Thermotech 302-AW-135

The Thermotech 302-AW-135 is an all-weather, rate-anticipation heat detector rated at 135 degrees F, built with a hermetically sealed housing and four wire leads so it can be installed indoors or outdoors without a special back box. Its rate-anticipation design holds the alarm trip point within roughly two to three degrees of the rated setpoint regardless of how fast or slowly the surrounding temperature rises, and the detector self-restores once conditions return to normal.

Key Features
