Alarm and Security System Repairs in Perth
Rest-A-Sured handles alarm repairs across Perth and regional WA, on alarm, CCTV and access systems, whether we installed them or another provider did. You do not need to have bought the system from us to book a repair.
Most alarm repairs come down to a handful of recurring faults, and all of them are fixable. A technician tests the whole system rather than just the part that is playing up, finds the cause, and tells you plainly what was fixed and what is worth upgrading.
We are WA owned and operated, based in Wangara, servicing Perth and regional WA since 1998, and we hold security licence 09458. For scheduled servicing, see alarm service and maintenance.
Common Alarm Faults We Repair
False alarms
Usually ageing or dusty sensors, insects, or incorrect zone settings. Frustrating for you, and costly if they trigger a monitored response.
Beeping and battery faults
A backup battery at the end of its life is the single most common cause of a system beeping, dropping out during a power cut, or reporting a fault.
Old or failing panels
Panels that are slow, unreliable, or no longer supported by the manufacturer.
Lost monitoring connection
Older alarms that dialled out over a phone line or the retired 3G network can no longer reach monitoring and need a communications upgrade.
If your alarm is beeping, showing a fault, or simply not giving you confidence, a repair visit gets to the cause rather than guessing.
Why Is My Alarm Beeping?
A constant or intermittent beep is almost always a fault warning. The most common cause is a backup battery that has reached the end of its life. It can also signal a communications or power issue. A repair visit identifies the exact cause rather than just silencing it.

Alarm Repairs Perth FAQs
Do you repair alarms you did not install?
Yes. We repair, service and upgrade systems installed by other providers, and can take over monitoring on most existing alarms.
Why does my alarm keep beeping?
A constant or intermittent beep is almost always a fault warning, most often a backup battery at the end of its life. It can also signal a communications or power issue.
What causes false alarms?
Usually ageing or dusty sensors, insects, or incorrect zone settings. We find the cause so the alarm stops triggering without reason.
My alarm used a phone line or 3G. Is that a problem?
It can be. Alarms that relied on a landline or the retired 3G network may no longer reach their monitoring station. We can upgrade the communications without replacing the whole system where possible.
Do you repair CCTV and access control as well?
Yes. We handle repairs and servicing on alarm, CCTV and access systems across Perth and regional WA.
Do you do alarm repairs outside the Perth metro area?
Yes. We service Perth metro plus rural and regional WA, including areas many city-based installers will not travel to.
