In many smaller premises or properties, where the building layout is relatively uncomplicated, a simple “conventional” system that warns of a problem may suffice.
A conventional fire alarm may simply be a control panel, a manual call point and a sounder, or it could be a multi-zone panel covering a large building.
The system consists of one or more zones each having either manually operated call points or automatic detection devices, or a combination of both. When the alarm is activated, the zone in which the activation has occurred is shown on the control panel. That enables you to concentrate your search for the cause to a specific area.
A combination of sounders and strobes warns you and others that the fire alarm has been triggered, ensuring a prompt evacuation of the building.
