SECTION 8
– ALARMS
The incubators are equipped with an alarm system that constantly monitors temperature,
humidity, and CO
2
to ensure the user is notified if the cabinet goes into an alarm
condition. Notification occurs via a RED indicator LED and an audible alarm. Each
alarm condition has been factory programmed to minimize nuisance alarms while
maximizing warning time. The following table contains the alarm conditions being
checked, the factory default alarm range, the amount of time an alarm must be present
to occur (alarm delay), and the message that will be displayed on the individual system
controller.

In the event an alarm occurs, the master alarm indicator will illuminate and an audible
alarm will occur. To temporarily disable the audible alarm, toggle the alarm audible
enable switch to silence. When the alarm condition is corrected both the master alarm
indicator and the audible alarm will be disabled.
Each of the three controllers has their own alarm indicator. The small red LED labeled 3
will be illuminated. The green set-point will be replaced with an alarm message
indicating the alarm condition. Refer to the alarm table above for a description of the
alarm messages.
Changing Alarm Set-points
All alarm set-points were preset at the factory to minimize nuisance alarms that could be
created as a result of door openings. Alarm set-point defaults are shown in the alarm
table earlier in this section. However, alarm set-points can be changed based on
individual user requirements. Each of the controllers is programmed in the same
manner. Press the advance key on the control system that you are changing until either
A.LO1 or A.HI1 is displayed in green. The red displayed value is the deviation from the
set-point that will activate the alarm. Press the UP arrow to increase the deviation,
press the down arrow to decrease the deviation. Press the Infinity Key to exit.
