200mm Circular Single Blade Externally Resettable Combination Fire and Volume Control Damper.
The manual operation single blade fire damper with volume control facility has been designed specifically for installations where space is at a premium. The testing and resetting of the damper and thermal fuse external of the duct allows for ease of commissioning and maintenance. NB:Access panels may be required to comply with DW145 G.3.1.5.
The installation plate, with its engineered installation perforations, acts as a template to allow the marking of the fixing positions on the surface structure to which the plate will be affixed, allowing for a quick and efficient install
The volume control facility utilises the seven presets at 10° set points from fully open to 30° from the fully closed position.
The operating handle has been designed to be in line with the blade orientation thus providing an accurate guide to the blade set or released position. The manual damper continues to be a fully operational fire damper at these presets, and when released closed manually or through the melting of the thermal fuse meets the test criteria of EN 1366-2 as provided in the relevant test reports.
