Will my Intruder Alarm Work if There is a Power Cut?

Having an intruder alarm system in place for your business gives you peace of mind that your property is protected from theft, damage and unauthorised access. But what happens if there is a power cut? Will your intruder alarm continue to work as normal?

In many cases, intruder alarms may start beeping during or after a power cut. This can happen when the system has lost mains power or when the backup battery does not have enough power to keep the system running correctly.

What happens next will depend on the type of alarm system you have, how it communicates and the condition of its backup power supply.

If your intruder alarm relies on an internet connection, a power cut can affect both your security system and your router.

Without power, your internet connection may stop working. This can prevent the alarm from communicating with a monitoring centre until the internet connection is restored.

For this reason, it is important to understand how your alarm system communicates and whether it has a reliable backup option in place.

Your alarm panel and its communication equipment both need to be considered. A working backup battery may keep the panel operating, but the ability to send an alert also depends on the connection and any other equipment it uses.

Backup duration varies with the system, battery condition and connected equipment. Ask your service engineer to confirm the expected operation of your particular installation, including any router, communicator and alternative signalling path.

At a service visit, an engineer can test the battery and check for faults that may affect performance in an outage. If your alarm uses a phone connection, ask the team to review its suitability as telephone services change.

A power cut can expose problems with an intruder alarm system, particularly if the backup battery is weak or the system has not been serviced recently.

If your alarm fails during an outage, your home or business could be left more vulnerable. This is why regular maintenance is important for both commercial and domestic alarm systems.
