Motor lock ST552 with Control unit ST500C

STEP 552 is a unique motor lock for door environments with automatic door systems. With STEP 552, you now have the opportunity to combine strength and burglary protection with accessibility requirements or requirements for automatic door systems – all in one powerful motor lock! STEP 552 has exactly the same great features and technologies as STEP 550. The difference between the two motor locks is that STEP 552 has a uniquely designed automatic piston. When the door is opened electrically, the automatic piston can fold, thus enabling opening with automatic door systems. Immediately after the door is opened, the automatic piston extends, locks into position and functions just like a regular deadbolt again.

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.

Motor lock ST552, Control unit ST500C, Drill protection ST1199, Adapter cable ST0917 0.2m and screw and magnet set ST1192.
