Introduction
Description
The Potter PFC-7500/PFC-7501 Commercial Fire Panels are powerful 12 VDC fire alarm communicators with battery backup that can also be powered from the 12 or 24 VDC auxiliary output of a Fire Alarm Control Panel (FACP). Each panel provides one Class A (Style D) fire zone and four Class B (Style A) powered fire zones with reset capability for 2-wire smoke detectors, relays, or other latching devices.
In order to power the PFC-7500/PFC-7501 from the 12 VDC or 24 VDC of an FACP, the FACP must operate as a grounded control panel. If the FACP is a non- grounded system, it may detect a ground fault when connected to the PFC-7500/PFC-7501 panel AC or DC Input terminals. In this case the panel should be powered from a separate WLT wire-in transformer and not from the FACP.
The PFC-7500/PFC-7501 panels can communicate to one or two Potter SCS-1R Receivers using SDLC digital dialer or up to two non-Potter (Contact ID) receivers using the CID reporting format.
Zone Expansion
Up to 4 additional zones are available on the PFC-7500/PFC-7501 using a 714 or 715 zone expansion module. The panel keypad data bus supports one supervised device address with up to four programmable expansion zones. The four zone numbers are 31-34.
Note: Do not use shielded wire for Keypad Bus circuits.
Caution Notes
Throughout this guide there are caution notes containing information about installing the panel. These cautions are indicated with a yield sign. Whenever you see a caution note, make sure you completely read and understand its information. Failing to follow the caution note can cause damage to the equipment or improper operation of one or more components in the system. See the example shown below.
Always ground the panel before applying power to any devices: The PFC-7501 must be properly grounded before connecting any devices or applying power to the panel. Proper grounding protects against Electrostatic Discharge (ESD) that can damage system components.
Compliance Instructions
For applications that must conform to a local authorities installation
standard or a National Recognized Testing Laboratory certificated system,
please see the Wiring Diagrams for Notification Appliances and the Listed
Compliance Specifications section near the end of this guide for additional
instructions.

You can connect the Models RA-7630 or RA-7692 keypads to the 4-wire keypad bus provided by the panel on terminals 7, 8, 9, and 10. Do not use shielded wire for the keypad bus.
Installation
Mounting the Enclosure
Mount the metal enclosure for the PFC-7500/PFC-7501 panels in a secure, dry place to protect the panels from damage due to tampering or the elements. It is not ecessary to remove the PFC-7500 or PFC 7501 PCB when installing the enclosure.
Figure 3: Mounting the Enclosure
TAM Trouble Annunciator Module
The TAM Module is installed on the enclosure door and connects to the panel
through a 4-wire harness supplied with the
module. See Figure 4.
Figure 4: TAM Module Wiring
TAM Module Operation
The TAM Trouble Annunciator Module provides visual and audible annunciation of
System Okay, communication trouble, and panel processor failure. The module
contains a Green LED for System Okay, a Yellow LED for Trouble, an
electronic sounder, and a Silence switch.
System Okay
When both phone lines are normal and the panel processor is operating, only
the Green LED on the TAM Module is on.
This LED goes off during a Sensor Reset.
Communication Trouble
If either phone line connected to the panel is in a bad condition, or if the
panel has made TEN failed attempts to send a report to the central station
receiver, the TAM Module emits a steady audible alert and turns on the Yellow
LED. The Silence switch can be used to turn off the sounder only.
Panel Processor Failure
During a processor failure on the panel, or a remote programming session, the
TAM Module emits a steady audible alert and turns on the Yellow LED.
The Silence switch does not turn off the sounder or
Yellow LED during these conditions.
Mounting Keypads
Potter keypads have removable covers that allow you to easily mount the base to a wall or other flat surface. After installing the keypad mounting anchors and bringing the keypad wiring from the panel through the wall, mount the base and connect the keypad wire harness leads to the keypad wiring. Next, attach the keypad wire harness connector to the pin connector on the keypad circuit board and install the cover.
For mounting keypads on masonry walls, or for applications where conduit is required, use an appropriate Security Command keypad conduit backbox.
Wiring Specifications for the Keypad Bus
-
You can install individual keypads on wire runs of up to 500 feet using 22 gauge wire or up to 1,000 feet using 18 gauge wire. To increase the wire length or add additional devices, a power supply is required.
