Ampac FireFinder PLUS - Monitored Outputs

Page 15
4.8.4 Monitored Outputs
Four independently monitored and controlled outputs (TB7) are provided and can be configured for a
variety of uses.
➢ Alarm Devices - activated when any of its four sounder groups is active. (AS7240.2 Clause
7.7 and 7.8). The output is turned off during an Alarm (sounder) disable or Alarm (sounder)
silence condition.
➢ ASE – (Australia Firefinder Plus Only)
➢ Fire/FARE – activated by alarm condition (AS7240.2 Clause 7.7 and 7.9.1). The output is
turned off during a FIRE disable condition.
➢ Ancillary - activated on device alarm conditions. The Output is turned off during an Ancillary
disable condition.
➢ Warning System - activated on evacuation and device alarm conditions. The output is
turned off during an Alarm (sounder) disable or Alarm (sounder) silence condition.
➢ Fault - activated on all fault conditions (AS7240.2 Clause 9.9). The output is turned off
during a FAULT disable condition.
➢ General Purpose – activated via the Configmanager “Function” programmed logic.
➢ External Alarm Devices - activated by an Alarm condition when a Point (Detector) has
been configured as Fire/FARE. (AS7240.2 Clause 7.7 and 7.8). The output is turned off by
the removal of the alarm condition – Silence Alarms followed by Reset.
These monitored switched outputs, supply a nominal 24VDC, at up to 1 Amperes. Monitoring is for
short, open and earth faults when the output is OFF.
The outputs have been designed to operate with a programmable EOL of 3K3Ω, 10KΩ 22KΩ or
Unmonitored (no EOL) the 10K EOL is the default.

Warning systems and sounders are connected to the Brigade / PSU Monitor Board as shown below. If
more sounders are required, the Sounder / Bell Control Board must be used.
