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 51) and the control panel can transmit the Fire Loop Trouble report, if programmed, in section [866].
