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. The primary power
source for the panel is 120 VAC, 50/60 Hz, 2.3 amps. Run a pair of wires (with ground
conductor) from the protected premises main breaker box to TB8 of the main circuit
board. As per the National Electrical Code, use 14 AWG (2.00 mm
heavier gauge wire with 600V insulation. No other 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
mounting stud. 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 J8 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.
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.
