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 specified in Output Options programming.

Terminal 10 is the ground reference for terminal 5. See the Notification Appliance section for a list of approved

notification 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 Series 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 ZA714 or ZA715 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 Series 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 fire 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) fire zone. This zone is suitable for connecting waterflow devices,

heat detectors, and other non-powered fire devices. For programming purposes, this is zone number 1. The zone is rated

for 1.66mA at 5.0 VDC.
The zone configuration on terminals 11 to 14 are described below.

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.
