The AT-FSD Series Fire Damper has been designed for use above protective doorways and extended fire separations, often within ceiling voids, to allow the movement of air, Typically between the stairwell to the lobby and is intended as an unducted installation.

The optional purpose designed Easy Fix™ non-vision grille provides a discrete appearance for the complete solution.

Requiring access from one side of the fire separation wall only, the damper when installed maintains fire compartmentation in the event of a fire.

The LD and LDN Series Smoke Control Dampers have been designed and tested (EN1366-10) for smoke evacuation and control within lobbies to maintain conditions in the common escape routes in the event of fire and are installed within smoke shafts constructed in either dry wall or masonry/concrete.

LD Series Dampers are designed to work with fan powered extract systems, pulling air through the damper and into the extract shaft.

LDN Series Dampers are designed for natural (stack effect) ventilation which requires a minimum area of 1.5m2 to comply with current standards and Approved Document B specification.

Both the damper and sleeve have visible internal surfaces with a matt black finish.

Both LD and LDN Dampers are supplied with a matched decorative grille that limits visibility to the rear damper whilst proving good free area satisfying both engineering and architectural requirements.

The Easy Fix™ grilles are affixed with supplied concealed matching fixings and form part of the fully tested solution.

Volume pricing available.

The ACP Addressable Control System has been specifically designed and developed for the control, monitoring and operation of connected ventilation damper systems and includes interface functions for Fans & BMS systems along with standard programmable inputs/Outputs which can be setup to meet specific project requirements.

The ACP focusses on life safety systems, for controlling Fire/Smoke damper systems, with programmable “Cause and Effect” to suit specific project requirements, but can be programmed to suit a number of applications as required.

Standard sizes range from ACP50 through to ACP350 offering flexibility to suit system sizes up to 350 individual Damper actuation points, either 24V or 230V and incorporates layered security access through the inbuilt TFT touch screen interface, all encased in a steel enclosure with hinged lockable glass fronted door.

All ACP panels are supplied pre-programed to suit individual Project “Cause & Effect”, reducing on site commissioning time.

To complement THE ACP Panel and give robust network communication between the ACP Panel and remote dampers, a range of purpose designed Addressable Dampers Modules are available (ADM) to ensure secure and safe communications.
