Hi 

Longshot this one but I'm looking for a number coded lock for both 30 min and 60 min doors, these doors aren't on fire escape routes but will be required as the only mechanism of keeping the door shut.

The blanks being utilised are from Flamebreak and the following is from the FOA both 30 and 60 mins are pretty much the same....

 

Any help would be greatly appreciated 

It will be necessary to contact the code-lock manufacturer or supplier and examine their specific evidence of fire resistance performance for their product when fitted to a fire door of the type that you intend to use. Generally, that will mean the door must have a solid timber-based core throughout, rather than tubeboard.
