DEVICE INTENDED USE
Application
Single-plane fire dampers type mcr FID B (square cross-section) may be used as:
cut-off fire dampers – mcr FID B/S
cut-off fire dampers for fire ventilation systems – mcr FID B/V
cut-off fire dampers for mixed fire ventilation systems – mcr FID B/M
transfer dampers – mcr FID B/T
relief dampers – mcr FID B/G
Caution:
Cut-off fire dampers for fire ventilation systems the mcr FID B/V and fire dampers for mixed fire ventilation
systems the mcr FID B/M, have one declaration of performance in accordance with the requirements of
law.
The marker -M and the word "mixed" used in the document are trademarks used by the manufacturer.
The construction and execution of the above dampers is the same regardless of the commercial mark.
The mcr FID B dampers have the MA feature (manual activate). This means that the damper
partition can change its position during a fire (the damper can open or close). The damper can be
operated without deteriorating its fire properties for 25 minutes
.
Dampers classified as "MA" can be used wherever a multi-stage fire scenario is required, wherever manual
control of the smoke exhaust system by authorized units is allowed during a fire (e.g. the need to
"manually" change the position of the damper partitions and " overrides "of the smoke exhaust system
automatically started in the wrong fire zone).
The dampers cannot be operated in systems exposed to dust, except for when they are included in a
special, individually developed programme of service and technical inspections.
