong choice, especially in a new build or a home undergoing renovation where cabling can be run before walls and ceilings are closed up. The control panel connects to each detection device and each siren by dedicated cable, usually concealed in wall cavities and roof spaces. Because the sensors draw power from the panel, there are no sensor batteries to monitor or replace, which many households appreciate over the long term.

The reliability case for wired systems is a real one. A hardwired connection is not subject to radio interference, signal range limits or the gradual decline of a sensor battery, so a well-installed wired system tends to be stable and predictable for many years. The trade-off is the installation effort. Concealing cable in a finished home means working through roof spaces, drilling discreet penetrations and routing carefully, and that takes time and skill.

Timing matters for wired systems in a renovation. Running security cable is far easier before finishing trades complete their work, so where a home is being reworked, the alarm cabling is best installed before, for example, new carpet laying closes off floor edges and before ceilings are sealed. Coordinating the security cabling with the rough-in stage of a renovation saves both cost and disruption, and an experienced installer will raise this sequencing if the project allows for it.

Wireless Alarm Systems

A wireless alarm system uses radio communication between the control panel and battery-powered sensors, which removes the need to run cable to every device. For an existing, finished home it is often the more practical choice, because installation is quicker, far less invasive and leaves no trail of patched walls. Modern wireless systems from established manufacturers are reliable and well suited to most residential situations.

The convenience comes with a maintenance consideration. Wireless sensors run on batteries that eventually need replacing, typically every few years depending on the device and how often it triggers. A good system reports a low battery to the panel and the app well before the sensor fails, so the replacement is planned rather than a surprise, but the household does need to act on those warnings. Signal range and the construction of the home can also affect wireless reliability, which is something the installer assesses during the site visit.

Wireless systems suit homes where running cable would be especially disruptive, such as double-brick construction or homes with limited roof access. They also adapt well to changing needs, since adding a sensor later is a simple matter of pairing a new device rather than running new cable. For homes that lack a practical way into the roof space, fitting a proper attic ladder and roof storage setup can make any future wired additions or servicing far easier, but a wireless system sidesteps much of that constraint from the outset.

The choice between wired and wireless is not a question of one being simply better. A new build leans wired, a finished home often leans wireless, and many systems today are hybrid, mixing wired devices where cable is easy with wireless devices where it is not. A licensed installer who assesses the specific home will recommend the mix that gives the most reliable coverage for the budget.

Monitored vs Unmonitored Alarms

Whether an alarm is monitored is one of the most important decisions in the whole project, because it determines what actually happens when the alarm is triggered. An unmonitored, or local, alarm sounds its sirens and, if it is a smart system, sends a notification to the homeowner's phone. Beyond that, nothing happens automatically. The response depends entirely on the owner or a neighbour hearing the siren or seeing the notification and acting on it.

A monitored alarm sends a signal to a professional monitoring centre the moment it is triggered. The centre, staffed around the clock, follows an agreed procedure: typically attempting to contact the homeowner and nominated contacts, and where appropriate arranging a patrol response or escalating to authorities according to the agreed plan. The value of monitoring is that it does not rely on someone being home, awake or within earshot.

There is a clear cost difference. An unmonitored system has no ongoing fee, while a monitored system carries a subscription, commonly in the order of three hundred to six hundred dollars a year depending on the service level and the response options included. For many households, particularly those who travel, work long hours or own a holiday home, the monitoring subscription is the part of the system that delivers the actual protection, while the equipment is simply what makes monitoring possible. The decision deserves an honest conversation with the installer about how the household lives and what response level genuinely suits it.

Back-to-Base Monitoring

Back-to-base monitoring is the term for an alarm system that reports to a remote monitoring centre, sometimes called a central station or control room. When a sensor triggers, the panel transmits a signal to the centre, which identifies the property, the zone and the type of event, and then works through the agreed response procedure. Monitoring centres operate continuously, every day of the year.

