Reset Jumper J9
15.1
Description
There is a reset jumper located at the top right of the panel circuit board labeled RESET. Momentarily shorting the metal wires
of the jumper with a screwdriver resets the microprocessor of the PFC-7500 Series panels to enter the internal Programmer.
Reset the panel while the system is operational (for example, during a service call) without powering down the system.
After resetting the panel for programming, begin within 30 minutes. If longer than 30 minutes, reset the panel again.
Silence/Reset Button
16.1
Silence/Reset Button
The PFC-7500 Series panels each contain a mechanical push button located on the top center of the printed circuit board
that allows authorized users to silence alarm bells or sirens and reset latched detection devices.
After pressing the button, the panel silences the Bell output (PFC-7501 terminal 5) and momentarily drops power to
the auxiliary output (PFC-7501 terminal 6), the TAM Trouble Annunciator Module, and zones 2 to 5 (both panels).
Additionally, any Fire or Supervisory event displays at the keypads are also cleared. A 2-pin reset header (J13) is also
provided for use with keyswitches.
16.2
Bell Circuit Monitor
The PFC-7501 panel contains a bell monitor input (J14) that can be connected to the trouble contacts of the SNM
Notification Circuit Module. When the 2-pin header is shorted via the notification module, the Bell Circuit Monitor is in
a restored condition. When the trouble contacts open, a bell circuit trouble is indicated. The PFC-7501 is shipped from
the factory with a shorting clip on the 2-pin header to indicate a restored condition. A harness is used to connect the J14
Bell Circuit Monitor to the trouble contacts of the SNM Notification Circuit Module.
Dual Phone Line Connectors
17.1
Description
The PFC-7500 Series panels contain built-in dual phone line capability that allows the panel to monitor two phone
lines, indicate a phone line failure, and switch to the alternate phone line to communicate alarm and system reports to
a central station.
Before sending a report, the panel verifies whether the main phone line is working. If not, the panel sends the report over
the backup phone line. An integrated phone line monitor circuit continually tests the phone lines and indicates a trouble
condition on the line after 90 seconds. If the phone line restores and is good for 90 seconds, the panel ends the phone line
trouble indication.
The maximum line impedance is 100 Ohms.
