The FX-40 Series Indoor Wired Passive Infrared Detector from Optex is designed to provide stable and reliable detection in hostile environments. The accurate and reliable detection pattern maintains its sensitivity throughout the detection area even in high temperature or low contrast environments.

Multi-Focus Optics
The accurate and reliable detection pattern maintains its sensitivity throughout the entire detection area even in high temperature or low contrast environments. Multi-Focus Optics create an extremely high vertical zone density. These tall zones capture the entire body mass and enable detection of even the smallest temperature contrast against the temperature of the background. In addition, the vertical detection density has been improved to take into account dead zones created by furniture or partitions.
Sealed Optics
Prevents drafts and small insects from getting on to the pyroelectric element. This practically eliminates the chance of false alarm due to such causes since the pyro is sealed with the inside molding of the housing cover.
Hard & Durable Spherical Lens
It is designed to collect IR energy from the detection area and focus it directly onto the pyro. This lens design helps in obtaining sharp detection as no bending is required.
Look Down Zone
The Look Down Zone creates greatly improved vertical sensitivity.
False Alarm Protection
Offers RFI protection (no alarm at 20V/m from 100 MHz to 1 GHz) and temperature protection (no alarm during temperature changes from -4 to 122°F (-20 to 50°C).
ECO Technology
The detector features ECO technology that is designed to increase the sensor's resistance to all kinds of environmental disturbances. The logic is built into the chip that allows the sensor to recognize, discriminate, and adjust to the temperature changes within the sensor's environment. This technology also makes the unit less susceptible to false alarms due to RFI disturbances.
Temperature Compensation Circuit
The 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.
Additional Features
Features easy wiring knockouts, spare terminal, wide wiring space, wiring guide, LED on/off switch, improved EMI, tamper switch, and selectable pulse count of 2 or 4.