The Australian Standard AS/NZS 2201.2 covers monitoring centres and sets out grading and operational requirements, so that a centre handling alarm signals meets defined standards for staffing, resilience and procedure. When choosing a monitored service, it is reasonable to ask which monitoring centre the signals are sent to and how it is graded. A reputable installer will be transparent about this.

The response options attached to monitoring vary. The basic level is contact, where the centre phones the homeowner and nominated contacts. A higher level adds patrol response, where a security patrol is dispatched to inspect the property. Escalation to police follows agreed criteria. Each level has a cost, and the right choice depends on the property and the household. Monitoring contracts are also consumer contracts, so the term, the notice period and the conditions should be read carefully before signing, a point the consumer protection section covers further on.

Alarm System Components

Understanding the parts of an alarm system makes it easier to read a quote and judge whether it covers the home properly. The control panel is the brain of the system. It receives signals from every sensor, manages the arming state, triggers the sirens and, in a monitored system, communicates with the monitoring centre. Panels from manufacturers such as Bosch, Ness and Hills are widely used in WA residential systems and have long, well-supported track records.

The keypad, or in modern systems a touchscreen or app, is how the household interacts with the panel: arming and disarming the system, isolating zones and viewing status. Detection devices are the sensors that watch the home. The most common is the passive infrared motion detector, which senses the body heat of a person moving through a space. Reed switches, fitted to doors and windows, detect when an opening is breached. Other sensors include glass-break detectors and dual-technology detectors designed to reduce false alarms.

Sirens provide the audible and visible deterrent. An internal siren is loud enough to be unpleasant for an intruder and to alert anyone inside, while an external siren, usually paired with a strobe, draws attention from outside and signals to neighbours and passers-by that something is wrong. A backup battery inside the panel keeps the system running through a power failure, and in a monitored system the communication path, increasingly a 4G cellular module, carries signals to the monitoring centre. A quote should make clear what panel, how many and what type of sensors, what sirens and what communication method are included.

Sensor Placement and Coverage

Sensor placement is where an installer's skill shows most clearly. The goal is reliable coverage of the areas an intruder would have to pass through, without creating blind spots and without placing sensors where everyday household activity will trip them unnecessarily. Good placement is a design exercise, not a matter of bolting detectors to convenient walls.

Motion detectors are typically positioned to cover hallways, living areas and other internal spaces an intruder must cross to move through the home, often mounted in a corner to give the widest field of view. Entry points get particular attention, with reed switches on external doors and accessible windows so a breach is caught at the perimeter. The aim is layered coverage, catching an intrusion at the boundary and again inside.

Avoiding false alarms is just as important as achieving coverage. A motion detector aimed across a sunny window, near an air conditioning outlet that blows curtains, or in the path of a pet will trigger when nothing is wrong, and repeated false alarms erode trust in the system. Pet-tolerant detectors, careful aiming and thoughtful positioning all help. Where a home has features that move air or light, the placement has to account for them, which is one reason a competent installer asks about pets, heating and cooling, and how rooms are used before deciding where sensors go.

Placement also intersects with how the home is fitted out. A motion detector should have a clear view of the space, so positioning it where tall built-in wardrobes or shelving will block its field of view undermines the coverage. Door sensors need to suit the door type, and an installer fitting reed switches will plan around the specific doors in the home, including any sliding or specialty doors. Thinking through these details at the design stage produces a system that protects the home without crying wolf.

Security Licensing in Western Australia

The licensing of security work is the single most important regulatory point for a WA homeowner engaging an alarm installer. In Western Australia, the security industry is regulated under the Security and Related Activities (Control) Act 1996 and the associated regulations, and the licensing system is administered by WA Police rather than by a building or trade regulator. This is unusual compared with most home trades and is worth understanding.

