Activation of Smoke Detectors:

Unwanted fire alarms can be caused by the activation of smoke detectors. These activation can be caused by airborne toxins, fumes produced through cooking, insects and steam or dust. Ensure that staff and contractual workers know where detectors are so that they can be careful when doing errands.

Faulty Detectors:

Testing and Maintenance:

Before starting any testing or maintenance, you should tell your alarm centre that the tests and maintenance are being held and also tell them when it ends. Of course, you only have to inform the alarm centre if your system is being monitored.
