Smoke alarm system break glass units across the building. If the system detects a fire then an LED will light up on the detector and on the relevant zone on the main control panel so you can clearly see the area the fire is in. The control panel will then operate the warning sounders or sounder beacons which are usually on a separate circuit. Conventional fire systems start from single zone systems all way up to 32 zone systems.
