Replacing intumescent seals

[John W]

I am replacing the intumescent seals on the firedoor frames of a small theatre. It seems when they were installed in 1997 the chippy cut bits out to accommodate the hinges, this cant be right. Do I need to relocate all the hinges to clear the channel for the strip or can I cut the strip either side of the hinges and fill the channel? The door sets came from Shapland, I can't find any data about them.

Most 30 min doors can be installed like this, it is only 60 and above where at lease one the strips must be continuous
