Unpacking the KT-PC4108 Module
The KT-PC4108 package includes the following parts/items:
•
One KT-PC4108 circuit board - 9.2 cm x 3.3 cm (3
5/8
” x 1
1/4
”)
•
16 end-of-line resistors (5600 ohms)
•
Three (3) plastic standoffs with adhesive
•
One (1) installation instructions sheet
Mounting the KT-PC4108 Module
The KT-PC4108 module should be located inside a compatible cabinet (Kantech part no. KT-4105 CAB), 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 three (3) plastic standoffs through the mounting holes on either side 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 three (3) plastic standoffs to secure the unit to the cabinet.
4. Remove the protective film from the plastic standoffs and attach the circuit board to the cabinet.
NOTE:
Wiring may take place once the unit is mounted.
Installation and Wiring
Before wiring the unit, ensure that all power sources (AC transformer and battery) are 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.
NOTE:
Consult the wiring diagram above for further information.
Applying Power
After 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 completed.
Assigning the Module
Once all wiring is completed, the module must be assigned to the system. To assign the module, perform the following steps:
1. Establish communication between EntraPass and the controller.
2. Remove the tamper switch wire (or only the wire if tamper switch is not used). If there is no connection to the
TAM input, use the
Tamper Switch
button to generate an event.
3. An event will be displayed on the EntraPass workstation Desktop Message screen, indicating the module’s
serial number, type and the controller to which 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:
Do not forget to reconnect the tamper switch (or the wire, if there is no tamper switch).
