Optex BX80N is a passive infrared detector which detects the infrared heat energy that is emitted by humans. It offers dual side adjustable detection range up to maximum 12m per side. Final detection range achieved at site shall depends on temperature.
How to use
BX80N is designed with Optex new concept – Boundary Gard. This PIR concept protects a building’s exterior by detecting intruders before an entry is attempted. In addition to signalling an alarm system, BX80N can create an audible local alarm sound to deter intruders before a break-in occurs.
After lens angle adjustment, the final reading range achieved at actual site depends on temperature of enviroment. BX80N detects temperature differences between moving target and background temperature. During hot afternoon sun, human body temperature has very small different to environment temperature. It is more difficult for BX80N to tell the difference of temperature therefore the reading range will become shorter. In late evening, human body temperature have bigger different compared to environment temperature therefore the reading range will become longer.
