I utilize an electronic temperature monitoring system where all of my alarms are set and tested on a quarterly basis.  Do I also need to perform quarterly alarm checks on my refrigerators and freezers?  It seems redundant.  The manufacture instruction manual says to perform quarterly alarm checks on the unit itself.  I don't want to not follow manufacturer's instructions, but at the same time feel my electronic temperature monitoring system is better utilized for this purpose.

  My thinking would be if the electronic monitoring system would go down for some reason, do I know that my alarms will still work at the correct temperature?

FDA usually says to follow manufacturers instructions.
