STEP 352 Motor lock
STEP 352 motor lock is developed with world-leading technology to increase intrusion resistance in perimeter protection and create secure locking around the clock. It can be placed in door environments that are high-frequently used and combine intrusion protection, evacuation, re-entry, fire and accessibility requirements.
Increases intrusion security around the clock
Thanks to its sturdy hook bolt, which anchors securely into the frame, you can trust that the door is truly locked, not just latched. The hook bolt engages after every passage, even during daytime use, delivering uninterrupted intrusion protection around the clock.
Certified for intrusion protection in class 2A, 2B and 3 acc. to SSF 3522.
Handles a very high opening frequency
STEP 352 is built to withstand millions of openings, just as fast as an electric strike.
With unique FreeDrive®
The FreeDrive® technology disengages the motor and gearbox every time the lock is mechanically opened. This minimizes wear when using a thumb turn, key or emergency exit device. Locks with FreeDrive® are therefore advantageously used together with STEP Exit in doors on evacuation routes, and can be used thousands of times every day.
Unique automatic latch bolt increases accessibility
Thanks to the unique automatic latch bolt, STEP 352 can be used with door automation and ensure accessibility requirements. When the door is opened electrically, the automatic latch bolt can be fold and thus enables opening with door automation. Immediately after the door is opened, the automatic latch bolt extends out and anchors itself in its position, functioning again as a classic latch bolt.
The automatic latch bolt can handle a high preload pressure up to 80 kg which ensures very high operational reliability.
Equip the door with a pull handle on the outside
The automatic latch bolt allows you to equip the door with a pull handle on the outside, as emergency override can be done using a key from the outside, in combination with evacuation acc. To EN 179 from the inside. The lock can therefore with advantage be used in alarmed escape routes.
For door environments with fire requirements
Certified in fire technical class E/EI120 acc. to EN 14846.
For door environments with evacuation requirements
