fully programmable zones to the KT-300 door controller.
2.
Specifications
• Connects to the controller via 4-wire Combus
• Current Draw: 30 mA (from Combus)
• Supports single end-of-line (5600 ohm resistors) and
no end-of-line zone loops.
• AUX+ output: 12VDC, 250mA max. (drawn from
Combus)
• Tamper contact input

Installing the KT-PC4108 module
3.1 Unpacking
The KT-PC4108 package includes the following parts/items:
• One (1) KT-PC4108 circuit board
• Sixteen (16) end of line resistors (5600 ohms)
• Four (4) plastic standoffs
• One (1) installation instructions sheet
3.2 Mounting
The KT-PC4108 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) Press the four (4) 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 drywall, plaster, concrete, brick or other
surfaces,
3) Press the circuit board into the four (4) plastic standoffs
to secure the module to the cabinet.
3.3 Installation and Wiring
Before beginning to wire the unit, ensure that all power (AC
transformer and battery) is disconnected from the controller.
Perform the following steps to complete wiring:
1) Connect the four Combus wires to the KT-PC4108.
Connect the red, black, yellow and green Combus
wires to the RED, BLK, YEL and GRN terminals,
respectively,
2) Complete all zone wiring to the zone input terminals
(Z1-Z8). See the KT-300 Installation Manual for details
on zone wiring configurations,
3) Connect the external tamper switch, if used.
Consult the above wiring diagram for further information.
3.4 Applying Power
After all wiring is completed, apply power to the controller.
Connect the battery leads to the battery, then connect the
AC transformer.
Note: Do not connect the power until all wiring is complete.
4.
Assigning the module
Once all wiring is complete, the module must be assigned
to the system. To assign the module, perform the following
steps:
1) Establish communication between the PC and the
controller,
2) Remove the tamper switch wire (or only the wire if
tamper switch is not used),
3) A serial number should be displayed on the screen,
in the same window where is the serial number is
located, you should see the type of module and on
which controller it is connected,
4) From the software, select the functionality of the
module and enter the serial number in the appropriate
field (see your software reference manual under
controller definition -- Assigning modules for more
details).
Note: Don’t forget to reconnect the tamper switch (or the
wire, if there is no tamper switch)
