Power Outputs
5.5 Output Programming
Programmable Output 2 (PO2) 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, 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.
• Programmable Output 1 (PO1): PO1 terminals can be configured as an alarm power output. JP2-PO1 Jumper
must be closed. The default configuration for Programmable Output 1 makes it a dry contact, normally open
relay. The PO1 Jumper is open. See Figure 5 for jumper location.
• Programmable Output 2 (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 Bosch Security Systems D134 Dual Relay Module.
• Programmable Outputs 3 and 4 (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 Bosch Security Systems D134 Dual Relay Module.
Power restricted for fire and combined fire/burglary systems: Use the Fire System Power Formula in Section 5.4.1 Available
Power to calculate the current available for fire and combined fire/burglary systems.
Unexpected Output at PO1 to PO4: If these outputs do not provide the alarm output you expect:
• Check the programming for Programmable Outputs in the Outputs section of the D6412/D4412 Program Entry
Guide (P/N: 45351).
• Check the Point Index Configuration section of the D6412/D4412 Program Entry Guide to verify the points you
are activating are programmed for alarm output.
