Model HS-10-M

Fire Closure Device
One-Temperature Manually Resettable with Test Switch

The HS-10-M is a control switch and a fire closure device. It employs a momentary push button switch that permits cyclic testing at the damper location under normal conditions. It features a one-temperature, manually resettable electric thermostat sensor which replaces the fusible link and permits the controlled closure of the fire/smoke damper by interrupting the electrical power at a given temperature. The damper will close when the power is removed and will automatically re-open once power is restored.
