On-Board Outputs

The panel supports up to four on-board programmable outputs (PO1 to PO4).
PO2 can be configured as a supervised siren driver. Refer to Global Output Configuration in the D6412/D4412 Program Entry
Guide (P/N: 45351) for programming instructions. When programmed as a siren driver, PO2 draws power from the Alrm +
terminal. When connected to a 4 Ω horn/speaker, PO2 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.
• PO1: PO1 terminals can be configured as an alarm power output. JP2-PO1 Jumper must be closed. The default
configuration for PO1 makes it a dry contact, Normally Open relay with PO1 Jumper open (see Figure 24).

PO1 Wiring (with PO1 Jumper shorted)
• PO2: Output PO2 can be used with Alarm+ as a supervised siren driver. Connect an approved 4 or 8 Ω siren.
Alternatively, PO2 can sink up to 500 mA 12 VDC. For larger loads, use a Bosch Security Systems D133 Relay
Module or a Bosch Security Systems D134 Dual Relay Module.
• PO3 and PO4: Outputs PO3 and PO4 can be configured for Alarm Output. These outputs can sink up to 500 mA
12 VDC each. For larger loads, use a Bosch Security Systems D133 Relay Module or a Bosch Security Systems
D134 Dual Relay Module (see Figure 25).
Use the Fire System Power Formula (see Section 5.4.1 Available Power) to calculate the current available for fire
and combined fire/burglary systems.
