mcr FID S/S p/P, mcr FID S/S p/O - single-blade fire cut-off damper for comfort ventilation systems

mcr FID S/S p/P, mcr FID S/S p/O - single-blade fire cut-off damper for comfort ventilation systems

Fire resistance class: EI120(v_e h_o i↔o)S

Certificate of constancy of performance 1488-CPR-0422/W and 1396-CPR-0103.

Dampers certified for conformance with EN 15650.

Dampers are classified as per EN 13501-3 and tested according to EN 1366-2.

Declaration of performance 004-05-CPR-2015.

Optional EX making of dampers (as per ATEX directive) for applications in explosion hazard zones.

KDB ATEX 17.0616, EU Declaration of conformity 001-01-2017.

Cut-off dampers of fire resistance independent from direction of air flow and of installation side.

Dampers for rectangular and rounded ventilation ducts.

mcr FID S/S p/P, mcr FID S/S p/O cut-off dampers are designed for installation in general ventilation systems, at the point of penetration of these installations through building partitions.

During fire, they allow to maintain fire resistance of the building partition through which ventilation and air conditioning ducts run. They also prevent propagation of fire, smoke and fire gases to the safe part of the building.

When made for potentially explosive zones (EX variant), the dampers may operate in zone 1 (risk of explosion of gases inside and outside of ventilation ducts) and zone 21 (risk of explosion of dust outside ducts). The dampers conform to the requirements of group II category 2G and -/2D.

Apart from standard dimensions, dampers can be customized to any size within the specified ranges.

Control:

RST mechanism - thermal trigger 72^oC (optionally 95^oC) on partition, actuating spring, manual arming;
RST/WK1 mechanism - thermal trigger 74^oC (optionally 95^oC) on partition, actuating spring and limit switch, manual arming;
RST-KW1/S - integrated mechanism - thermal trigger 74^oC (optionally 95^oC), in the mechanism, actuating spring, manual arming;
RST-KW1/S/WK1 or WK2 mechanism – integrated mechanism - thermal trigger 74^oC (optionally 95^oC) in the mechanism, actuating spring, one or two limit switches, manual arming;
RST-KW1/24l mechanism – integrated mechanism - thermal trigger 74^oC (optionally 95^oC) in the mechanism, actuating spring, one or two limit switches, electromagnetic trigger responding to current impulse, U=24V DC manual arming;
RST-KW1/24P mechanism – integrated mechanism (thermal trigger 74^oC (optionally 95^oC) in the mechanism, actuating spring, one or two limit switches, electromagnetic trigger responding to power decay, U-24V DC, manual arming;
Belimo type mechanism – actuators series with return spring and thermoelectric trigger (BFL, BFN, EXBF series).

The use of MP230/24 element enables the powering/triggering of KW1 mechanism with 230V AC voltage.

Making variants:

mcr FID S/S [BFL…-T, BFN…-T, BF…-T, EXBF] – fire cut-off damper for ventilation ducts, with electric actuator with return spring with thermoelectric trigger - closing and opening of damper using actuator
mcr FID S/S [RST] – fire cut-off damper for ventilation ducts with spring actuator and thermal activator
mcr FID S/S [RST/KW1] – fire cut-off duct for ventilation ducts with spring actuator with integrated thermal activator; electromagnetic activator and limit switches available optionally

Additional equipment:

WK1 – limit switch (closed barrier signal)
WK2 – limit switch ( damper open/shut signal)

mcr FID S/S dampers can be used as pressure-relief dampers in gas extinguishing systems; in this case they are equipped with actuators without thermoelectric or thermal activators.
