ACCESSORIES AND PRODUCT MODELS Actuators Pneumatic, AT100 (rotating actuator), P0 Belimo BF 24-T-2 HL, operating voltage AC/DC 24 V (fuse: 72 °C, includes limit switch), B1 Belimo BF 230-T-2 HL, operating voltage AC 230 V (fuse: 72 °C, includes limit switch), B2 ACCESSORIES The fire damper can be equipped with a bipolar limit switch, which indicates the closing of the shut-off blade. The limit switch has potential-free contacts (no=normally open and nc=normally closed), which can be used to control other fire dampers equipped with an electric release (e.g., triggering an alarm in the fire suppression...

FDS - Multi-blade-type Fire Damper for Rectangular and Circular Ducts Function The FDS is a rectangular fire damper, which prevents fire and smoke from spreading in ventilation ducts. Approved fire resistance classes are (EN 1366-2): ■ Ceilings: ES 60 ■ Walls: ES60, E90 (both concrete/masonry and lightweight walls) The fire damper is equipped with either an electrical or pneumatic actuator. Under all options, a fuse responds to a rise in temperature, causing a spring-return blade to close. Alternatively, the damper may be released by a system using an electric motor or using solenoids with a...

Servicing To ensure proper operation of the fire dampers, they should be inspected regularly. It is recommended that the fire damper be connected to automatic control and testing system MSH (24-V system). Dampers not connected to an automatic testing system shall be tested periodically. The minimum recommended inspection period is one year or according to building code. An inspection opening shall be installed in the proximity of the fire damper as indicated in the building code (not part of the product). Upon failure during testing of the fire damper, maintenance service shall be ordered from...
