Vintage Whelen Engineering. Co. Safety Freeze Alarm Beacon Light manufactured in Deep River, CT in Very Good condition. Beacon light has been tested and works. Very minimal scratching, has been sitting untouched for 30 years in a basement. Comes with original box (unfortunately no instructional manual though).

This freeze alarm consists of an adjustable thermostat connected to a flashing unit. When the temperature falls below the setting, it will activate the lamp to flash.

Thanks for looking
