Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. Primary
power source is 120 VAC, 50/60 HZ, 0.32A. Run a pair of wires from the
protected premises main breaker box to the black and white primary leads
of the MS-5012 system transformer. As per the National Electric Code,
use 14 AWG (1.6 mm O.D.) or heavier gauge wire with 600V insulation
wiring. 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.
Connect the backbox ground stud to a solid earth ground (a metallic cold
water pipe may be suitable in some installations). This connection is
vital to maintaining the control panel's immunity to unwanted transients
generated by lightning and electrostatic discharge.
Secondary Power Source (Batteries)
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.
