Power Cut & burglar Alarm.

Power Cut & burglar Alarm.

Often there is a short power outage, while there is always the possibility of the unpleasant experience of a generalized power loss due to a widespread failure or natural disaster. In cases of power outages, it is very likely that you have heard alarm systems ringing repeatedly.

Why is this happening?

First of all, we need to know that the power cut is provided for in the alarms. Modern systems are based on battery backup technology, with a self-contained and rechargeable battery included in the system installation. The purpose of this technology is to provide power during a power outage.

How long does the backup power system last?

When the power goes out, the time the security system will last without power depends on the backup battery installed, this will determine the time the alarm will start sounding. Most systems have sufficient power for 24 hours. The duration decreases over time.

The role of good maintenance.

If the necessary maintenance of the backup power supply system has not been carried out, the alarm may even ring for hours. The reason for the siren sounding is simple and obvious, the necessary maintenance of the backup power system has not been done, and therefore the alarm is sounding until the battery power is completely depleted. The same happens if the batteries are damaged, without good working certifications or the necessary maintenance of the alarm has not been carried out. In conclusion, when the alarm keeps ringing after the slightest power failure, it is an indication that the batteries are running low and need to be replaced.

When does a security system need maintenance?

Every year maintenance should be carried out, including the replacement of system consumables (batteries) and a general check of the zones to ensure that everything is working properly.


Home, shop and business alarms are designed in such a way that they can hold in a potential power failure for hours, they do not stop working and the operation of the central unit is supported by the backup battery.
