TROUBLESHOOTING

KEYPAD WIRING PROTECTION CIRCUIT		ELIMINATION OF BALANCE LINE

To provide protection for incorrect keypad wiring, this CAi- Series product is equipped with a short circuit protection device. In the event of a keypad cable short, or incorrect keypad wiring, this device will automatically interrupt power to all keypad ports.

Once installed, if the keypads connected to your CAi-Series product will not turn on, the short circuit protection device may have been activated. Please take the following steps to troubleshoot the system.

1) Turn off the power switch on the front of the CAi-Series

controller.

2) Disconnect all keypad connections from the rear of the

controller.

3) Check the wiring configuration for each keypad, checking

both ends (the CAi unit and the CA keypads) of the CAT-5

keypad cable.

4) If incorrect connections were found, correct the wiring

The following diagram shows how resistors may be used at the Keypad connection on the rear of the CAi master control unit, to provide 2.5VDC to the balance control line for cen- tering. This circuit will stabilize the balance line input and keep it centered. They can be used to free up one of the 8 required conductors if one is open, shorted or if an extra conductor is needed for a secondary IR receiver’s signal in that zone. Position #7 is GND, #2 is 12VDC, #4 is Balance.

and reconnect the keypads to the controller. After the

controller has been powered off for at least 15 seconds,

turn on the power switch of the CAi-Series controller.

5) If the problem persists, repeat steps above trying each

keypad consecutively.

6) Inadequate ventilation can allow normal heat to build up

and trip the protection circuit.
