Controller Parameter Settings - Thermo Scientific TSG Series Installation And Operation Manual

Alarm Silencing
To mute the power fail alarm, change the key-switch to Power
ON position. The power fail alarm will not be audible but the
Red LED will be displayed on the control panel.
The high temperature, low temperature, sensor failure and
door ajar alarms can be silenced by pressing any key on the
controller.
When the alarm is active, the alarm code flashes alternately
with the temperature and the alarm symbol.
Once the alarm is silenced, the code stops flashing but the
temperature and the alarm symbol is still displayed.
