7.1 Terminal 5 (PFC-7501 Only)
Terminal 5 supplies 12 VDC Bell Output to power alarm bells or horns. The output is rated for a maximum of 1.5
Amps. This output can be steady or temporal depending upon the Bell Action specied in Output Options programming.
Terminal 10 is the ground reference for terminal 5. See the Notication Appliance section for a list of approved
notication appliances and the Wiring Diagrams for connections
4-Wire Smoke Detector Power
8.1 Terminal 6 (PFC-7501 Only)
Terminal 6 provides up to 100mA at 12 VDC to power 4-wire smoke detectors or other auxiliary powered devices. This
output can be turned off by the user for 5 seconds using the Sensor Reset User Menu option. Terminal 10 is the ground
reference for terminal 6.
Keypad Bus
9.1 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.
9.2 Terminal 7 - RED
Terminal 7 provides 12 VDC regulated keypad power for Potter keypads. You can also connect 12 VDC auxiliary
devices to terminal 7. The ground reference for terminal 7 is terminal 10. The maximum output is rated at 500mA on the
PFC-7500/PFC-7501 panels. All auxiliary devices totalled together must not exceed the panel’s maximum current rating.
See Power Supply in the Compliance section for maximum current in a re listed application.
9.3 Terminal 8 - YELLOW
Data receive from devices.
9.4 Terminal 9 - GREEN
Data transmit to devices.
9.5 Terminal 10 - BLACK
Terminal 10 is the ground reference for keypads and any auxiliary devices powered by terminal 7.
Note: Do not use shielded wire when wiring keypads or other devices.
Class A (Style D) Fire Zone
10.1 Description
Terminals 11 to 14 are the panel’s Class A (Style D) re zone. This zone is suitable for connecting waterow devices,
heat detectors, and other non-powered re devices. For programming purposes, this is zone number 1. The zone is rated
for 1.66mA at 5.0 VDC.
The zone conguration on terminals 11 to 14 are described below.
Terminal Function Terminal Function
11 Zone 1 voltage sensing 12 Negative for terminal 11
13 Zone 1 voltage sensing 14 Negative for terminal 13
The voltage sensing terminal measures the voltage across the circuit and the zone’s negative terminal. Dry contact
sensing devices can be used only in parallel (normally-open) with zone 1. There are no End-of-Line resistors on a Class
A (Style D) zone. The maximum line impedance is 100 Ohms.
