Four open collector annunciator outputs (Outputs 1 to 4). No relay is required. Each output is rated for 50mA at 30 VDC resistive. Push-Button Reset The PFC-7500/PFC-7501panels each provide a push button mounted on the printed circuit board that allows authorized users to reset latch detectors and silence active alarm bell outputs. See section 16.1. Enclosure Specifications The PFC-7500/PFC-7501 panels are shipped in an enclosure with End-of-Line resistors, battery leads, User’s Guide... -
Page 6: Introduction
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. -
Page 7: System Components
Description A basic PFC-7500/PFC-7501 system is made up of the alarm panel with built-in communicator, an enclosure, a 16.5 VAC wire-in transformer, and a 12 VDC 7.0 Ah battery. You can add up to two alphanumeric keypads and one or more LED keypads to the panel and also connect control and annunciating devices to the panel Form C and annunciator outputs. -

Page 9: 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 necessary to remove the PFC-7500 or PFC-7501 PCB when installing the enclosure. -
Page 10: Mounting Keypads
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. -
Page 11: Primary Power Supply
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. -
Page 12: Secondary Power Supply
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. -
Page 13: Pfc-7500/Pfc-7501 Power Requirements
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. -
Page 14: Bell Output
Keypad Bus Description Terminals 7, 8, 9, and 10 of the PFC-7500/PFC-7501 panels provide a Class B, Style 3.5 keypad bus to connect an unlimited number of RA-7692 LED keypads, two RA-7630 keypads, and other auxiliary devices. In addition, to keypads, connect a 714 or 715 zone expansion module to the Keypad Bus. -
Page 15: Class B (Style A) Fire Zones
11.1 Description Terminals 15 to 22 are the Class B (Style A) fire zones on the PFC-7500/PFC-7501 panels. These zones are suitable for connecting powered or non-powered fire devices. For programming purposes, these zones are designated 2 to 5. The maximum line impedance is 100 Ohms. -
Page 16: Form C Relay Outputs
Each output provides one Common, one Normally Open, and one Normally Closed terminal. Field wiring for the Form C relays connects to the 6-position terminal strip on the lower right corner of the PFC-7500/PFC-7501 boards. The Form C relays can be operated by any of the functions listed below:... -
Page 17: Notification
There is a reset jumper located at the top right of the panel circuit board labeled RESET. Momentarily shorting the metal wires of the jumper with a screwdriver resets the microprocessor of the PFC-7500/PFC-7501 panels to enter the internal Programmer. -
Page 18: Listed Compliance Specifications
Two phone lines must be used. The two phone lines cannot be ground start or party lines. Two different phone numbers must be programmed for digital communication. 20.4 Local Protective Signaling Systems The Potter SNM Notification Circuit Module must be used on the bell circuit for detection of shorts and grounds. -
Page 19: Remote Station Protective Signaling Systems
20.5 Remote Station Protective Signaling Systems 60 hours of standby battery must be provided. Up to two 12 VDC, 7.0 Ah batteries may be used. See standby battery calculations. The Radionics Model D127 Reversing Relay Modules may be used to provide two reversing polarity telephone connections instead of dual phone lines. -
