Primary: Terminals 1 and 2 16.5 VAC 40 VA class 2 plug-in
transformer (D1640)
Secondary: Terminals 4 and 5 Sealed lead-acid rechargeable battery
(12.0 VDC, 7 Ah or 12.0 VDC, 17.2 or 18
Ah). The control panel supports up to two
12.0 VDC, 7 Ah batteries using the D122/
D122L Dual Battery Harness or two
D1218 (12.0 VDC, 17.2 or 18 Ah)
batteries using a D122/D122L.
Current
Requirement
Control Panel: Idle 225 mA; Alarm 300 mA. Refer to the Current Rating
Chart for Standby Battery Calculations section in the D9412GV4/D7412GV4
v2.00 Installation and System Reference Guide (P/N: F01U265457) for the

Fire and Fire/
Burglary
Systems
To comply with UL 985 and 864 listing standards for fire
alarm systems, the total combined continuous and alarm
current draw for the system during alarm conditions must
be limited to 1.4 A provided by the primary power supply
(rectified AC). If current draw for the system exceeds 1.4
A, use a UL Listed 12 VDC regulated, power limited
auxiliary power supply module such as the B520 (refer to
the Keyswitch Wiring section).
