The control unit ST500C uses encrypted communication OSDP AES-128 for locking, unlocking and status indications. It can handle up to two motor locks. These can be controlled individually or synchronized for connection to access control systems, alarms and central function.
With STEP 535, you have the ability to configure several different re-entry options through the control unit:
The re-entry function can be reset via a key, reset signal, or reset fire alarm.
The lock has a double blocking, where the hook bolts block also has a manipualtion protected barrier. The barrier’s position is monitored by an optical sensor, ensuring that it is indeed locked. The barrier is completely shielded from access, thus providing protection against tampering.
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.
Combine with the STEP Exit emergency exit device to create a safer evacuation route with unparalleled user-friendliness and, furthermore, to maximize the benefits of the FreeDrive® technology.
The FreeDrive® technology disconnects the motor and gearbox, meaning that they are never affected when the exit device’s lever is used. As a result, the impact on the motor and gearbox is minimized, even if the exit device is used thousands of times each day.