Under that framework, a person who installs, maintains, repairs or services security alarm equipment as a business or as an employee of one must hold an appropriate security licence. The licensing process involves probity checks, which is the point of placing it with the police: it screens the people who will be entering homes and fitting the equipment that protects them. An installer working without the required licence is operating outside the law, and a homeowner using one has no assurance that any screening has taken place.

Verifying a licence is straightforward and worthwhile. A reputable installer provides their security licence details on request and is comfortable being checked. Resistance to providing licensing information is a clear signal to look elsewhere. Information on the security licensing system is published by WA Police, and homeowners should treat a current licence as a non-negotiable requirement, not a nice-to-have.

Electrical Work and Licensing

Although an alarm system runs on low voltage, the installation can still involve electrical work that falls under a separate licensing framework. The control panel is powered by a transformer or plugpack, and where that supply is hard-wired into the home's electrical system, or where a new power point must be installed to feed it, that work is electrical installing work governed by the Electricity (Licensing) Regulations 1991.

Electrical installing work in WA must be carried out by a licensed electrical contractor, with the Building and Energy division of the Department of Mines, Industry Regulation and Safety maintaining the licence register and overseeing the system. Many alarm installations use a simple plug-in power supply that needs only an existing power point and therefore no electrical work, but where hard-wiring or a new outlet is involved, the licensed electrical side of the job is not something to overlook.

This dual nature is why coordinating trades can be worthwhile. Where an alarm installation is happening alongside other electrical work in the home, such as an air conditioning installation or general electrical upgrades, a single coordinated visit can cover the electrical supply needs of several jobs at once. Official information on electrical licensing is published by DMIRS, and a homeowner is entitled to ask how the power supply for the alarm will be provided and who is licensed to do that part of the work.

AS/NZS 2201 Intruder Alarm Standards

The Australian and New Zealand Standard AS/NZS 2201 is the family of standards for intruder alarm systems, and a competent installer designs and installs to the relevant parts. AS/NZS 2201.1 covers the design, installation, commissioning and maintenance of systems at the client's premises. AS/NZS 2201.2 covers monitoring centres. AS/NZS 2201.3 deals with detection devices, and AS/NZS 2201.5 addresses alarm transmission systems.

For a homeowner, the standards matter because they define what a properly designed and installed system looks like: appropriate detection coverage, correct device selection, sound commissioning and a sensible maintenance basis. An installer who works to AS/NZS 2201 is following an agreed benchmark rather than improvising, and that shows up in a system that performs reliably and behaves predictably.

Some homeowners need a system that meets a specific standard or grade, for example because an insurer or a particular circumstance requires it. In that case the requirement should be stated clearly to the installer at the quoting stage so the system is designed to meet it. Standards are periodically reviewed and updated, and the current versions are published by Standards Australia. Even where no specific grade is mandated, asking an installer whether they design to AS/NZS 2201 is a fair and revealing question.

The NBN and Alarm Communication

One issue catches out a great many WA households with older monitored alarms, and it is worth a dedicated explanation. For decades, monitored alarm panels reported to the monitoring centre by dialling out over the copper telephone line. As the National Broadband Network was rolled out across Western Australia and the old copper telephone service was progressively switched off, those dial-out alarm panels lost their reliable path to the monitoring centre.

The result was that many homeowners discovered, often without realising it at first, that their monitored alarm was no longer actually being monitored. The panel still armed and the sirens still sounded, so the system seemed to work, but the link back to the monitoring centre had quietly stopped functioning. An alarm that cannot reach its monitoring centre is, in effect, an unmonitored alarm regardless of what the household is paying for.

The fix is a communication upgrade. A 4G cellular communicator module gives the panel a dependable mobile path to the monitoring centre that does not rely on a fixed phone line, and an internet-based path can serve a similar role. For a household with an older monitored system, having the communication path checked, and a 4G communicator fitted where needed, restores genuine monitoring at a modest cost. If you have a monitored alarm installed before the NBN reached your area and you have never had it checked since, this is worth investigating.

