6.3.2 Temperature alarm delay
When the cabinet temperature is disturbed by opening the door, the temperature fluctuation can
inadvertently trigger a high temperature alarm. The TEMPERATURE ALARM DELAY,
programmable from 5 to 180 minutes, helps prevent false high temperature alarms by delaying
the high temperature alarm for a set period of time after the outer door is opened. If the freezer
temperature recovers to within the high and low temperature alarm settings during the set delay
period, no alarm will be triggered. If the freezer has not recovered within the set delay period, an
alarm will be triggered. The subsequent alarm can be muted (see Alarm mute and
acknowledgement on p. 23).
This programmable feature does not affect low temperature alarms, nor will it prevent an alarm in
the advent of a temperature fluctuation that is not the result of a door opening (for example, a
power failure).
6.3.3 Door open alarm delay
The DOOR OPEN ALARM DELAY, programmable from 1 to 10 minutes, provides the user with
an audible warning that the outer door has not been closed properly, or that the door is being held
open for a prolonged period of time. When the outer door is opened, a timer counts down the
programmed period of delay, after which the alarm is triggered if the door is still open.
6.3.4 Audible alarm mute
The AUDIBLE ALARM MUTE, programmable from 5 to 60 minutes, provides the user with a
means to delay the audible alarm from re-activating after an audible alarm has been muted.
When an audible alarm is activated, the alarm can be muted by pressing any directional key
when the main screen is displayed. The audible alarm will then be muted for the programmed
delay period before reactivating.
If the alarm condition clears before the delay period is over, the audible alarm will not re-activate
and the delay countdown will be cancelled.
6.3.5 Alarm socket delay
The ALARM SOCKET DELAY, programmable from 5 to 180 minutes, allows you to delay the
activation of the alarm monitoring socket during a temperature alarm.
