The FG series safety switches with separate actuator with lock are not only proven interlocking systems with lock acc. to EN ISO 14119. In versions with option -V70V90, they comply with standards EN 81-20 and EN 81-50.
They can therefore be used as locking switches for hinged and sliding doors in passenger and goods lifts.
If attached to a landing or cabin door, the door can only be opened if the solenoid in the interior of the device is activated, so that the actuator located in the head can be unlocked.
