D9412GV2/D7412GV2 Operation and Installation Guide 6.0 Power Outputs

6.4.2Terminals 6 and 7

When activated, Terminals 6 (Relay A) and 7 (Relay B), provide positive (+) 10.2 VDC to 13.9 VDC power output. Use the power at Terminals 6 and 7 to power bells, siren drivers, piezoelectric fire sounders, electronic horns, or other devices.

Programming determines the format of the output and the conditions that activate it. One PTC protects Terminals 6, 7, and 8 against shorts.

Available Power

The system combines the 1.4 A of primary power produced by the power supply with the secondary power source (the battery) to produce a total of 2.0 A of alarm power at 10.2 VDC to 13.9 VDC. Terminals 6 and 7 share the available alarm power.

Power Restricted for Fire and Combined Fire and Burglary Systems: Fire systems are prohibited from using the battery for determining alarm power. Use the fire system power formula that follows to calculate the current available for fire and combined fire and burglary systems.

6.4.3Fire System Power Formula

To calculate the current available at Terminals 6 and 7 for fire and combined fire and burglary systems:

1.Add together the current draws for all devices connected to Terminals 3, 8, 24, and 32, and the accessory connector. This is the total current required for the normal standby condition (NSC).

2.The current available for NSC is 1.4 A. Subtract the NSC current required calculated in Step 1 from the NSC current available, 1.4 A. The difference is the alarm current available for Terminals 6 and 7.

In formula format:

1.4 A − NSC current required

= Alarm current

(Step 1)

available

Refer to the D9412GV2/D7412GV2 Approved Applications Compliance Guide (P/N: F01U003639) for module or accessory current requirements.

6.4.4Terminal 8

Terminal 8 provides continuous positive (+) 10.2 VDC to 13.9 VDC power. Relay C interrupts the power at Terminal 8 when activated. Use Terminal 8 to power smoke detectors or other devices that are reset by interrupting power. One self-resetting circuit breaker protects Terminals 6, 7, and 8 against shorts.

Verification/Reset Relay

The default program sets Relay C (Terminal 8) as a verification and reset relay. Refer to Relay Parameters and Point Assignments in the D9412GV2/D7412GV2 Program Entry Guide (P/N: F01U003636) for instructions on programming verification and reset relays and points.

Performing a sensor reset at a keypad produces a five- second relay activation of verification/reset relays. The control panel ignores verification/reset points during the five seconds.
