[Nhcoll-l] Alarms on freezers- particularly ultracolds/ULT

Tue Aug 1 13:34:14 EDT 2023

Hi Janaki

We have our ultracolds and cryo dewars monitored by ADT/TYCO/Johnson Controls (they have been buying each other out so frequently I cannot keep them straight 😊) through a phone based panel.  We have 3 ultracolds and various zones associated with three liquid nitrogen dewars along with room temperature alarms and oxygen monitors all hooked up the same system.  When  one of the zones trips, due to high temperature or some other alarm event, we have a call tree that ADT/TYCO/Johnson Controls calls to alert us.  They will keep calling until someone picks up the call and responds to the alarm.  It is a very effective system but requires some investment in the necessary infrastructure to run it.  You could reach out to ADT/TYCO/Johnson Controls to get a quote for installation.

Hope that helps.  Happy to provide more details if needed.

Hello everyone,

Recently our university risk management has implemented protocol for the management of temperature controlled units, (probably due to insurance losses). One requirement is to have continuous monitoring systems that reports to a phone number/email if in alarm. While some of our units have audible alarms they don’t all call/email to someone externally. Further, most of our units are not currently (nor optionally) hardwired and monitored by University facilities. So we must come up with a system.

As we have a system for room temp and RH on collections rooms, this is yet another system to monitor. Would be great if all could be together, and sounds if some companies are moving that direction, like Conserv. However they do not have sensors appropriate for ultracolds/ULTs. We turned to InTemp, but find their gateway system less than ideal due to building characteristics  (re: thick walls) , that would require and almost 1:1 ratio  datalogger:gateway. Further one has to access the website, not the app upon receiving an alarm, so not terribly user friendly.

I wonder what others are using for their temp controlled units specifically ultracolds. Additionally, what parameters do you set for alarm and recording period (e.g. every 15 mins).
Thanks in advance.
