2.0 Overview
16.5 VAC 40 VA class 2 plug-in transformer (D1640)
Sealed lead-acid rechargeable battery (12 VDC, 7 Ah or 12 VDC, 17.2 or
18 Ah). The panel supports a maximum of two 12 VDC, 7 Ah batteries
using the D122 Dual Battery Harness or two D1218 (12 VDC, 17.2 or 18
Ah) batteries using a D122.
1.4 A maximum at 10.2 VDC to 13.9 VDC (continuous supply) total for all
devices and outputs supplied at Terminals 3, 24, and 32 and at the
Accessory and Programming Connectors.
2.0 A maximum at 10.2 VDC to 13.9 VDC output. Output may be steady or
one of three pulsed patterns depending on programming. See Relays in the
D9412G/D7412G Program Entry Guide.
1.4 A maximum at 10.2 VDC to 13.9 VDC output. Continuous output is
interrupted by Sensor Reset or alarm verification depending on
programming. See Relays in the D9412G/D7412G Program Entry Guide.
To comply with UL 985 and 864 listing standards for fire alarm systems (effective March 1,
1989), the total combined continuous and alarm current draw for the system during alarm
conditions must be limited to 1.4 A (1400 mA) provided by the primary power supply (rectified
AC). If current draw for the system exceeds 1.4 A, remove connected devices until the current
draw falls below 1.4 A. Then, connect the removed devices to a D8132 Battery Charger
Module or to an external power supply (see Figure 26).
9 VDC 4572 m (15000 ft.) maximum

13.8 VDC Charging status LED on.
12.1 VDC Low Battery and AC Fail Reports if programmed. Low Battery LED on.
10.2 VDC Battery load shed (processing functions continue if AC is present).
AC ON Load shed relay resets, battery charging begins, Battery Trouble and AC
Restoral Reports sent.
13.7 VDC Battery Restoral Report sent, Low Battery LED off.
13.9 VDC Charging status LED off, battery float charged.

Open Greater than 3.7 VDC, but less than 5.0 VDC.
Normal Greater than 2.0 VDC, but less than 3.0 VDC.
Short Greater than 0.0 VDC, but less than 1.3 VDC.
