Potter PFC-7500 Series - Manual (Page 16)

12.1 Description
The PFC-7500 Series panels can provide two programmable auxiliary Form C (SPDT) relays when equipped with plug-
in relays in sockets OUTPUT 1 and OUTPUT 2. Each relay is rated for 1 Amp at
30 VDC (allows .35 power factor).
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 Series boards.
The Form C relays can be operated by any of the functions listed below:
1) Activation by a zone condition 3) Fire alarm or Fire trouble
2) Communication Failure
Annunciator Outputs
13.1 Description
The PFC-7500 Series panels provide four programmable open collector annunciator outputs that can be programmed to
indicate the activity of the panel zones or conditions occurring on the system. Open collector outputs do not provide a voltage
but instead switch to ground voltage from another source. Each annunciator output is rated for 50mA at 30 VDC resistive.
Form C and Annunciator outputs operate together: The Form C outputs 1 and 2 are internally connected to the
Annunciator outputs 1 and 2. Any options assigned to Output 1 or 2 in the panel’s Output Options programming applies
to both outputs. While the Form C outputs each require a Plug-in Relay, the annunciator outputs work without the relays.
The Annunciator outputs can respond to any of the conditions listed below:
1) Activation by zone condition
2) Communication failure
3) Fire Alarm, Fire Trouble, or Supervisory
13.2 Harness Wiring
The Annunciator outputs are accessible by installing the Harness on the 4-pin header labeled J12. The output locations
are shown below:
Output Color Wire
1 Red 1
2 Yellow 2
3 Green 3
4 Black 4
Devices connected to the outputs must be located within the same room as the PFC-7500 Series panels.
Telephone RJ Connector
14.1 Description
Connect the panel to the public telephone network by installing RJ Cables between the panel’s J4 (MAIN) and J5
(BACKUP) connectors, and the RJ31X or RJ38X phone jacks on the 356 cable. The maximum line impedance is 100 Ohms.
14.2 FCC Registration
The PFC-7500 Series panels comply with FCC part 68 and are registered with the FCC.
Registration number: CCKUSA - 1SNM0 - AL - R
