Passive IR detector
Description
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.
It is also possible to change the sensitivity threshold, and to generate auxiliary functions
when the system is disarmed.
