10 On-board outputs
The control panel provides three powered relay outputs.
10.1 Circuit protection
The powered outputs come with circuit protection.
Four self-resetting circuit breakers protect the control panel from short circuits on the
continuous and programmable power outputs. Each breaker protects a separate terminal or
group of terminals:
– Terminal 3, auxiliary power
– Power terminals
– Terminal 6. Alarm power output
– Terminal 7. Alternate alarm power output
– Terminal 8. Switched auxiliary power
– Terminals 26 and 30, power +
– ZONEX connection
Notice!
A short circuit on one terminal disrupts power to the other two terminals.
Notice!
UL requirement
Supervise devices powered from a power output.
10.2 Total available power
The system produces up to 1.4 A of combined power at 12.0 VDC nominal. The outputs in this
section share the available power. These outputs appear as shown on the faceplate.
3
Auxiliary power
Power devices requiring continuous power.
6
Output A (1), Alarm power output
Programmable output normally open, power on alarm.
7
Output B (2), Alternate alarm power output
Programmable output normally open, power on alarm.
8
Output C (3), Switched auxiliary power
Programmable output normally closed, switches power off when the Sensor Reset command
is executed.
26
SDIx Power+ / R
Powers serial device interface (SDI) keypads, or use to power serial device interface 2 (SDI2)
devices, such as keypads and expansion modules.
