Lock fitted on existing fire door

[phil_mc]

At my work place an approved contractor (for fire wall penetrations) has installed a digi lock in to a fire door.

Am I right in saying that as there has been modifications to the fire door I will need a certificate for the integrity of this door now it has has holes drilled in it.

Yes, especially as they don't from your description appear to be approved for fire doors. The integrity of the door could be affected, also depending on the situation the door might not meet exit fastening standards.
