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.
The self-resetting circuit breakers include:
–
–
Notice!
A short circuit on one terminal disrupts power to the other two terminals.
–
–
Notice!
UL requires any device powered from a power output to be supervised.
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
Power devices requiring continuous power.
6
Programmable output normally open, power on alarm.
7
Programmable output normally open, power on alarm.
8
Programmable output normally closed, switches power off when the Sensor Reset command
is executed.
26
Powers serial device interface (SDI) keypads, or use to power serial device interface 2 (SDI2)
devices, such as keypads and expansion modules.
