2.3.8 Releasing: Fast Release
Modules or detectors assigned to operate as a Fast Release function energize the releasing device
without performing the delay.
2.3.9 Releasing: Halt
Modules assigned to operate as a Halt function are able to interrupt the releasing delay timer, thus
preventing energization of the releasing device. Restoring the halt input does not allow the delay timer to
restart; the releasing sequence remains halted. The halt function has no effect if it is activated after the
delay time has expired.. The halt can only be cleared by resetting the panel.
2.3.10 Releasing: Abort
Modules assigned to operate as an Abort function are able to stop the delay timer when it reaches 10
seconds, thus preventing energization of the releasing device. Restoring the abort input allows the delay
timer to restart. Subsequent activation of the abort input will again stop the timer. The Abort function has
no effect if the delay timer has timed out.
2.4 User control interface
System control and programming can be done through the LCD annunciator on the panel. The main
status display is an LCD screen with 8 line by 20 character text capability. Five system LEDs indicate
alarm (red), alarm silence (red), supervisory alarm (red), trouble (yellow), and AC power (green). Ten
zones of programmable alarm and trouble LEDs are located on the right hand side of the annunciator. A
piezoelectric sounder provides audible annunciation of off-normal indications. LCD remote annunciators
are similar and provide the same functionality as the panel’s local LCD annunciator.
Security is provided by a locking door or requiring activation of a keyswitch for most annunciator
commands. Maintenance and programming functions are further protected by passwords.
2.4.1 Resets
There are three types of resets available.
Fast reset
