WARNING: Several different sources of power can be connected to this panel. Disconnect all
sources of power before servicing. The panel and associated equipment may be damaged by
removing and/or inserting cards, modules or interconnecting cables while this unit is energized.
Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. Refer to AC Power in the
section titled "Specifications" on page 14, for power and current requirements for each FACP
version. Run a pair of wires (with ground conductor) from the protected premises main breaker
box to the AC terminal block TB1 on the main power supply. As per the National Electrical Code,
use 14 AWG (2.00 mm
equipment may be connected to this circuit. In addition, this circuit must be provided with
overcurrent protection and may not contain any power disconnect devices. A separate Earth
Ground connection must be made to ensure proper panel operation and lightning and transient
protection. Connect the Earth Ground wire [minimum 14 AWG (2.00 mm
in the backbox. Do not use conduit for the Earth Ground connection since this does not provide
reliable protection.
Secondary Power Source (Batteries)
Observe polarity when connecting the battery. Connect the battery cable to J12 on the main circuit
board using the plug-in connector and cable provided. The battery charger is current-limited and
capable of charging sealed lead acid batteries. The charger shuts off when the system is in alarm.

can destroy fabrics. If contact is made with sulfuric acid, immediately flush the skin or eyes with
