10 On-board outputs
The control panel provides one configurable (power, common, dry) and two open collector on-
board outputs.
10.1 Circuit protection
The powered outputs come with circuit protection.
Three self-resetting circuit breakers protect the control panel from short circuits on the
continuous and programmable power outputs. Each breaker protects a separate terminal:
– AUX (auxiliary power) terminal.
– C terminal of OUTPUT A.
– PWR/R terminal (power) of the SDI2 terminal block.
Notice!
UL requirement
Supervise devices powered from a power output.
10.2 Total available power
The control panel produces up to 800 mA of combined power at 12.0 VDC nominal to power
peripheral devices. The outputs listed below and OUTPUT A share the available power.
AUX terminal (auxiliary power)
AUX
Powers devices requiring continuous power (for example, motion detectors).
R/PWR terminal and power output of the interconnect connector (SDI2 power)
R
PWR
Power SDI2 devices such as keypads and octo-input modules.
Plug-in module connector
Connect plug-in modules such as the B444.
OUTPUT A
NO C NC
OUTPUT A
Configure Output A as a dry contact (contact rating is 3 Amps), switched common (sink
current), or a powered output. As a powered output, it can provide alarm power or switched
auxiliary power. The default configuration for Output A makes it a powered output providing
alarm power. Use OUTPUT PARAMETERS in RPS or in the Installer Services Portal
programming tool (available in Europe, Middle East, Africa, and China) to configure
programmable outputs.
