Conventional Fire Alarm Systems
Conventional systems divide the protected area into zones. Each zone groups a number of detection devices wired on a single circuit, and the control panel identifies which zone has triggered — useful in smaller buildings where locating the alarm by zone is sufficient.
Typical elements: conventional control panel, zone-based detection circuits, smoke and heat detectors, manual call points, and sounders or sounder strobes on notification circuits.
Suitable when: the building is compact, the zone-level location is acceptable to the consultant and authority, and the device count does not justify the additional cost of addressable infrastructure.