-
Maximum distance for any one keypad bus circuit (length of wire) is 2,500 feet regardless of the gauge of wire.
This distance can be in the form of one long wire run or multiple branches with all wiring totaling no more than 2,500 feet. -
Maximum number of devices per 2,500 feet circuit is 40. (Refer to the Keypad Bus section for the specific number of supervised keypads that are allowed.)
-
Maximum voltage drop between the panel (or auxiliary power supply) and any device is 2.0 VDC. If the voltage at any device is less than the required level, an auxiliary power supply should be added at the end of the circuit.
Note: Do not use shielded wire for the keypad bus.
Terminal Wiring Connections See Figure 5.
Figure 5: Wiring Connections
CAUTION
Do not use looped wire under terminals.
Break wire run to provide supervision of connections.
Primary Power Supply
Installing the Transformer
The transformer requires an unswitched 120 VAC 60 Hz electrical outlet with at
least 350mA of available current. Never share the transformer output with any
other equipment. The 120 VAC circuit is not power limited.
To mount the Model WLT Transformer to a single-gang box adjacent to the
PFC-7500/PFC-7501 enclosure, follow the steps below. Refer to Figure 6 as
needed.
Figure 6: Transformer Installation
- Remove the lower knockout from the PFC-7500/PFC-7501 enclosure.
- Attach a single-gang box adjacent to the PFC-7500/ PFC-7501 enclosure.
- After the single-gang box is secured, attach the transformer to the junction box, using the bottom box’s bottom knockout. The screw on the transformer should extend into the single-gang box.
- Tighten the screw to secure the transformer to the junction box .
- An electrician must then connect the black and white leads on the transformer to an unswitched 120 VAC 60 Hz electrical outlet with at least 550mA of available current.
- Connect the wires from the bottom (the side opposite the attaching screw) two terminals on the transformer to terminals 1 and 2 on the panel. Use no more than 70 ft. of 16-gauge wire or 40 ft. of 18‑gauge wire between the transformer and the PFC-7500 or PFC-7501 panel.
Terminals 1 and 2
The transformer provides up to 500mA of auxiliary current for the PFC-7500/PFC
7501 panels. The total current available is limited by the total battery
standby requirements of the installation. See the Power Requirements section
for standby battery calculations.
Note: After power is applied to the PFC-7500/PFC-7501 panel, any SNM
Notification Modules connected to the panel display Bell Trouble for 20
seconds.
DC Power Input to AC Input
When powering the PFC-7501/SL panel from the 12 VDC output of an FACP, connect
the positive wire to the positive battery terminal of the PFC-7500/PFC-7501
and the negative wire to the negative battery terminal of the PFC-7500/
PFC-7501.
When powering the panel from the DC output of a 24 Volt Fire Alarm Control Panel (FACP), connect the positive wire from the FACP to terminal 1 and the negative wire to terminal 2. In order to power the PFC-7500/PFC-7501 from the 12 VDC or 24 VDC of an FACP, the FACP must operate as a grounded control panel. If the FACP is a non-grounded system, it may detect a ground fault when connected to the PFC-7500/PFC-7501 panel AC or DC Input terminals. In this case the PFC-7500/PFC-7501 should be powered from a separate WLT wire-in transformer and not from the FACP.
Do not use battery backup with 12 or 24 VDC input: Do not connect any batteries to the PFC-7500 or PFC-7501 panels when using the 12 or 24 VDC output from a FACP. The PFC-7500/PFC-7501 panels use the backup battery capability of the FACP for their standby requirements.
When powering the PFC-7500 or PFC-7501 panel from the 24 VDC output of a FACP, the following features are disabled:
- Bell Output on the PFC-7501
- AC test (PFC-7500/PFC-7501)
- Battery test (PFC-7500/PFC-7501)
Always ground the panel before applying power to any devices: The PFC-7500/PFC 7501 panels must be properly
Secondary Power Supply
grounded before connecting any devices or applying power to the panels. Proper
grounding protects against Electrostatic Discharge
(ESD) that can damage system components. See the Earth ground section.
Battery Terminals 3 and 4
Connect the black battery lead to terminal 4 on the panel and then to the negative terminal of the battery. The negative terminal connects to the enclosure ground internally through the PFC-7500/PFC 7501 panel circuit board. Connect the red battery lead to terminal 3 on the panel and then to the positive terminal of the battery. Observe polarity when connecting the battery.
