STEP 352 is a motor lock developed with world-leading technology. It increases the intrusion security in perimeter locking and creates a secure locking around the clock, without you having to compromise with other requirements or the ease of use. The lock is adapted for high-frequency door environments with door automation and can handle several million openings! Certified in class 2A, 2B and 3 according to SSF 3522.
STEP 352 is part of the STEP 300 motor lock series. This motor lock is developed to ensure secure locking around the clock.
The lock is developed for high-frequency use and can handle several million openings, just as fast as an electric strike. In this way, it provides a unique opportunity to get higher security where it is needed, and thus get the right locking on vulnerable and important doors.
The lock can combine all requirements for evacuation, re-entry, fire resistance and door automation while at the same time giving the door environment a significantly higher intrusion security. STEP 352 is equipped with a strong hook bolt that really ensures that the door is locked.
STEP 352 is opened via the cylinder follower, meaning you can unlock both the hook bolt and the automatic latch bolt with a key from the exterior side or via thumb turn/emergency exit device on the interior side. This motor lock can therefore with advantage be placed in an alarmed evacuation door.
With STEP 352, you can also equip the door with a pull handle on the exterior side.
STEP 352 is equipped with STEPs unique automatic latch bolt.
When the door opens electrically, the automatic latch bolt can fold which enables the door to be opened with door automation. Directly after the door is opened, the automatic latch bolt extends out and anchors itself in its original position, functioning again as a classic latch bolt.
STEP 352 is therefore the obvious choise in door environments where you want increased accessibility.
Choose whether the lock should fit a right-hung or left-hung door.
The automatic latch bolt can handle a high preload of 80 kg, which ensures a very high operational reliability.
The lock has a double blocking, where the blocking of the hook bolt also is blocked by a latch. The latch position is read by an optical sensor so you can trust that it is really locked. The latch is completely protected from access and thus ensures protection against manipulation.
The FreeDrive® technology enables the locks motor and gearbox to disengages every time the door unlocks mechanically. This means that the wear minimizes when using lever handle, knob, keys or emergency exit device. Locks with FreeDrive® used together with STEP Exit on doors with emergency exits can therefore be used thousands of times every day.
Many door environments are today equipped with latch locks that can handle evacuation, re-entry, fire and accessibility requirements, but at the price of low intrusion security. It is about exterior and interior perimeter protection doors in thousands of apartment buildings, hospitals, treatment centers and correctional facilities to name a few.
With the STEP 352 motor lock, you don’t have to compromise on intrusion security. Instead, you can ensure a combination of all the requirements above in one and the same lock, and also place it in a door environment that is used with high frequency.
