11.1 Description
Terminals 15 to 22 are the Class B (Style A) fire zones on the PFC-7500 Series 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. The zone configurations on terminals 15 to 22 are described below:
Terminal Function Terminal Function
15 Zone 2 voltage sensing 16 Zone 2 negative
17 Zone 3 voltage sensing 18 Zone 3 negative
19 Zone 4 voltage sensing 20 Zone 4 negative
21 Zone 5 voltage sensing 22 Zone 5 negative
11.2 Operational Parameters
The Class B (Style A) zones on the PFC-7500 Series panels can detect three conditions: open, normal, and short. Each
zone terminates with a Model 309, 3.3k Ohm EOL resistor (provided with the panel) and is rated for 53mA at 12 VDC.
The compatibility identifier for use with 2-wire smoke detectors is: A.
11.3 Zone Response Time
A condition must be present on the zone for at least 500 milliseconds before it is detected by PFC-7500 Series panels.
Only use detection devices that are rated for use with this delay.
11.4 Compatible 2-Wire Smoke Detectors
The table below lists detectors meeting the compatibility requirements for use with the Class B (Style A) zones on the
PFC-7500 Series fire panels. Do not mix detectors from different manufacturers on the same zone.
