The lobby damper assembly consists of two parts. The main damper with its own sleeved casing allows the main damper assembly to be fully recessed fitted Belimo on/off actuator to drive the damper blades from the normally closed position to the fully open position on receipt of a signal from the global fire detection system. All internal surfaces are spray-painted black to allow this product to be discreet behind the easy-fit grille.
The grille has been designed to maximise the airflow while preventing interference with the damper vertical blades. The grille is affixed to the damper sleeve via six concealed colour-matched fixings. RAL 9010 white is offered as a neutral standard colour with other RAL colours to order.
The damper and grille assembly will have the damper typically closed in normal operation and will open to vent smoke and toxic gases that are generated in a fire condition on the level of the fire. The damper responds to a signal received via the smoke and fire detection system.
LD Dampers on all other levels remain closed, thus preventing the spread of fire from riser on those levels. The low leakage characteristics of these dampers maximise the riser extraction design performance

Nearly three years since the Hackitt Report’s publishing, the construction industry has been subjected to gradual changes by introducing regulations. However, the industry will likely face more changes to the legislature.
Over the last few years, the fire safety and smoke ventilation industry has been experiencing shifting legislature resulting in changes to designing, installing and maintaining fire safety systems. Therefore, it is critical that in order for your projects to remain compliant, that you understand these shifting regulations.
