The fridges and freezers are under constant temperature monitoring. In order to avoid alarms, the monitoring has to be disconnected before the cleaning of 4°C fridges and the defrosting of -20°C/-80°C freezers (see [How to disable a Rmoni sensor](#how-to-disable-a-rmoni-sensor)).
**Please inform the Instrument Care team before every kind of maintenance by sending [a ticket](https://service.uni.lu/sp?id=sc_cat_item&sys_id=6ea39fdbdbec38105c72ef3c0b96196a&sysparm_category=af924f17dbac38105c72ef3c0b96194b) 24h before starting your maintenance**. They will disconnect the alarm on the monitoring until your appliance is back to its original temperature. Preferentially start your maintenance in the morning. When the maintenance is finished and the temperature is back to normal, reply on the open ticket to let them know you are done.

## How to disable a Rmoni sensor
## How to deactivate the alarm in Sensor4Lab
All the freezers are monitored via a software called Rmoni. To avoid any alarm due to the defrosting, the first step of the defrosting process is always to put the monitoring on hold. This step is needed for the cleaning of 4°C fridges and defrosting of -20°C/-80°C freezers.
