Roof moisture detection is made with the unique sensor wire design; gutter moisture detection is made by the traditional sensing grid on the bottom of the SMGS-1 housing
The SMGS-1 housing sits directly in the gutter and the sensor wire is secured to the roof
The combination roof, Gutter detection system provides quick detection of potentially damaging roof, gutter icing conditions
As soon as moisture is detected, the SMGS-1 sends a signal to the SMMC-3 to energize de-icing cables
The SMGS-1 Sensor operates on low voltage provided by the SMMC-3 Control Panel and includes 3 m (10 ft) of wire for connection back to the SMMC-3 as well as mounting hardware
Connection wire may be extended up to 152.4 m (500 ft) with an appropriately rated 18-20 AWG 3-wire unshielded cable
