2.2 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 120 VAC, 60 Hz, 3.66 amps for the MRP-2001 or 240 VAC, 50 HZ, 2.085 amps for the
MRP-2001E. 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
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
grounding stud 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.
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.
