Smoke Dampers


Enter the code shown above
* Required



All smoke detectors require factory installed actuators, either electric or pneumatic.  They are controlled by a smoke or heat detector signal, fire alarm or other building control system.  

Smoke dampers are qualified under UL Standard 555S, Leakage Rated Dampers for Use in Smoke Control Systems.  Lau smoke detectors are always supplied with the appropriate factory mounted actuator and UL label.  UL555S requires all smoke dampers to be rated for operation with an approved actuator at a minimum airflow velocity of 2,000 fpm when open, and against a minimum pressure of 4 inches w.g. during closure.  Smoke dampers should be specified based on the conditions they will be exposed to in their application.
