| Passive Infrared Vehicle Detector, ASIM by Xtralis Traffic Detectors |
| Model IR 301-303 |
| Operating Principle |
| The ASIM Passive Infrared (PIR) Detectors IR 301 and 303 are designed for
the detection of vehicles for the request and extension of the green phase in
traffic dependent intersection controls. They detect vehicles and other objects in its cone-shaped detection area by their movement and positive or negative temperature contrast against the background. In standard mode, the detector generates output pulses as long as movement of people or vehicles is detected within the field of view. When the movement stops, the output will reset. For more details see “Output Confi guration”. |
| Product Highlights |
| • Easy installation and maintenance • Very low power consumption • The spray proof, rugged housing of anodised aluminium protects the detector against the harshest environmental conditions. • Slightest positive or negative changes of thermal radiation caused by movements in the field of view are sufficient for detection. • The differential electronic circuit detects the movements of all kinds of moving objects. Temperature changes of the road surface are cancelled. • The precisely defi ned fi eld of view allows lane selective detection of vehicles of up to 30 m (IR 301) or 50 m (IR303) respectively. • A standard mounting U-shaped bar is supplied for quick, stable and versatile installation. • Passive detection of naturally existing temperature radiation eliminates interference between neighbouring units and potential health hazard. |

| Accessories |
| The integrated mounting bracket
allows for a stable and safe
installation on flat surfaces. It is
designed for easy mounting while
providing the necessary flexibility to
properly aim the detector to the target
area. For pole mounting we recommend one of the following accessories. |
| Mounting Brackets ZA P L1 / ZA V 201 | |
