6.4. ELECTRICAL CONNECTIONS
___________________________________________________
If the damper has control elements or other parts which need to be connected to the electrical grid, they should be
connected after correct mounting of fire damper in the wall. Below are showed connection diagrams and basic
electrical data of control-release mechanisms with which fire dampers mcr WIP PRO are supplied.
The thermal trigger is supplied with its baseplate for DIY installation. Fasten the thermal trigger with two sheet screws to
the device flange or the duct in a location clear of the fire damper blade rotation radius.
