Detector Placement (Typical Design Recommendation); Simple Monitoring Of An Enclosure With A Simple Boundary - Xtrails ADPRO PRO-18 Planning And Commissioning Manual

Planning and Commissioning Manual
To avoid water ingress and condensation inside the housing a special membrane is
integrated into the housing. Condensation can happen e.g. when on a very hot sunny day
suddenly a severe weather with hail and rain cools down the air very quickly.
The following IP65-rated PIR detectors are available as part of the ADPRO PRO range:

PRO-18H/IP65

PRO-18WH/IP65

PRO-18WIS

PRO-45H/IP65

PRO-45DH/IP65

PRO-85H/IP65

PRO-100H-IP65

PRO-100HIS
The following IP66-rated PIR detectors are available as part of the ADPRO PRO range:

PRO-85H/IP66

PRO-100H-IP66
5.4 Detector Placement (Typical Design
Recommendation)
For Passive Infrared Perimeter Intrusion Detecion Systems (PIR-PIDS) it is recommended to
terminate the detection area with a fence or any artificial barrier so as to avoid receiving
readings caused by the detector's nominal range and overlength.
The figure shows the detector's over-length and how the detection area is terminated so as
not to detect unnecessary movement; thus, reduce the false alarm rate.
The distance at which to terminate the detection area depends on the detector's model.

5.4.1 Simple Monitoring of an Enclosure with a Simple Boundary

5.4.1.1 Requirements
Monitoring of a higher fence surmounted by barbed wire.
The inner area remains unmonitored. Each alarm from a detector leads to an alarm or a
camera circuit.

NOTE!
Special care has to be taken to the cable glands. To avoid water
ingress through the unused cable gland (the upper one in the image) it
shall be ensured that the sealing blinding is correctly inserted.
