Winland TA-40 Powerless Operation for Controlled Climates


Temp°Alert® TA-40
Powerless Operation for Controlled Climates


For simple low cost protection from freezing in homes, mountain cabins, or any unattended building, the Temp°Alert® TA-40 will activate any hardwire or wireless alarm system if the temperature should fall below 39°F (4°C). The TA-40 offers positive protection and peace of mind to residential and business owners concerned about the risk of frost shattered pipes and the water damage that follows.


An added advantage of the TA-40 is the unit’s compact size which enables it to be installed in virtually any setting without being noticed. Why not provide your customers with total security by including reliable temperature protection in their security system?


Please Note: Not for use in cooler/freezer monitoring, instead choose an EnviroAlert® with probe. 




  • Will activate virtually an alarm panel, dialer or wireless alarm.
  • Normally closed (NC) dry contacts at temperatures above +39.5°F (+4.17°C).
  • Very small size for unobtrusive appearance.
  • No power required to operate.
