SmartSense is designed to help protect against excessive gas flows, gas-related fires, and even explosions, and its dual-sensing technology sets new industry standards for ensuring residential gas appliance connection safety. It features an internal valve mechanism that automatically reduces gas flow in the event of a dangerous downstream gas line rupture. Gas flow to the in-home appliance is thereby restricted until an upstream manual shutoff valve is closed or the gas leak is repaired. Once fixed, SmartSense automatically resets, restoring normal gas flow. It also includes thermal shutoff capabilities; when exposed to temperatures between 350°F. and 425°F. it terminates gas flow to minimize or prevent damage within the home. Easily installed and remains compatible with modern residential gas appliances. Both CSA design-certified and California DSA-listed, the device can be mounted either horizontally or vertically with gas appliances. Dormont.
