Voltage Input

Primary Power Supply

1 2

16.5VAC 40 VA class 2 plug-in transformer (D1640)

Secondary Power Supply

4 5

12 VDC 7 Ah sealed lead acid rechargeable battery. The D9112 supports a maximum of two 12 VDC 7 Ah batteries using the D122 Dual Battery Harness.

Current Requirements

Panel - 500 mA

See the D9112 Standby Battery and Current Rating Chart for the current requirements of other system components.

Power Outputs

Continuous Power Outputs

3 24 32

1.4A maximum at 10.2 VDC to 13.9 VDC (continuous supply) total for all devices and outputs supplied at terminals 3,24, and 32, connectors J2 and J4.

Alarm Power Output

6 7

2.0A maximum at 10.2 VDC to 13.9 VDC output. Output may be steady or one of three pulsed patterns depending on programming. See the Relays section of the D9112 Program Entry Guide (74-06145-000)

Switched Aux Power

1.4A maximum at 10.2 VDC to 13.9 VDC output. Continuous output is interrupted by Sensor Reset (CMD 47) or alarm verification depending on programming. See the Relays section of the D9112 Program Entry Guide (74-06145-000)

Fire and Fire/Burglary Systems

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 1.4A (1400 mA) provided by the primary power supply (rectified AC). If current draw for the system exceeds 1.4A, connect a D8132 Battery Charger Module to the D9112. The D8132 provides an additional 1.2 Amps of rectified AC power. Combined current draw must never exceed 2.0A.
