  Natural Smoke Vents
Optional Features
 


Control Options

Control Options


Bilco controls and accessories are designed to work effectively with the range of natural smoke ventilators and roof hatches. The OS2 control unit can be a stand-alone management system - in its own right, or it can be integrated into a fully networked fire alarm or BMS system. In the event of a fire, if the mains electrical supply to the building is cut the OS2 offers a failsafe option as it incorporates a backup battery system to ensure the natural smoke vents will still open. Special control units for unique applications can also be manufactured.

Base flanges of all Bilco roof hatches and smoke vents can be fabricated with built-in configurations for most brands of metal building roof panels.
