Hi, new and learning to become a fire risk assessor . Im studying about fire doors and im just wondering. it a fire door has a "fire door keep shut" would you still be able to fix a the automatic door closers like the "Dorgard Fire Door Retainers" ? would you have to replace the sign with a new sign "fire door" or would it be acceptable to ? 

And also going off the subject a little, would the manufacture of the fire door be able to clarify if you can screw door closer devices like the above or would it make the fire door invalid ?

Thank you

Stephen

The sign should be changed as it doesn't need to be shut as a matter of routine as it now does it automatically and you don't want people forcing the door shut damaging the door or closer.

Strictly speaking you should ask the manufacturer although it's not likely to be an issue.

 

As you are learning be aware you can't just use any category of auto closer on any door - this guide to BS7273-4 will help https://www.fia.uk.com/static/uploaded/1de49d5a-0607-4c86-b25927f541bb03d0.pdf
