OPTEX FX-40D Superior Version Passive Infrared Detector
Product Description
FX-40D features ECO Technology (Environmental Compensation), which increase the sensor's resistance to all kinds of environmental disturbances. Logic built into the chip allows the sensor to recognize, discriminate and adjust for temperature changes within the sensor's environment. This technology also makes the unit less susceptible to false alarms due to RFI disturbances.
A Temperature Compensation Circuit increases detection capability under high temperature conditions where the background temperature is similar to that of the human body. It maintains a high level of false alarm protection while providing accurate detection by automatically adjusting its sensitivity according to the environmental temperature.
