Installing the PC4108A
3.1
Unpacking
The PC4108A package includes the following parts:
• One PC4108A circuit board
• 16 end-of-line resistors (5600 ohms)
• Three plastic stand-offs
3.2
Mounting
The PC4108A should be located inside a compatible
cabinet, 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 plastic stand-offs 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 three plastic stand-
offs to secure the module to the cabinet.
Once the unit is mounted, wiring may be completed.
3.3 Installation and Wiring
Before beginning to wire the unit, ensure that all power
(AC transformer and battery) is disconnected from the
control panel.
Perform the following steps to complete wiring:
1. Connect the four Combus wires to the PC4108A.
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 control panel Installation Manual for
details on zone wiring configurations.
3. Connect the external tamper switch, if used.
Consult the wiring diagram above for further information.
3.4 Applying Power
After all wiring is completed, apply power to the control panel.
Connect the battery leads to the battery, then connect the AC
transformer. For more information on control panel power
specifications, see the control panel Installation Manual.
NOTE
: Do not connect the power until all wiring is
complete.
4.
Enrolling the Module
Once all wiring is complete, the module must be enrolled
on the system. To enroll the module, perform the
following:
1. Enter installer’s programming by pressing [*] [8]
[Installer’s Code].
2. Scroll to “Module Hardware” and press the [*] key.
3. Scroll to “Enroll Module” and press the [*] key.
4. Scroll through the different modules until “PC41XX”
is displayed. Press the [*] key.
5. The message “Create Tamper on Desired Unit” will
be displayed. To create the required tamper, secure
the tamper zone on the module and then open it. The
transition from secure to violated enrolls the module.
After this is done, the keypad will display the module
number and will confirm enrollment (e.g. “PC4108
Mod 01 Enrolled”).
Please refer to the System Installation Manual for information on limitations regarding product
use and function and information on the limitations as to liability of the manufacturer.
