Abstract

Defines performance requirements and test methods for a thief-resistant mechanically operated single-point lock assembly (including locking plates, fixing screws, fitting instructions, cylinders and protective furniture, where appropriate) that: a) incorporates a lock conforming to BS EN 12209:2016 that, under normal conditions, can be unlocked from the inside without the use of a key, thereby allowing keyless egress; b) can be changed to a secure (no egress) mode by a secondary positive locking action; and c) is used in doors, window doors and entrance doors in buildings.
