Product Details

The PF-6A power failure bypass system makes it possible to receive calls during phone system and power outages. The PF-6A bypass unit connects 6 pre-assigned single line station phones directly to user-assigned CO trunks. A built-in ground start converter permits outbound calls from standard phones.

When the system is restored, calls in progress are not lost. The PF-6A bypass unit will reconnect phones to their station circuits after they become idle.

The PF-6A can be configured to operate when power is lost or from an opening/closing of an alarm contact or manual closure.

Alternatively, the PF-6A can be used to convert six incoming ground start lines to loop start lines. This accommodates installation of telephony equipment requiring loop start lines (example: key systems, call sequencers, answering machines, voice mail, etc.)

Applications

Prevents busy signals or unanswered calls during power and system failures
Converts ground start lines to standard loop start lines
