Standard product features
Hold/ release mechanism:
Patented Thermolatch® II positive hold/ release mechanism, which ensures reliable vent operation when a fire occurs and prevents inadvertent opening of the covers caused by wind, building vibrations or other factors.
The latch is equipped with a 74°C fusible link for automatic operation. In the event of a fire, heat breaks the fusible link, allowing powerful lifting mechanisms to open the vent covers instantaneously.
Pull handles are provided for interior or exterior manual operation and heavy duty shock absorbers ensure smooth opening and eliminate the possibility of operational, roofing or structural damage
The vents carry an STC-45 and OITC-37 sound rating and are suitable for concert halls, theatres and other applications.
Available in eight standard sizes, consult with Bilco UK for non standard sizes.
