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 Dual Battery Harness or two D1218 (12.0 VDC, 17.2 or 18 Ah) batteries 
using a D122. 

Control Panel: Idle 225 mA; Alarm 300 mA

  

Refer to the Current Rating Chart for Standby Battery Calculations section in the D9412GV3/D7412GV3 Approved 
Applications Compliance Guide (P/N: F01U143069) for the current draw requirements of other system components. 
All external connections are power-limited except battery terminals.

Outputs 

Terminals 3, 
24, and 32 

1.4 A maximum at 12.0 VDC nominal (continuous supply) total for all devices and 
outputs supplied at Terminals 3, 24, and 32 and at the accessory and 
programming connectors. 

Alarm Power 
Output 

Terminals 6 
and 7 

2.0 A maximum at 12.0 VDC nominal output. Output can be steady or one of 
three pulsed patterns depending on programming. Refer to Relays in the 
D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807). 

Switched Aux 
Power 

Terminal 8 

1.4 A maximum at 12.0 VDC nominal output. Continuous output is interrupted by 
Sensor Reset or alarm verification depending on programming. Refer to Relays 
in the D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807). 

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 1.4 A 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 
(refer to Figure 29 on page 58). 

*For UL 864 applications, refer to 

 on page 11 for compatible devices.
