How it Works

Thermalarm alarm thermometers contain two electrical contacts that, when properly installed, will accurately indicate ambient temperatures and activate an alarm system when the temperature reaches either of the user-adjustable high or low settings.

Thermalarms provide years of reliable, trouble-free service at an affordable cost, thanks to their high-quality materials and simplicity of design.

Thermalarms are compatible with most popular alarm systems. They may also be used as a component in a simple alarm system constructed of a low voltage power source and an alerting device (such as a bell or buzzer) to activate the system in the event of a temperature problem.
