Integrated Safety; Safety System With Presence Sensors - Assa Abloy SL300 User Manual

Integrated 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.

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.
