Description
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.
Features and benefits:
- Easy to install.
- CE marked against the requirements of EN 15650.
- Classified in accordance with EN 13501-3.
- Fire tested to EN 1366-2.
- 120 minute installations for drywall partitions of minimum specification EI60, masonry walls and concrete floor slabs.
- No backfilling or sealing of apertures required.
- Hand operated or motorised, with on-site conversion between type.
- All installations are classified ‘i↔o’ meaning air is permitted to flow in either direction through the damper.
- Single handed test and set mechanism.
- UK patent application pending.
