NCA Series 400 - Single Blade Fire Dampers

The NCA Series 400 is designed to maintain compartmentation in buildings and locations where ductwork penetrates a fire barrier, to prevent fires spreading through ductwork. With their reduced leakage design, NCA Series 400 motorised leakage rated fire dampers make them suitable for areas requiring dampers with ‘ES’ classification.

The S400 fire damper is available in two variants:

S400A (motorised): Equipped with a Belimo BFL or BFN series actuator (24 V or 230 V) complete with 72°C thermal probe.

S400H (hand operated): Equipped with a mechanism permitting testing and resetting of the damper to be completed in seconds with one hand. The thermal link is externally replaceable and available in 68°C or 93°C variants.
