Description
The fire extinguisher anti-tamper alarm triggers a loud sounder if the extinguisher is removed from its bracket without authorisation — deterring theft and ensuring that any unauthorised removal is immediately detected. A 9VDC battery-powered unit with a deactivation cable: when installed, a cable connects the alarm to the extinguisher; pulling the extinguisher away breaks the connection and triggers the 100dB+ piezo sounder. Fast to install, compact design, and UV-stabilised polycarbonate housing suitable for indoor and outdoor locations.
Particularly useful in publicly accessible locations, high-theft areas, construction sites, and any location where extinguisher theft or tampering has previously been an issue.

Frequently Asked Questions
Where Anti-Tamper Alarms Are Used
- Public areas, lobbies, and retail premises where extinguisher theft is a risk
- Construction sites and temporary installations
- Schools, hospitals, and other public buildings
- Car parks and outdoor locations with limited supervision
- Any location where previous extinguisher theft or tampering has occurred
- Industrial sites requiring confirmation that extinguishers haven’t been moved from their designated positions
Installation
Mount the alarm unit to the wall near the extinguisher bracket using the provided fixings. Connect the deactivation cable between the alarm unit and the extinguisher. When the extinguisher is removed without first releasing the deactivation cable, the circuit breaks and the sounder activates. To remove the extinguisher legitimately (for servicing or use), release the cable first. The alarm does not replace the extinguisher bracket — both are required.
How loud is the alarm sounder?
The sounder is described by Flamestop as “loud ear piercing” — sufficient to alert building occupants and staff in the immediate area of an unauthorised extinguisher removal. The alarm is designed to deter casual theft and draw attention to the removal event, not to function as a monitored security system. It will not send a signal to a monitoring centre — the purpose is local deterrence and detection only. For high-security environments requiring monitored alarms, integrate extinguisher protection into your building’s security system.
Does the alarm work if the battery dies?
No — if the 9VDC battery is depleted, the alarm will not function. Check and replace the battery at each 6-monthly AS 1851 service event. Most standard 9V alkaline batteries provide sufficient life for 1–2 years in standby mode. If the alarm unit has an LED indicator, use this to monitor battery status between services. A dead battery means the extinguisher is unprotected — make battery replacement part of your routine maintenance.
Can the deactivation cable be defeated easily?
The deactivation cable provides a reasonable deterrent for opportunistic theft — cutting or pulling the cable without releasing it correctly will trigger the sounder. A determined thief with tools could defeat the mechanism, but the alarm is primarily designed to deter and detect opportunistic removal and raise an immediate alert. For locations with a history of determined theft, consider a locked cabinet (break-glass or keyed) in addition to the alarm.
Is this compatible with any fire extinguisher type?
Yes — the anti-tamper alarm mounts on the wall near the bracket and connects via a cable to the extinguisher. It is compatible with any portable fire extinguisher type — ABE, CO2, wet chemical, water, foam — regardless of size or brand. The cable attaches to the extinguisher body or handle; confirm the attachment method and cable length are compatible with your specific extinguisher when installing.
Does using an anti-tamper alarm affect AS 1851 compliance?
No — the alarm is an accessory and does not affect the extinguisher’s compliance status. The extinguisher must still be serviced under AS 1851 on schedule. The deactivation procedure for the alarm should be included in the site’s fire safety procedures and staff training — service technicians need to know how to deactivate the alarm before removing the extinguisher for service.
