Power supply
CAUTION: Do not apply power to the controller until after you complete and test all
connections, and after you fix the unit to the wall.
CAUTION:
Do not connect the controller to the PoE or PoE+ injector and to an external 12
VDC power supply at the same time.
To power the controller, complete one of the following procedures:
• Powering the KT-1
• Powering the KT-1 or KT-1-PCB using PoE or PoE+
• Powering the KT-1-PCB in a KT-1-CAB
• Powering the KT-1-PCB using an external power supply
Powering the KT-1
1. Connect an external power supply to the 12 VDC input terminals that are located on the small
board.
2. Install the small board to the wall plate.
3. Install the main boards to the small board.
Powering the KT-1 or KT-1-PCB using PoE or PoE+
1. During the installation, connect the Ethernet wire to the RJ-45 connector.
Note: Use PoE or PoE+ Phihong models POE125U-4-HP-R or POE36U-1AT-R.
2. Put the main board back into place.
Powering the KT-1-PCB in a KT-1-CAB
1. Connect a KT-PS4085 power supply, a PTC 1640UG plug-in adapter, and a battery rated
12V/7Ah.
2. Connect the AC trouble output from the KT-PS4085 to one of the available inputs on the KT-1
to transmit AC loss events to the monitoring console.
