Model DRS-30 fire closure device with indicator switch package two-temperature manually resettable

Application

The DRS-30 fire closure device employs a two-temperature, manually resettable, electric thermostat sensor to interrupt the electrical power to actuators used on fire/smoke dampers. The DRS-30 permits testing of the damper closure by applying direct heat to the one or both of the sensor's discs or by physically depressing one of the discs from the inside of the damper sleeve.
