Setup Alarm
The Setup Alarm screen permits authorized users (based on password level) to
configure alarm behavior, such as the duration of alarms, methods of clearing
alarm condition, and how alarms are acknowledged.
Latch Alarm If enabled, causes the display of red ALARM on the
Home screen to remain, even if room pressurization
returns to NORMAL. Latch Alarm enabled requires that
an alarm event be acknowledged and that the pressure
returns to within the normal range. This is useful be-
cause it forces recognition that an alarm event occurred.
The alarm will still be on even if the pressure returns to
normal range. Only when the alarm is acknowledged will
alarming cease. When disabled, the alarm will be silenced
when the pressure returns to normal range without requir-
ing acknowledgement.
When a Latch Alarm occurs, the Home screen displays a
RESET button to the right of the Menu button. Press the
RESET button to acknowledge and reset the Latch Alarm
condition.
Alarm Delay Time between when the pressure went outside alarm
setpoints and when the unit goes into alarm mode. This is
useful in preventing false alarms. For example, if Alarm
Delay is set to 20 seconds, the staff has 20 seconds to
open a door, enter the room and close the door before
the alarm sounds (if audible alarms are enabled). Alarm
Delay also applies to alarms annunciated to a remote an-
nunciator via the SRCM Digital Output (hardware con-
figuration).
