DRS-30

Overview

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 allows for damper testing per all NFPA specifications. The damper will close once power is removed from the DRS-30 and will automatically reopen once power is restored. The DRS-30 is factory equipped with an indicator switch package that employs an in-jamb assembly plate consisting of two single pole, double throw micro switches to provide full open and full closed blade indication from a remote location. The indicator switch package is factory installed directly to a damper blade.
