This damper is installed in the pipe of ventilation system and air-conditioning system which need smoke prevention and fire prevention, and in the pipe of exhaust system.
1. Operation device is consisted of electric actuator with spring reset, and temperature controlled switch. At ordinary time, the electric actuator must be electrified to make damper at open condition, when in fire situation, the damper will be closed by the spring, thus act as the function of preventing fire and smoke. Usually this damper is used in difficult operation system and high automated level required system.
2. Damper opens through continuous power supply by Fire Service Center, DC 24V and close when power is off. If reset and start again, then new continuous power supply is needed.
3. Temperature control: temperature sensor works to make damper closed.
