KT-300 - ENGLISH INSTALLATION MANUAL
KT-PC4108 - 8-Zone Input Expansion Module
1. Introduction
The KT-PC4108 module is a zone input module that adds up to 8 fully
programmable zones to the KT-300 controller.
2. Specifications
•
Connects to the controller via 4-wire Combus
•
Current draw: 30 mA (from Combus)
•
Supports single end-of-line and no end-of-line (5600 ohm resistors)
zone loops.
•
AUX+ output: 12VDC, 250mA max. (drawn from Combus)
•
Tamper contact input
3. Installing the KT-PC4108 module
3.1
Unpacking
The KT-PC4108 package includes the following parts:
• One KT-PC4108 circuit board
• 16 end-of-line resistors (5600 ohm)
• Four (4) plastic standoffs
3.2
Mounting
The KT-PC4108 module 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 any other surfaces.
3. Press the circuit board into the four (4) plastic standoffs to secure
the unit to the cabinet.
Once the unit is mounted, wiring may be started.

Installation and Wiring
Before beginning to wire the unit, ensure that all power (AC trans-
former 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).
3. Connect the external tamper switch, if used.
Consult the wiring diagram above for further information.
2.4
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,
3. A serial number should be displayed on the screen. In the same
window where 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 -- assign modules for
more details).
Note: Don't forget to reconnect the tamper switch (or the wire, if there
is no tamper switch)
