Commercial Alarm Systems for Perth Businesses
Rest-A-Sured Security installs, services, repairs and monitors commercial alarm systems across Perth and regional WA, for warehouses and industrial sites, retail and hospitality, offices, strata-commercial buildings, construction sites and petrol stations. We are WA owned and operated, based in Wangara, in the security industry since 1998, and we hold security licence 09458.
This page is about business alarms. For an alarm at home, see burglar alarm systems Perth. If you need cameras, access control and monitoring across a whole site, see commercial security systems.
A business alarm is a different job from a house. Sites are bigger, they have more entry points, they are occupied at irregular hours, and a false alarm costs somebody a call-out at 2am. Our work is mostly commercial, so the alarms we put in are zoned and scheduled around how the site actually runs.
What a Commercial Alarm System Includes
Every commercial alarm we install is specified to the site rather than sold as a package. A typical system includes:
Zoned Detection
Motion detectors, door and roller door contacts, glass-break and tamper detection, zoned so a warehouse, its office and its yard report separately.
Duress & Hold-Up
Duress and hold-up buttons for retail, hospitality, fuel sites and anywhere staff handle cash.
Schedules & Reporting
Scheduled arming and disarming, event alerts, and open and close reports showing when the site was armed and by which code.
Plenty of business alarm jobs are on sites that already have a panel. Whether it went in last month or twenty years ago, we can usually work with what is there rather than starting again, and we will tell you what is worth keeping. See alarm service, maintenance and upgrades.
Zoning a Business Alarm Around How the Site Runs
An all-or-nothing alarm across a whole building usually ends up switched off, because working around it is easier than using it. Splitting the site into areas that keep their own hours is what makes a commercial alarm get used properly.
Areas that arm separately
A warehouse with an attached office is a good example. One site we monitor runs 24 zones across two areas, with access set so a person can arm and disarm the warehouse only, the office only, or both, depending on what they are there to do.
Larger and multi-tenant sites
The larger shopping centres we monitor run 250 zones or more, with nine or more separate areas that arm at different times and are monitored separately, all on one system. Retail tenancies, management offices, loading areas and cleaning crews all keep different hours, and each area has to arm without disturbing the rest.
After-hours schedules
Arming schedules let the system tell the difference between a late shift and an intrusion, instead of calling you every time somebody works back.
Wired or wireless
Hardwired detectors suit new fit-outs and buildings with easy cable runs; wireless detectors suit finished buildings where running cable is hard. Many sites end up with a mix, and we install both.
Commercial Alarm Installation Perth: How It Works
Site Assessment
We walk the premises with you and map the entry points, existing wiring and any current alarm or CCTV equipment.
Written Quote
A written proposal covering equipment, zones and scope of works, so there are no surprises on install day.
Installation
Our technicians carry out the install, working around trading hours where required so the business keeps operating.
Handover
We walk your team through the system, set up user codes and monitoring settings, and test it before we leave site.
Ongoing Support
Service checks, repairs and upgrades as the business changes, from the same team that installed it.
Business Alarms by Site Type
Warehouses & Industrial Sites
Perimeter and yard coverage, roller door and dock monitoring, and zoning that separates the office from the warehouse floor so late shifts do not trip the alarm.
Retail & Hospitality
Duress and hold-up alarms for staff, with the public areas, the till and the back of house zoned separately. Cafes, restaurants and bars add late closes and cash on site, so arming schedules matter.
Offices
Alarms that arm and disarm with the working day, usually tied to access control so an alarm event can be matched to who badged in.
Strata-Commercial & Multi-Tenant Buildings
Each tenancy able to arm and disarm without affecting the others, with the building zoned so each one reports separately. See our strata security systems.
Construction Sites
Alarms for active building sites alongside CCTV, where plant, copper and materials are the target and the site changes as the build progresses. See construction site security.
Petrol Stations & Fuel Sites
Long trading hours with cash and stock on site, so alarms with duress buttons for staff, alongside CCTV over the forecourt and shop.
24/7 Monitoring for Commercial Alarms
An alarm that only sounds a siren relies on somebody nearby doing something about it. A monitored business alarm sends every signal to a control room staffed 24 hours a day.
