Note: The unit can also be powered
by 24-48V DC PABX battery supply on
terminals 50 and 25.
Installation
Note: Loop start and ground start CO lines may be combined on the
PF-6A (see Programming). When ground start lines are used, pin 50
(V/S) must be connected to a good earth ground.
It is recommended that the first six C.O. lines be interfaced with the
PF-6A as shown in the chart to the right.
If your system has an alarm contact or manual transfer switch, you
must connect it to the red and green wires of the modular jack labeled
EXTERNAL ALARM on the left side of the PF-6A. This must be a
normally open maintained contact closure. If normally closed alarm
contacts are used, wire them to break the power to the PF-6A when
they open.
Important: This unit is not protected against damage from power line surges. A surge protector is recommended if
operated on 120V AC.
