The freezers and cryo stores temperatures are monitored by the 'Comark' system. You can access the comark monitoring system at the following web address:

Second floor and TDI

First floor labs

Within this website you can acknowledge alarms, change settings, add or remove probes, add or remove people etc etc. The inistruction manuals are also available on the website at the top of the monitoring screen.

The instruction manuals can also be found on the following link R500 Webview Help

Most people are given basic 'rights' on the site which means they can access freezers allocated to thier groups and acknowledge alarms. You will be sent an email with your log on details by your lab manager that you may need in the instance that you need to log on to the system, please keep this email for easy access if you ever need to log on to the system. If you are a comark user you will need to be able to VPN from your home computer for in case of an alarm. Then you can log on to the system and view what is occuring. This email will also contain a list of people who are responsible for each freezer and they should be called in the event of an alarm.

When a freezer is in alarm

There is a sequence of events that happen when a freezer goes into alarm. The first thing the comark system will do is ring a list of people that are allocated to a gateway. People are allocated spaces 1-5 and this is the order that the system will call. The first spot is occupied by the lab manager who will log on to Comark, see which freezer is in alarm and call the appropriate person.

If the person in position 1 does not pick up the call Comark will ring person in position 2, then 3 and so on.

If you pick up the call a recorded message will say 'this is a freezer alarm, press the hash key to acknowledge the alarm', by pressing the hash key you acknowledge the alarm on your phone but you must log on to the system to stop the alarm. However, if you log on to Comark and see that a freezer is in trouble you must ring the responsible person for that freezer. If you cannot contact the poeple allocated to the freezer you must go to the NDMRB, source the freezer and move the contents to the building spare. You must email the group to let them know that this has happened as the building spare is not temperature monitored.

If you are on the list that comark will call or you are on a list of responsible people for a freezer then you must let the lab manager know if you will be on leave so that arrangements can be made to cover you.

TDI Freezer map - quick reference

The TDI freezers have all been allocated an animal for quick and easy reference. This also allows anyone from outside the TDI to quickly identify a freezer and who to contact in the event of a breakdown. There is a list of contacts physically in the freezer room and each Comark user will have this information on an email that they wouldve previously been sent.


In the event of a breakdown you must contact the people allocated to each freezer in the order in which they are listed. If you cannot contact anyone from the list then contact the lab manager.

If you are the contact for a freezer you must deal with the failed freezer immediately. If there is no obvious reason for the drop in temperature or the freezer has completely failed, then the contents must be transferred in to the buildings freezer if there is room. If there is no room in the buildings freezer then you must transfer the contents to the TDI back up which is located on the second floor. Both of these back up freezers are NOT temperature monitored. Therefore you must put contact numbers on the front of the freezer which you are using and then contact the buildings team and/or the lab manager to let them know you are using the back up freezers.
