• Transfers six C.O. trunks directly to the
designated analog station phones
• Stackable to increase capacity
• Allows user to receive calls, as well as make
calls during power or system failure
• Compatible with loop start lines or 48V ground
start lines
• Automatic ground start converter eliminates
“ground start buttons”
• Power restoration will not interrupt calls in
progress
• Operates on power failure or normally open -
normally closed alarm contacts
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.
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.)

FCC REQUIREMENTS
This equipment complies with Part 68 of the FCC rules. Located on the equipment is a label that contains,
among other information, the FCC registration number and ringer equivalence number (REN). If requested, this
information must be provided to the telephone company.
The REN is used to determine the quantity of devices which may be connected to the telephone line.
Excessive REN's on the telephone line may result in the devices not ringing in response to an incoming call. In
most, but not all areas, the sum of the REN's should not exceed five (5.0) To be certain of the number of devices
that may be connected to the line, as determined by the total REN's, contact the telephone company to deter-
mine the maximum REN for the calling area.
This equipment cannot be used on the telephone company-provided coin service. Connection to Party Line
Service is subject to State Tariffs.
If this equipment causes harm to the telephone network, the telephone company will notify you in advance

C.O. Lines PABX/KSU
The first six C.O. lines should be interfaced with the PF-6A as shown in the chart to
the right. The PF-6A is sensitive to the polarity of the incoming telephone lines,
even when using loop start lines. There is a feature in the PF-6A that keeps a “power
fail” call from getting interrupted when power is restored (power restoration will not
interrupt calls in progress). With loop (or ground) start lines, if the C.O. dial tone
coming in is connected in the wrong polarity, this feature will not work. When wired
in reverse polarity and power is restored, a call in progress is dropped immediately.
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 EXTER-
NAL ALARM on PF-6A. This
must be a normally open main-
tained contact closure. If normal-
ly closed alarm contacts are
used, wire them to break the
power to the PF-6A when they
open.
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.

Earth Ground (V/S) Important: Pin 50 MUST be connected to a good earth ground
for the PF-6A to function properly with ground start lines.
Important: Do NOT connect the
power adapter when using the PF-6A
in the Ground to Loop Start application.
The C.O. lines must be connected
in the correct polarity.

After installing and testing the PF-6A, instruct office personnel that in the event of the power failure or system failure that the six
assigned telephones will be the only means to receive and place calls.
While the PF-6A is in normal operating mode, the six C.O. lines are connected to the trunk inputs, and the six assigned station cir-
cuits are connected to their six telephones. In the event of either a power failure or a major PABX alarm, the PF-6A will shift into
the bypass mode. In this mode, the six C.O. trunks are instantly connected to the six analog telephones designated, bypassing the
PABX/KSU. Incoming calls will now ring directly to the telephones assigned to the six C.O. trunks. Outgoing calls may also be made
from each telephone, even on ground start lines.
When power is restored or the major alarm is cleared, the PF-6A will automatically switch back to normal operation. Any C.O. trunk
in use at this time will remain connected until the call is completed.

The PF-6A can also be used as a ground start to loop start converter. This accommodates the installation of telephony equipment
requiring loop start lines (ie; key systems, call sequencers, answering machines, voice mail systems, etc.), to ground start C.O.
trunks. See Installation for proper wiring in this application.
In this application, the PF-6A will not pass disconnect supervision (“hang up” signals) to the loop start equipment. When a hang up
occurs, the PF-6A’s ground start converter automatically “restarts” the line and dial tone is returned to the loop start equipment. The
loop start equipment will not detect any disconnect, as this “restart” occurs immediately after the hang up. Typically this will cause
the loop start equipment to not release the telephone line when a caller abandons. Nothing can be done about this situation, as the
PF-6A can not distinguish the difference between this abandon condition and the loop start equipment going “off hook” to make an
outgoing call.
Note: The PF-6A can ONLY be used to convert ground start lines to loop start. It can NOT convert loop start lines to ground start.
After installation is complete, test the PF-6A by doing ONE of the following:
1. Press and hold the TEST button
2. Move DIP switch 1 to the ON position
3. Disconnect power to the PF-6A
4. Provide a maintained normally open contact closure to the EXTERNAL ALARM input
