Am5791B - LEGRAND 3440 Technical Sheet

Passive IR detector
Description
These devices are the simplified version of sensors item L/N/NT4611, item 675 02 and
item AM5791. They have a fixed level of sensitivity (6 metres).
Also in this case, the passive infrared detector is a volumetric detector with tilting lens,
sensitive to the movement of warm bodies.
The volume of the protected zone is divided into 14 beams distributed on 3 levels.
The detector works in two different ways: instantaneous or with impulse calculation, in
order to reduce the possibility of false alarms. It is available for installation in the high
sections of rooms, at heights between 1.2 and 2 metres.
The position of the lens should then be adjusted based on the characteristics of the room
to protect.