Our alarm monitoring runs through one of the largest independently owned grade 1 monitoring stations in WA. Signals go over the GPRS and GSM mobile networks rather than a phone line, and a triggered alarm is assessed and acted on within 90 seconds, then escalated through your contact list, or to a guard response where you have arranged one.
Open and close reporting. You see when the site was armed and disarmed, and by which code. For a lot of business owners this is the feature they end up using most.
Escalation lists. The control room works through the right people in the right order, rather than ringing one number and giving up.
Integration with CCTV and Access Control
A commercial alarm rarely sits on its own. Tied to commercial CCTV, the operator can check the cameras covering a zone when it trips and confirm what actually caused it before responding. That is the single biggest reduction in false call-outs available to a commercial site.
Tied to access control, an alarm event can be matched to who badged in. If you already run CCTV or access control with another provider, we can usually bring the alarm onto monitoring without disturbing the rest of it.
Commercial Alarm Servicing and Maintenance
A commercial alarm is only as reliable as its upkeep. A service visit covers the panel and keypad, every sensor and zone, backup power, the siren and the communication path back to the monitoring station.
The most common fault we find is the simplest: a backup battery past its life, so the panel drops out the moment mains power does. As a general rule an alarm benefits from a service check at least once a year, and sooner if it is monitored, protects a business or is more than a few years old.
Full detail on what a service includes is on our alarm service, maintenance and repairs page.
Commercial Alarm Repairs and Faults
Nuisance triggers, dead zones, panels that have stopped reporting, and systems left behind by an installer who is no longer around. We repair alarm systems from any installer, so you do not need to have bought the system from us.
Older alarms that dialled out over a phone line or the retired 3G network may no longer reach their monitoring station. They usually need a communications upgrade, not a new system.
Taking Over an Existing Business Alarm
If your alarm was installed by another company, or came with a property you have taken on, you are not locked in. We can take over the servicing and connect your existing alarm to our grade 1 monitoring station, and you can move an existing monitored alarm across to us without replacing your panel.
We assess what you have, upgrade the communications or components where needed, and bring it across.
What Affects the Cost of a Commercial Alarm
The cost of a commercial alarm system in Perth comes down to the size of the site, how many areas and zones it needs, the number and type of detectors, whether it is wired or wireless, duress buttons, integration with CCTV or access control, and whether it is monitored.
We provide free, no-obligation quotes after a site assessment, in writing, so you know the scope and price before any work starts.
Commercial or Home Alarm: What Is the Difference?
Scale and control. A commercial system covers more doors, areas and people, so it needs zones that match the site, scheduled arming, open and close reporting, and links between alarms, CCTV and access control. A home system is simpler and usually run from one app.
If you are securing a house rather than a business, our burglar alarm systems page covers home alarms.

Choosing a Commercial Alarm Company in Perth
Rest-A-Sured Security has installed, upgraded and maintained security systems across WA for more than 28 years. We are WA owned and operated, we work from Wangara, and we cover the Perth metro area and regional WA, including sites some competitors will not travel to.
If you are comparing commercial alarm companies in Perth, the things worth asking are who actually does the install, whether they walk the site before quoting, whether they can service and repair the system afterwards, and who answers the alarm at 2am.
We are a security licence holder (09458) doing our own installs and our own maintenance, and we offer a 2-year warranty on installations. Our alarms are monitored through one of the largest independently owned grade 1 monitoring stations in WA, and because we also install CCTV and access control, the alarm can be one part of a joined-up site.

It can be. Alarms that relied on a landline or the retired 3G network may no longer reach their monitoring station. We can usually upgrade the communications without replacing the whole system.

Yes. Duress and hold-up buttons suit retail, hospitality, fuel sites and anywhere staff handle cash.

Yes. We cover Perth metro plus rural and regional WA, including locations competitors often will not travel to. See our regional installations.