Smart Alarms and App Control

Modern alarm systems are increasingly smart, meaning they connect to a smartphone app that lets the household interact with the system from anywhere. The app typically allows the system to be armed and disarmed remotely, shows the current status, lists recent events and sends a push notification when the alarm is triggered or when a particular event occurs.

The practical value of app control is real. A household member who has left home unsure whether the alarm was set can check and arm it from their phone. A notification arrives the moment something happens, rather than depending on a siren being heard. Temporary access can be managed, and the event history makes it easy to see what has been happening at the property.

A smart alarm and a monitored alarm are not the same thing, and the distinction is worth keeping clear. App notifications go to the homeowner, while monitoring sends signals to a staffed centre that follows a response procedure. Many households choose both, so that they get the immediacy of app notifications and the reliability of professional monitoring. A licensed installer can explain which panels support which features and design a system that gives the household the control and the response level it actually wants.

Integration with Cameras and Home Automation

An alarm system increasingly forms one part of a broader home security and automation picture. Integrated systems bring intruder detection together with cameras, smart locks, lighting and other automation, managed through a single app or interface. The appeal is a coherent setup where the components work together rather than as a collection of unrelated gadgets.

Cameras are the most common companion to an alarm. Where the alarm tells the household that something has been detected, cameras let them see what it is, which helps distinguish a genuine intrusion from a false trigger and provides a record. Designing the alarm and the camera coverage together produces better results than bolting one onto the other later, and a household considering both should look at CCTV and security camera installation as part of the same planning exercise.

Integration can extend further, into lighting and presence simulation that makes an unoccupied home look lived in, and into smart locks and access control. Some households also coordinate security with window furnishings, since automated blinds and curtains can contribute to that occupied appearance and to privacy. The right level of integration depends on the household, and a licensed installer can advise on what actually adds value rather than simply adding complexity and cost.

Pre-Installation Assessment

A site assessment before installation is where a well-designed system begins. The installer walks the property inside and out, identifies the entry points, considers how an intruder would approach and move through the home, and works out where detection coverage is needed. The assessment also covers the practical questions: where the panel and keypad will sit, how cabling can be routed for a wired system, and where the external siren is best placed.

The assessment is also when the household's circumstances are taken into account. Pets, the way rooms are used, heating and cooling that moves air, and the daily routine all influence sensor selection and placement, so a good installer asks about them. For a monitored system, the assessment covers the communication path and confirms that a reliable route to the monitoring centre is available.

For wired systems, and any work that involves drilling or running cable through walls and ceilings, the age of the home matters. Properties built before the late 1980s, and many into the early 1990s, may contain asbestos in wall sheeting, eaves and ceilings, and disturbing it without checking is a genuine hazard. A thorough assessment of an older home flags this, and arranging asbestos testing and inspection before any cutting begins is the responsible course, covered further in the section below.

The Installation Process

A typical alarm installation follows a logical sequence. The installer confirms the agreed design with the homeowner, then mounts the control panel and keypad in their planned positions. Detection devices are installed at the locations set out in the design, sirens are fitted internally and externally, and for a wired system the cabling is run, concealed and connected. For a wireless system the sensors are paired with the panel and signal strength is checked.

The power supply and any communication module are connected, with any hard-wired electrical work handled by a licensed electrician. The panel is programmed with the zones, the arming options and, for a monitored system, the monitoring centre details and response plan. The installer then works through commissioning, testing every sensor and siren and confirming the system behaves as designed.

For a wired system in a renovation, sequencing with other trades matters. Concealed cabling is far easier before finishing work, so security cabling is best completed before, for example, new carpet installation closes off floor edges. Where the home is also having other security or low-voltage work done, coordinating the trades reduces both cost and disruption. A tidy installation, with cable concealed and devices neatly mounted, is a sign of a careful operator.

