Safety System With Photocells - Assa Abloy SL500 Manual

How to check side presence detector(s)
Side presence sensors can be used for example if higher door speed is required or for installations
in homes for elderly/disabled or childcare centres, to protect users from being struck by the doors
during their opening cycle. When a side presence sensor detects an obstacle the door operator will
not stop, but slow down the door movement to a safe speed. With this safe speed the door will try
to push the obstruction away, to ensure that the person passing through the door will not walk into
the door.
Walk into the detection field of the side presence sensor on one side. Activate the impulse on the
operator, the door shall not stop, but slow down to safe speed during the opening.
If you have a bi-parting (double) door then repeat the procedure above on the other side.

Safety system with photocells

Alternatively the safety system can incorporate presence photocells in the door opening. If an object
is breaking the infrared – – – – (invisible) beam between the photocell units, while the doors are
closing, the doors reverse immediately. The door will close when the object is removed.
