Setup Alarm
The Setup Alarm screen permits authorized users (based on password level) to con-
gure alarm behavior, such as the duration of alarms, methods of clearing the alarm
condition, and how alarms are acknowledged. It also sets the room mode to positive,
negative or neutral room.
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 because
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
requiring 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 annunciator via the SRCM
Digital Output (hardware conguration).
Set Time &
Date Screen
The Set Time & Date tab is used for setting the time and date of the SRCM. This time
and date is used to time stamp the event log. See Event Log Section.
Note: If power is lost to the unit, the time, and date need to be reset. If BACnet is used and is connected
to the network, the time and date will automatically be retrieved.
The date format is DD-MM-YYYY.
