[Nhcoll-l] Monitoring system for -80°C freezer

[Bentley, Andrew Charles]

Gabi

Here at the BI we have three -80 chest freezers (all supplied by Thermo Fisher) along with our three liquid nitrogen dewars and they are all connected to a Johnson Controls (formerly TYCO, formerly ADT) alarm system using the provided connection points at the rear of the freezer.  This monitors high temperature (above -50°F) and power failure signals and then automatically calls a call lost we have set up in the system with both home and work numbers for 7 or 8 key personnel associated with the resources.  They continue to call until they reach a physical person who can respond to the alarm and check up afterwards to ensure that all is back to normal.  The liquid nitrogen dewars also have 4 alarms - high temp, low level, high level and battery backup that function similarly.  We also have an oxygen sensor in the Genetic Resources Facility connected to the same system.  This gives us 19 "zones" that are monitored across the facility.

Besides the company takeovers that have happened and associated changes required we have been very happy with the system we have in place and it has never failed us in cases of minor emergencies (power failures, freezer failure, LN2 supply tanks empty).

Happy to provide more information if it would be helpful.

Andy

Hi everyone,



If you have a -80°C freezer at your institution, which monitoring system (temp., power outage, etc.)  are you using and would you recommend it?



Please feel free to contact me directly.



Thanks!
