Aug 7, 2020 · Learn what the role and primary components of a fire alarm system are and the basics of how these components work together to protect your building and its occupants in the event of a fire.
- Fire Alarm Control Panel. The fire alarm control panel, commonly abbreviated as FACU, is the system’s “brain.” It receives messages from the initiating devices, also known as inputs, and performs the following functions.
- Initiation Devices. Initiation devices initiate alarms, and, just like alarm panels, they can be either addressable or non-addressable. Some initiation devices, like water flow switches, are traditionally non-addressable, but connect with addressable modules.
