3. Installing the KT-PC4204
3.1. Unpacking
The KT-PC4204 package should include the following parts/items:
•
One (1) KT-PC4204 circuit board
• One (1) ground wire assembly
• Five (5) plastic standoffs
• One (1) 5A replacement fuse

Press the five (5) plastic standoffs through the mounting holes at back of the
cabinet,
2. Secure the cabinet to the wall in the desired location. Use appropriate wall
anchors when securing the cabinet to drywall, plaster, concrete, brick or
other surfaces,
3. Press the circuit board into the plastic standoffs to secure the module to the
cabinet.
Once the unit is mounted, wiring may be started.
3.3. Installation and Wiring
Before beginning to wire the unit, ensure that all power (AC transformer and
battery) is disconnected from the KT-300 controller.
Perform the following steps to complete wiring:
1.
Connect the four Combus wires to the KT-PC4204. Connect the red, black,
yellow and green Combus wires to the RED, BLK, YEL and GRN
terminals, respectively.
If the module is being used for Combus Repower, connect the Combus wires
according to the following diagram. For this option, Jumper J1 must also be
set for “Combus Relay.”
2. Complete all output wiring,
3. Connect the external tamper switch, if used.
Consult the above wiring diagrams for further information.
