Potter PFC-7500 Series - Manual (Page 6)

2.1 Description
The Potter PFC-7500 Series 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 Series 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 Series 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 Series 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.
2.2 Zone Expansion
Up to 4 additional zones are available on the PFC-7500 Series Series using a ZA714 or ZA715 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.
2.3 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.
2.4 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.
