3. Installing the PC4702BP

3.1 Unpacking

The PC4702BP package includes the following parts:

• One PC4702 circuit board

• one PT1024 28V

• Four plastic stand-offs (for PC4702 board)

• One - PC4052CR red cabinet, or PC4052C beige cabinet – 12.0”W x 12.0”H x 4.5”D with space for two

DC, 4.0Ah sealed lead-acid rechargeable batteries

12 V

• Two listed 2200Ω resistors

AC, 175VA transformer

3.2 Mounting

Install the PC4702BP in the PC4052CP cabinet, mounted in a dry, secure location at a convenient distance from the connected devices.

Perform the following steps to mount the unit:

1. Press the four 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 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 PC4702BP. Connect the red, black, yellow and green Combus wires to the RED, BLK, YEL and GRN terminals, respectively.

2. Complete all other wiring according to the wiring diagrams above.

3. Consult the wiring chart on the back of this sheet.

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.

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.

4. Enrolling the Module

Once all wiring is complete, the module must be enrolled on the system. To enroll the module:

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 “PC4702 Fire” is displayed. Press the [*] key.

5. The keypad will prompt, “Create tamper on desired unit.” After you create and restore the tamper (see Tamper Wiring on front), the keypad will confirm enrollment (e.g. “PC4702 Fire Mode XX Enrolled”).

For more information regarding module enrollment, see the control panel Installation Manual.

5. Programming the Module

To access PC4010/PC4020 programming, enter [*][8] followed by the Installer’s code.
