Standard Safety; Microprocessor For Precise Control; Safety System With Presence Sensors - Assa Abloy CMD User Manual

Note that more than one lock may be fitted.

Standard safety

To permit a safe passage between closing doors, the doors reverse immediately if an obstruction is
detected. They then resume their interrupted movement at low speed to check whether the obstruc-
tion has disappeared or not.
If an obstruction is detected while the door is opening, the doors stop immediately, and then close
after a time delay.

Microprocessor for precise control

The microprocessor has a routine for self-monitoring, which detects any interference or faulty signals
in door operation. If an input signal does not correspond to the preprogramming, the microprocessor
automatically takes necessary actions to ensure a safe operation.

Safety system with presence sensors

Usually the safety system incorporates presence sensors installed above the door opening. A presence
sensor detects an object in the doorway, while the doors are closing, the doors reverse immediately.
The doors will start to close when the object is removed.