Older Homes and Asbestos

Western Australia has a serious history with asbestos, and any alarm installation that involves cutting or drilling into an older home must account for it. Homes built before the late 1980s, and many into the early 1990s, may contain asbestos-containing materials in wall sheeting, eaves, ceilings and other elements. Wired alarm work routinely involves drilling for sensors and reed switches and running cable through walls and roof spaces, all of which can disturb asbestos if it is present and unidentified.

Disturbing asbestos releases fibres that are hazardous to breathe, so the safe approach in an older home is to identify materials before any cutting begins. Where the age of the property and the visible materials suggest asbestos may be present, arranging asbestos testing and inspection ahead of the installation is the responsible step, and it is far better to know in advance than to discover the problem once a drill has already passed through a sheet.

Where asbestos is confirmed in the path of the work, it must be handled correctly. Licensed asbestos removal deals with asbestos-containing materials properly rather than treating them as general waste, in line with WA health and worksafe requirements. A wireless alarm system, which needs far less drilling than a wired one, can sometimes be the more practical choice in an older home for exactly this reason. A reputable installer will raise the asbestos question rather than cutting through suspect material, and a homeowner of an older property should welcome that caution.

Alarm Systems and Smoke Alarms

It is worth being clear about the difference between an intruder alarm system and a smoke alarm, because the two are sometimes confused. An intruder alarm system, the subject of this guide, detects unauthorised entry. A smoke alarm detects the products of a fire and is a separate, legally mandated safety device.

In Western Australia, working smoke alarms are a legal requirement for residential properties, governed by building and residential requirements rather than by security legislation, and they must be installed and maintained to those requirements. Some integrated security systems can include smoke detection that reports to the monitoring centre, which adds a useful layer, but that does not replace the separate obligation to have compliant smoke alarms.

Homeowners should treat the two as distinct and make sure both are properly addressed. Guidance on smoke alarms and fire safety in WA homes is published by the Department of Fire and Emergency Services, and homeowners can find that information through DFES. When commissioning an alarm system, it is a good moment to also confirm that the home's smoke alarms are present, working and compliant.

Testing, Commissioning and Handover

Commissioning is the step that confirms an alarm system actually works as designed, and it should never be rushed. The installer tests every detection device, walking the property to confirm each motion detector responds across its intended coverage and each door and window sensor triggers correctly. The sirens are tested, the backup battery is checked, and for a monitored system a test signal is sent to the monitoring centre to confirm the communication path is sound.

The handover is just as important as the technical commissioning. The installer should show the household how to arm and disarm the system, how to isolate a zone, how to use the app if one is fitted, and what to do in common situations such as a false trigger or a low-battery warning. A system the household does not understand will be used poorly or not at all.

The handover should also include the paperwork: the system documentation, the zone list, the monitoring details and response plan if monitored, the warranty information and any electrical completion documentation for hard-wired work. Keeping these records together is worthwhile, as they support warranty claims, future servicing and any insurance interaction. An installer who switches the system on and leaves without a proper walkthrough and the documentation has not finished the job.

Maintenance and Reducing False Alarms

An alarm system benefits from modest, regular attention. For a wireless system, the main task is responding to low-battery warnings and replacing sensor batteries before they fail, which a well-designed system flags well in advance. For all systems, the backup battery in the control panel has a finite life and eventually needs replacing so the system rides through a power failure. Periodic testing, walking the property to confirm every sensor still responds, keeps small faults from going unnoticed.

False alarms deserve particular attention because they undermine confidence in the system and, for a monitored system, can incur response costs. Most false alarms trace to a handful of causes: a sensor disturbed by a pet, by air movement from a heating or cooling outlet, or by sunlight; a sensor knocked out of alignment; an insect inside a detector; or simple user error in arming the system. A periodic service can re-aim sensors, clean detectors and check the system over.

Maintenance also matters for rental properties and at change of tenancy. When a tenancy ends, confirming the alarm system works, the codes are reset and the documentation is in order sits naturally alongside the broader handover, and it is easy to fold into the same period as professional bond cleaning. A well-maintained alarm that the household trusts and uses correctly is far more valuable than a more expensive system that nuisance-trips and gets switched off.

