EDWARDS SYSTEMS TECHNOLOGY EST3 - System Timers

Introduction
1.14 EST3 System Operation Manual
Check-in active message
When a check-in active message is displayed, one or more
stations in the check-in group have not been activated during the
required time period. The check-in active messages may be
viewed in the monitor message queue to determine the location
of the event. Contact the late check-in station and determine the
problem.
Emergency active message
The emergency active message is displayed when a check-in
station is activated outside the check-in period. This is used to
signal an emergency condition such as a fall, etc. To determine
the location of the check-in station, view the event in the alarm
message queue.
Note: Emergency Active messages are placed in the alarm
message queue but the event does not place the panel into alarm.
System timers
The system has a number of optional timers that are required by
certain jurisdictions to comply with fire codes. Most of these
timer functions do not require operator action, however,
understanding the function of these optional timers (if enabled)
will improve your understanding of why the system functions as
it does.
Alarm silence/reset inhibit timer
The alarm silence/reset inhibit timer is used to guarantee that the
notification appliances will sound for the minimum specified
period. This timer effectively disables the alarm silence and
reset buttons for a predetermined period. While the timers are
active, pressing the alarm silence and reset buttons has no effect.
Notes
• Your system may be equipped with notification appliances
associated with the fire sprinkler system, which can not be
silenced.
• Visual notification appliances can be configured not to turn
off when the audible notification appliances are silenced.
Automatic alarm silence timer
The automatic alarm silence timer is used to automatically
silence the notification appliances after a preset period, if they
have not been silenced using the alarm silence button. Typical
timer settings silence the signals from 5 to 30 minutes after
operation.
