About this detail

This diagram details the internal layout and terminal connections of a fire alarm control panel backbox measuring twenty-four inches wide. The assembly houses a CPU motherboard with an IDNAC card, IDNet2 modules, an event reporting DACT, and a power supply. Shaded areas within the backbox designate reserved space for non-power-limited circuitry such as AC power, batteries, and city connections, keeping power-limited wiring separate. Thirty-three amp-hour batteries connect to the system at the bottom, while terminal schedules for bay one, bay two, and bay three provide circuit labels, descriptions, and wire designations. AC power connects to one hundred twenty volts alternating current at sixty hertz.