What to Look Out For

The first thing to check is licensing. A security installer in WA must hold a current security licence issued by WA Police under the Security and Related Activities (Control) Act 1996, and any hard-wired electrical work must be done by a licensed electrical contractor. A reputable operator provides these details readily. Resistance to providing licensing information is a clear warning sign, and a homeowner should not proceed without verifying it.

A quote that sits well below the others for the same system warrants scrutiny rather than instant acceptance. A low quote often reflects fewer sensors than the home actually needs, cheaper equipment, an undisclosed exclusion, or a monitoring contract with terms that are not obvious upfront. Direct comparison requires consistent specifications: the same panel grade, the same number and type of sensors, the same sirens and communication method, so the quotes describe the same level of protection.

Monitoring contracts deserve careful reading. The subscription cost, the contract term, the notice period required to cancel, and exactly what response is included should all be clear before signing. Be wary of an installation offered cheaply or free that is tied to a long, expensive monitoring contract, because the real cost is in the contract, not the equipment. The monitoring arrangement is a consumer contract and should be treated as one.

Watch for verbal promises that never appear in writing, and be cautious of high-pressure sales tactics, particularly door-to-door approaches that push for an immediate decision. The system design, the equipment, the price, the monitoring terms and the warranty should all be documented before any work or any contract is committed to. A professional operator is comfortable giving a homeowner time to consider and compare.

How to Get Useful Quotes

Three written quotes against a consistent brief give a meaningful picture of the market. The brief should describe the home, its size and approximate age, the entry points and areas of concern, whether monitoring is wanted, and whether app control or camera integration is part of the plan. Without consistent information, quotes describe different systems and the cheapest figure can be the least protection.

A site visit is essential before treating a quote as firm. A security system has to be designed around the specific home, so an installer needs to walk the property, assess the entry points and coverage, consider cabling routes and confirm a reliable communication path for monitoring. A quote given over the phone without a site visit is an estimate that cannot reflect the home's real layout.

Verify each quoting installer's security licence and, where relevant, the electrical licensing, confirm insurance is current, and where possible speak to previous customers about the quality of the installation and how any issues were handled. Compare the quotes line by line: the panel, the sensor count and types, the sirens, the communication method, the monitoring terms, the commissioning and handover, and the warranty on both equipment and workmanship.

Be cautious about payment and contracts. A modest deposit followed by payment on completion is normal for the installation, while a large upfront payment, or an installation locked to a long monitoring contract, deserves questioning. Posting a clear job description through The Quote Yard is a quick way to reach several licensed WA security installers at once and gather genuinely comparable quotes.

Insurance, Strata and Warranty

Home insurance and alarm systems interact in a few ways worth understanding. Some insurers take a monitored alarm into account when assessing a policy, and some policies expect certain security measures for particular properties or contents. The detail varies between insurers and policies, so a homeowner installing a system partly for insurance reasons should check directly with their insurer what is recognised and what, if anything, is required, rather than assuming.

Strata properties add a layer. In many schemes the alarm system serving an individual lot is the lot owner's responsibility, while common-area security and the building fabric are common property managed by the owners corporation. Installing sensors, running cabling or fitting an external siren on common property may need the owners corporation's approval, and the Strata Titles Act 1985 provides the framework. Lot owners should check the by-laws and obtain any approval needed before commissioning an installation.

Warranties come in two parts. The equipment carries a manufacturer warranty, with terms varying by brand and component, and panels and sensors from established manufacturers such as Bosch, Ness and Hills are generally well supported. The installer separately provides a workmanship warranty covering the quality of the installation itself. Statutory guarantees under the Australian Consumer Law also apply alongside any express warranty, covering both the goods and the service. Information on consumer rights, including in relation to monitoring contracts, is available from Consumer Protection WA and the ACCC.
