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.)

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 C.O. trunks. A built-in ground
start converter permits outbound calls from stan-
dard 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.
