Why is it important to keep open automatic self-closing fire doors by keeping them stuck to the walls by their magnets?

It's purely a convenience factor - for use in high traffic areas where the doors being closed would hinder circulation leading to the doors being wedged or damaged (the later particularly where trolleys of goods are pushed through).

The hold opens will ensure the doors can always shut when they need to be.
