System Display When in Alarm
when the system goes into alarm the display immediately
selects the first channel that went into alarm to be the
current channel. Note Alarms take precedence over any
system faults. An Amber FAULT indicator appears in the
event of any panel faults as indicated above.
The number of
active alarms is
displayed. Use
the left and right
keys to select
between
channels in
alarm.
If beacons and sounders are connected using detector nodes then the sounders can be muted.
Note that if alarms are set as latching there are also options to try and reset just this channel or all
channels that are in alarm. To reset a latching alarm you must be below the alarm level.

set in the engineer menu
and is common in
ventilation applications to
introduce additional
hysteresis into a system.
