1 – e.g. a masonry wall
2 – A building element with fire resistance equal or higher to
the building envelope resistance
3 – mcr FID S/... p/P fire damper, BxH.
4 – A building element with fire resistance equal or higher to the building
envelope resistance. For example, a brick wall.

Installation of the mcr WIP fire damper as a multiple damper set (a set of 4)
Other configurations of the mcr WIP/… dampers modules can be made, consisting of two or more dampers, while
maintaining the minimum distances between the dampers according to the drawing above
6.4.
ELECTRICAL CONNECTIONS
Once a fire damper has been correctly installed, it is necessary to connect it to the electrical wiring system (using
the wiring system’s cables) if the fire damper is equipped with controls or other components that require such
connection. Shown below are the wiring diagrams and basic electrical data of the release and control mechanisms
supplied together with the mcr WIP type fire dampers.
Thermoelectric tripping device is supplied with a mounting plate for self-assembly. The tripping device shall be
fastened with two self-tapping screws to the flange of the fire damper, so as not to block the rotation of the blades.
