The PF-6A can also be used to convert six incoming ground start lines to loop start
lines. This accommodates installation of telephony equipment requiring loop start lines
(i.e: key systems, call sequencers, answering machines, voice mail, etc.).
When the system is restored, you will not lose calls.
Viking’s PF-6A bypass unit will reconnect phones to
their station circuits after they become idle.
• Prevents busy signals or unanswered calls
during power and system failures
• Converts ground start lines to standard loop
start lines
The PF-6A can be configured to operate when power is lost or from an opening/closing
of an alarm contact or manual closure.
