Alarms
The alarm system is designed to provide visual and audible
warning signals for both power failure and rise in temperature.
The alarm is equipped with a battery backup.
The power failure alarm system is activated only when
the key switch is turned to the Power Failure Alarm ON
position.
Low temperature, high temperature and door ajar alarms are
set to ON position by default as soon as the controller is
turned on. These cannot be turned off.
Default low and high alarm values are 2°C and 10°C. These
values may be adjusted, following instructions in section
Temperature Set point.
Note: There is no door open alarm on sliding door model.
The audible warning signal sounds when there is a power
failure, temperature alarm condition, or when the door is ajar
for more than 1 minute.
Alarm display codes for high temperature, low temperature,
sensor failure, door ajar are mentioned in Table 5.
