Operating Power

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 modules,
interconnecting cables or wiring while this unit is energized.
Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. The AC input circuit is limited by fuse F2 (2 amp,
3AG Slow Blow). The primary power source for the FACP is 120 VAC, 60 Hz, 0.5 amps. Run a pair of wires (with
ground conductor) from the protected premises main breaker box to TB3 of the main circuit board. As per the
National and Canadian Electric Code, use 14 AWG (2.00 mm
lation. No other equipment may be connected to this circuit. In addition, this circuit must be provided with overcur-
rent 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 [mini-
mum 14 AWG (2.00 mm
tion since this does not provide reliable protection.
Secondary Power Source (Batteries)
Observe polarity when connecting the battery. Connect the battery cable to J3 on the main circuit board using the
plug-in connector and cable provided. The battery charger is current-limited and capable of recharging sealed lead
acid type batteries. The charger shuts off when the system is in alarm. See Battery Calculations for calculation of the
correct battery rating.
!
WARNING: Battery contains sulfuric acid which can cause severe burns to the skin and eyes and can destroy fabrics.
If contact is made with sulfuric acid, immediately flush the skin or eyes with water for 15 minutes and seek immediate
medical attention.
