Normally closed locks are most often used in access control systems, because they do not require power in the closed position and remain locked in case of power loss. To guarantee the opening in an emergency, the lock cylinder can be opened with a key from the outside or with a key or a thumbscrew from the inside. Normally closed locks are used for office and warehouse doors.
PERCo-LBP85.1 lock has a unique construction, allowing control cable installation through the strike plate in the door frame and not through the whole door leaf. This makes installation easier and provides aesthetically pleasing exterior of the door without using adaptors.
There are two types of strike plates made by PERCo which can be used for profile doors of different manufacturers ("Petralyum", "Agrisovgaz", "ALUTECH", "NORDPROF" etc); the strike plate type is chosen by a customer at the time of order.
The strike plate PERCo-BP1 is used for installation in the following profile doors: door leafs T34, T53, T81, T85 and the door frame T72-14 (manufactured by "Petralyum" LLC) or equivalent dimensionally.
The strike plate PERCo-BP2 is used for installation in the following profile doors: door leafs AGS68_6863, AGS50_5213 and door frames AGS68_6864, AGS50_5215 (manufactured by "Agrisovgaz" LLC) or equivalent dimensionally.
