SECTION 8 – ALARMS
Alarm System Overview
The chamber control system is equipped with an alarm system that constantly monitors
temperature, and humidity (on humidified models) to ensure the user is notified if the
cabinet goes into an alarm condition. Notification occurs via a RED indicator light and
an buzzer. 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.
Alarm Description Alarm
Deviation
Alarm Delay Alarm Message
Temp higher than Set-point +1.0  C 15 minutes Temp Controller – AL.h1
Temp lower than Set-point -1.0  C 15 minutes Temp Controller – AL.L1
RH higher than Set-point +5% RH 15 minutes RH Controller – AL.h1
RH lower than Set-point -5% RH 15 minutes RH Controller – AL.L1
In the event an alarm occurs, the 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 alarm indicator and the
audible alarm will be disabled. Return the alarm switch to audible.
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 are 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.
