2.3 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 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
220 VAC, 50 Hz, 2.3 amps. Run a pair of wires (with ground conductor) from the protected premises main
breaker box to AC Power Terminal of the main circuit board. As per the Canadian Electrical Code, use 14 AWG
(2.00 mm
2 , 1.6 mm O.D.) or 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
2
)] to the
mounting stud located on the cabinet.
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 Battery Terminal 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
