Door coordinators

The double-leaf fire doors should be well equipped with a device for coordinating these sheets according to the UNE EN 1158:2003 “Building hardware. Coordinator devices. Requirements and test methods.”

These mechanisms produce a time delay in the closing of one of the leaves, letting the other pass, so as to achieve a controlled and effective closure of the two sheets, with the help of door closers.

The CE marking is established by the Construction Products Directive 89/106/EEC, which defines a building  product as “any product manufactured for permanent incorporation in the works.”

There are devices, not just the mechanics of the image, but also electro mechanics. Moreover, the same door closers can do the role of selection and closing of closure, although the standard is the mechanical device of the image.
