Features

  • 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
