FSD-TD Series - Features & Benefits

The majority of the FSD-TD product variants are covered by third party Loss Prevention Certification Board (LPCB) product certification. This represents both full BS EN ISO 9001 quality compliance and a guarantee that the products are fully representative of those actually tested.

Tested and certified installation variants of the FSD-TD are available to cover masonry walls, dry walls, batt walls and floors. These cover the majority of applications/supporting constructions that are required to maintain compartmentation and protect escape routes and areas with sleeping risk.

All BSB tested installation methods give at least a ES120 (E120S) classification, usually only limited by the wall construction used. This is extended to ES240 (E240S) when installed using a HEVAC frame in a masonry/blockwork floor or wall.

Sleeve and angle methods, HEVAC frame methods, angle frame methods, cleat and drop rod methods and batt infill methods are available.

Some rarer installation applications are covered by assessment/test information to BS 476-20/22.

Minimum size 100 x 100 (not adapted from a larger size by reducers) available for space saving.

Circular connection - base damper does not increase, thus saving space and transport volume.

Single section size 1000 x 1000, available from the smallest size up to this in millimetre increments.

Multi-section configurations are available to specific customer requirements, but will be subject to Building Control Authority approval.

No duct sleeve, again giving space savings over other models and savings on transport volume.

Standard construction is a fully welded galvanised steel case, which gives a casing leakage that complies with Class C ductwork leakage specifications.

Blades have folded safe-edges to aid site safety.

Galvanised mild steel, Ferritic (430) type 1.4016 or Austenitic (316) 1.4401 grade stainless steels for the blades and case are available for specific customer requirements.

All blade and motor connecting drives are removed from the airstream and are fully enclosed. This gives both increased free area through the damper and protection to the mechanisms.

Electrical Actuators (24VAC/DC, 230VAC,) have a less than 60 second motoring time. They have multi-position fitting and, being remote from the duct, allow space savings.

Pneumatic Actuator (5.6 bar) have a less than 3 second opening and closing time. They have multi-position fitting and, being remote from the duct, allow space savings.

All factory fitted actuators are tested prior to despatch (NOTE: The thermal fuse needs to be fitted/installed through the duct wall by the customer when the damper is installed).

Actuators may be supplied separately to the dampers for site fitting by others to suit customer specific requirements.

The FSD-TD range is fully compatible with the BSB range of smoke control panels, fire alarm systems, building management systems (BMS) and otherbespoke control systems.

The BSB FSD-TD has a strong and robust design to both meet the exacting fire testing requirements and be resilient to site handling. This is supported by sound production techniques which result in a quality product.

All the above, supported with BSB’s enviable delivery performance, provide an unbeatable combination.
