Different Principles For Detectors; Barrier Or Curtain Detector - Xtrails ADPRO PRO-18 Planning And Commissioning Manual

ADPRO Passive-Infrared (PIR) PRO Series by Xtralis

Operating and maintenance costs are comparatively low, because when a system is
properly planned and operated it needs very little maintenance.

Any seasonal adjustments or changes to use can easily be configured from a
distance, if a detector is, for instance, connected to an ADPRO video gateway via a
communications bus.

The camera body, modelled on a plastic housing, accords with protection standard IP
54, and optionally IP65 or even IP66.

The metal bracket to hold the detector, and all screws, are made of weather-resistant
stainless steel.

The PIR detector housing, and the plastic gas chamber (including terminal) that will
shortly become available, with its tamper-proof, concealed cable guide ('cable
management') are UV-stable and impact-resistant.

5.3.4 Different Principles for Detectors

Basically, detectors can be distinguished according to two main principles:

Barrier or curtain detectors

Surface or volumetric detectors
But to give a more precise solution for the requirements of different objects, there are finer
gradations between:

Curtain detectors with a larger aperture angle and medium nominal range

Curtain detectors with a small aperture angle and large nominal range

Volumetric detectors with a wide aperture angle and short nominal range

Volumetric detectors with a very wide aperture angle and medium nominal range

Volumetric detectors with a wide aperture angle large nominal range
Details of the nominal ranges, monitoring angles of aperture, and the monitoring ranges they
give, are given in the detector specifications in Chapter 16.

5.3.5 Barrier or Curtain Detector

Planning Notes
Depending on local conditions such as the length of property boundaries, distances to
obstacles (buildings, shrubs, containers, etc), the right choice of detector must take into
account:

Nominal range

Number of zones ('finger')

Monitoring angle of aperture
