Vimpex Ltd, Europe’s independent manufacturer of fire alarm ancillaries, has added a Fire Door Coordinator - which ensures that a pair of self-closing fire doors will always close in the correct sequence, enabling each door leaf to shut fully, and help to maintain the fire integrity of the doors - to its door holder product range.
If double fire doors don’t close in the correct sequence they will not close in the middle and leave a gap for dangerous smoke and gases to pass through.
