Operation
The operating principle and behaviour of the mcr FID PRO single-plane fire dampers depends on the version and
use:
automatically – by actuation of the thermoelectric release
manually – by pressing the control button on the thermoelectric release
remotely – by actuation of the axial electric actuator with a return spring as the supply voltage
disappears
automatically – by actuation of the thermal release and the power spring
The structure of the system equipped with an air diffuser enables the regulation of efficiency during normal operation
of the device (setting the gap between the body of the mechanism and the valve plug). The adjustment is made by
rotating the plug around the damper axis.
Release and control mechanisms
A release and control mechanism for the mcr FIND WING damper can be:
An RST type mechanism composed of a drive spring and a fuse release
Optionally, there is a possibility to equip the damper with WK1 limit switches that signal the damper operation status
(open/closed).
