5.2.3 Alarm Power
Provides positive 12 VDC for PO 2 (Programmable Output 2) when it is configured as a siren driver and PO 1
when it is configured as the alarm output.
5.3 Continuous Power Output
5.3.1 Continuous Current Draw
The continuous current draw for powered devices connected to the Aux Power terminals, the Installer’s Keypad
Connector and Outputs PO 1 to PO 4 (when programmed for continuous output) are restricted as follows:
- 120 mA for Fire and Combined Fire/Burglary systems
- 400 mA for UL Burglary systems
- 600 mA for other applications (not investigated by UL)
5.4 Alarm Power
5.4.1 Available Power
The system combines the 600 mA of primary power produced by the power supply with the secondary power
source (the battery) to produce a total of 1.5 A of alarm power at 11.5 to 12.4 VDC. Alarm power is available at
the Alrm + terminal. The panel uses Programmable Output 1 (PO 1) through Programmable Output 4 (PO 4) to
activate Alarm power (see Section 5.5, Output Programming).
IMPORTANT
Fire systems are prohibited from using the battery for determining alarm power. Use the Fire System
Power Formula below to calculate the current available for fire and combined fire/burglary systems.
Fire System Power Formula
To calculate the current available at the Alrm + terminal for fire and combined fire/burglary systems:
1. Add together the current draws for all devices connected to the Aux terminals and the Installer’s Keypad
Connector. This total is the total current required for the Normal Standby Condition (NSC).
2. The current available for Normal Standby Condition (NSC) is 600 mA. Subtract the NSC current required
calculated in Step 1 from the NSC current available, 600 mA. The difference is the Alarm Current available
the Alrm + terminal (480 mA maximum).
In formula format:
600 mA – NSC current required (Step 1) = Alarm Current available (480 mA maximum)
Refer to Appendix A: Current Rating for Standby Battery Calculations Chart for module/accessory current
requirements.
5.5 Output Programming
Programmable Output 2 (PO 2) can be configured as a supervised siren driver. See Global Output Configuration
in the D6412/D4412 Program Entry Guide (P/N: 45351) for programming instructions. When programmed as a
siren driver, PO 2 draws power from the Alrm + terminal. When connected to a 4 Ω horn/speaker, PO 2 draws
380 mA of power. When connected to an 8 Ω horn/speaker, it draws 330 mA of power. Use the appropriate
current draw in your total alarm power calculation.
• Programmable Output 1 (PO 1): PO 1 terminals can be configured as an alarm power output. JP2-PO 1
Jumper must be closed. The default configuration for Programmable Output 1 makes it a dry contact, normally
open relay. The PO 1 Jumper is open. See Figure 5 for jumper location.
• Programmable Output 2 (PO 2): Output PO 2 can be used with Alarm+ as a supervised siren driver. Connect
an approved 4 or 8 Ω siren. Alternatively, PO 2 can sink up to 500 mA 12 VDC. For larger loads, use a
Radionics D133 Relay Module or a Radionics D134 Dual Relay Module.
• Programmable Outputs 3 & 4 (PO 3 & PO 4): Outputs PO 3 and PO 4 can be configured for Alarm Output.
These outputs can sink up to 500 mA 12 VDC each. For larger loads, use a Radionics D133 Relay Module or
a Radionics D134 Dual Relay Module.
Power restricted for fire and combined fire/burglary systems: Use the Fire System Power Formula (see
Section 5.4.1, Available Power) above to calculate the current available for fire and combined fire/burglary
systems.
