Conventional Fire Alarm System employs one or more initiating circuits linked to sensors wired in parallel. The number of such circuits used limits the information density. Best utilized for smaller applications, a conventional fire alarm remains a viable fire protection solution.

Conventional fire alarm system use zones. Multiple devices, both initiating and notification devices, make up a zone that connects to the main control panel. Conventional systems are analog in that they use electrical currents to communicate with the control panel.

Conventional system relies on individual circuits to communicate with the control panel. The panel’s ability to receive information limited by the number of devices it can support.
