Abstract

An electromechanical locking device comprising a locking member 30 such as a rotatable striker or locking bolt movable between locked and unlocked positions. An electromechnically, e.g. solenoid, driven deadlocking/blocking member 60 slidable between a blocking position obstructing the locking member and a non-blocking position wherein the lock member is freely movable into the unlocked position. The blocking member 60 has a first side having a first abutting surface 64 and a first groove 63 and a second, preferably, opposing side having a second groove 66 and a second abutting surface 67. The blocking member can be mounted in two different installation positions to convert it from a failsafe (power to lock) device to a fail secure (power to unlock) device. In the failsafe configuration in the de-energised state the first groove is aligned with the locking member permitting unlocking and in the energised position the blocking member is driven to the second position wherein the first blocking surface prevents unlocking movement. The blocking member 60 can be removed, rotated 180 degrees and re-inserted to convert it between modes to place the second groove and blocking surface in use.
