Motor lock housing STEP 551

STEP 551 is a powerful and fast motor lock for door environments with high demands on security and evacuation. The technically designed hook bolt is extremely strong, fast and can withstand heavy loads. The lock housing is made of stainless steel and has a modern piston placement with the hook bolt placed in the center of the lock case. The lock can be placed in door environments with the absolute toughest burglary protection requirements. Certified in class 5 according to SSF 3522, and in Grade 7 according to SS-EN 14846. The control unit uses encrypted communication AES-128 for locking, unlocking and status indications. FreeDrive® technology disengages the motor in both locked and unlocked positions, which means that the lock can be used electrically and mechanically independently of each other. STEP 551 is without pressure drop and is well suited as a secure night lock with the motor lock placed as an additional lock.
