FAQs

The supplier lists this Pyro reference for FD30 applications, but that is not approval for an arbitrary fire-door replacement. The complete doorset's tested schedule must explicitly permit 4941813 and its matching components, with work carried out by a qualified fire-door specialist.

The supplier lists this exact reference as reversible/non-handed. Its latch setup and complete fire-doorset application must still follow a reference-bound installation instruction; no sibling handing rule should be substituted.

The selected unit has four remote deadbolts plus a latch-and-deadbolt centre case. Matching pockets, alignment and the complete doorset determine engagement and performance. Certified fire or security approval is not established by the bolt count alone.

The exact source describes a split 8mm spindle. Lever/pad suitability depends on the specified follower arrangement, spindle and furniture and, for fire use, the approved doorset schedule. Split operation alone does not clear every pad handle.
