Power Failure Telephone

Power Failure Cut-Through

When AC power fails, the system can automatically cut through to a Power Failure Telephone connection.

To install Power Failure Cut-Through (Figure 4-4):

● Connect the GRN and RED lugs on the PFT/MDM modular jack to the GRN and RED lugs on the

Power Failure Telephone’s mod jack.

To test the Power Failure Telephone:

1. Connect the power failure telephone. See the illustration below.

2. Power down the system.

3. At the Power Failure Telephone, lift the handset.

You should hear dial tone from trunk 1.

4. Place a test call.

If power is restored while a cut-through call is in progress, the call is maintained until the user

hangs up the Power Failure Telephone.

While your system is powered up, your Power Failure Telephone is extension 316.
