Model HS-10

Fire Closure Device
One-Temperature Manually Resettable

The HS-10 fire closure device employs a one-temperature, manually resettable, electric thermostat sensor to interrupt the electrical power to actuators used on fire/smoke dampers to permit the controlled closure of the dampers. The HS-10 is designed to replace the fusible link. The HS-10 permits testing of the damper closure by applying direct heat to the sensor’s disc or by physically depressing the disc from the inside of the damper sleeve. The damper can be reopened by manually resetting the sensor from the exterior side of the damper sleeve, once the disc has cooled down below its set temperature.
