The Temp Alert Temperature Switch can be used with all Sensaphone models to monitor air temperature from -30 to 130F (-34 to 54C). Simply determine the acceptable temperature limits for your application by adjusting the temperature limit arms. When the temperature exceeds the setting, the sensor triggers an alarm. The temp alert can be mounted to any wall or vertical surface. Multiple temp alerts may be wired in parallel to a single input. It requires no power for operation and mounts easily on any flat surface.