The PFC-7500/PFC-7501 panels are capable of recharging two 7.7 Ah batteries (15.4 Amp/hours) within 24 hours.
Do not use battery backup with 24 VDC input: Do not connect batteries to the PFC 7500/PFC-7501 panels when powering the panels with 20 to 28.2 VDC voltage from a Fire Alarm Control Panel (FACP). The PFC-7500/PFC-7501 panels use the backup battery capability of the FACP for their standby requirements.
Use sealed lead-acid batteries only: Use only sealed
lead-acid rechargeable battery. Batteries supplied by Potter have been tested
to ensure proper charging with Potter products.
DO NOT USE GEL CELL BATTERIES WITH THE PFC-7500/PFC-7501.
Earth Ground (GND)
Terminal 4 of the PFC-7500/PFC-7501 panels must be connected to earth ground using 14 gauge or larger wire to provide proper transient suppression. Potter recommends connecting to a metal cold water pipe or ground rod only. Do not connect to electrical conduit or a telephone company ground.
Battery Replacement Period
Potter recommends replacing the battery every 3 to 5 years under normal use.
Discharge/Recharge
The battery charging circuit on the PFC-7500/PFC-7501 panels float charge at
13.9 VDC at a maximum current of 1.2 Amps using the Model WLT Transformer. The
total current available is reduced by the combined auxiliary current draw from
terminals 6, 7, 15, 17, 19, and 21. The various battery voltage levels are
listed below:
Battery Trouble: Below 11.9 VDC
Battery Restored: Above 12.6 VDC
Battery Supervision
1 and 2. The test lasts for five seconds. If, during the test, the battery voltage falls below 11.9 VDC a low battery is indicated. The test is then repeated every two minutes until the battery charges above 12.6 VDC, the battery restored voltage.
If the low battery does not recharge and is replaced with a fully charged battery, the charged battery will not be detected until the next two minute test is done.
If AC power fails during normal system operation, a low battery is indicated any time the battery voltage falls below 11.9 VDC.
PFC-7500/PFC-7501 Power Requirements
During AC power failure, the PFC-7500/PFC-7501 panels, and all auxiliary
devices connected to the panels, draw their power from the battery. All
devices must be taken into consideration when calculating the battery standby
capacity.
Below is a list of the power requirements of the PFC-7500/PFC-7501 panels. Add
the additional current draw of Potter keypads, smoke detectors, and any other
auxiliary devices used in the system for the total current required.

The PFC-7500/PFC-7501 panels each contain a mechanical push button located on
the top center of the printed circuit board that allows authorized users to
silence alarm bells or sirens and reset latched detection devices.
After pressing the button, the panel silences the Bell output (PFC-7501 terminal 5) and momentarily drops power to the auxiliary output (PFC-7501 terminal 6), the TAM Trouble Annunciator Module, and zones 2 to 5 (both panels). Additionally, any Fire or Supervisory event displays at the keypads are also cleared. A 2-pin reset header (J13) is also provided for use with keyswitches.
Bell Circuit Monitor
The PFC-7501 panel contains a bell monitor input (J14) that can be connected
to the trouble contacts of the SNM Notification Circuit Module. When the 2-pin
header is shorted via the notification module, the Bell Circuit Monitor is in
a restored condition. When the trouble contacts open, a bell circuit trouble
is indicated. The PFC-7501 is shipped from the factory with a shorting clip on
the 2-pin header to indicate a restored condition. A harness is used to
connect the J14 Bell Circuit Monitor to the trouble contacts of the SNM
Notification Circuit Module.
Dual Phone Line Connectors
Description
The PFC-7500/PFC-7501 panels contain built-in dual phone line capability that
allows the panel to monitor two phone lines, indicate a phone line failure,
and switch to the alternate phone line to communicate alarm and system reports
to a central station.
Before sending a report, the panel verifies whether the main phone line is working. If not, the panel sends the report over the backup phone line. An integrated phone line monitor circuit continually tests the phone lines and indicates a trouble condition on the line after 90 seconds. If the phone line restores and is good for 90 seconds, the panel ends the phone line trouble indication.
The maximum line impedance is 100 Ohms.
