Terminals
TBl-1 and TBl-3 = +24V OUTPUT from Fuse F4 (via Fl).
TBl-5 and TBl-7 = +24V OUTPUT from Fuse F5 (via F2).
TBl-2, -4, -6, -8 and -10 = 24VDC COMMON.
TBl-9 = PMSI. Normally OV. +24V when power supply is in trouble or PMS circuit is open (etch-connected to P3-1).
Install jumper wire between TBl-9 and TBl-10 on the last supply w/Daisy chain.

POWER CHARGER ASSEMBLY (562-812)
Features and Functions
Required when the System Standby Battery capacity exceeds that which the Master Power Supply can keep fully
charged.
May mount within the main fire alarm panel or outside the panel.
l
When mounted within the panel, capable of charging batteries of up to 50Ah capacity; when mounted outside the
panel, capable of charging batteries of up to 1 OOAh capacity.

Fuse Fl
8A Slo-Blow for charging up to 50Ah batteries; 15A for charging up to 1 OOAh batteries.
Jumpers
NOTE:
The following jumpers are zero-ohm resistors.
JWl = OUT if ammeter connected to TBl-3 and TBl-4. Otherwise, IN.
JW2 = IN if battery checks are required. Otherwise, OUT.
JW3 = IN except when making High/Low Charge Rate Adjustment.
