14 Reference & Installation Manual
2.19 Fire Circuits
When a zone is programmed as a fire zone, the zone becomes normally open and requires an EOL resistor. If a line short occurs
or if the smoke detector becomes active, whether the system is armed or disarmed, the control panel will generate an alarm. If a
trouble occurs on a fire zone, the Fire Loop Trouble will appear in the keypad’s trouble display (see Trouble Display on page 60)
and the control panel can transmit the Fire Loop Trouble report, if programmed, in section [866].

+ [
ENTER] keys for three seconds. See Event Group # 6 in the Event Description list in the programming guide.
For 2-wire smoke detector installation, connect the 2-wire smoke detectors. If a line short occurs or the smoke detector
activates, whether the system is disarmed, the control panel will generate an alarm. If the line is open, the “Zone Fault”
trouble indication appears on the trouble display and the report code is sent to the monitoring station, if programmed.
