KT-PC4204 - 4-Relay and Additional Power Supply Module
KT-PC4204 Introduction
The KT-PC4204 module is an output module with four
programmable relays. This module can be used to “repower” the
Combus. The KT-PC4204 can also be used for elevator control.
NOTE:
Do not use any power supply other than the KT-PC4204
module to repower the Combus. If a power supply other
than the KT-PC4204 is used, the Combus repower
function will not operate as intended.

Unpacking the KT-PC4204
The KT-PC4204 package should include the following parts/items:
•
One KT-PC4204 circuit board
•
One ground wire assembly
•
Five plastic standoffs
•
One 5 A replacement fuse
Mounting the KT-PC4204
The KT-PC4204 should be located inside a compatible cabinet
(Kantech part no. KT-4051CAB), mounted in a dry, secure
location. Preferably, it should be placed at a convenient distance
from the connected devices. Perform the following steps to mount
the unit:
1. Push the five plastic standoffs through the mounting
holes on the back of the cabinet.
2. Secure the cabinet to the wall in the desired location. Use appropriate wall anchors when securing the cabinet
to dry wall, plaster, concrete, brick or other surfaces.
3. Press the circuit board into the plastic standoffs to secure the module to the cabinet.
NOTE:
Wiring may take place once the unit is mounted.
Installation and Wiring
Before wiring 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 terminal respectively.
2. If the module is used for Combus Repower,
connect the Combus wires according to the
diagram on the right. Note that for this
option, Jumper J1 must also be set to
“Combus Relay”.
3. Complete all output wiring.
4. Connect the external tamper switch, if used.
Applying Power
After wiring is completed, apply power to the KT-300. Connect the battery leads to the battery, and connect the AC transformer.
Then, connect power to the KT-PC4204; the battery leads followed by the AC transformer.
NOTE:
Do not connect the power until all wiring is complete.
