The Optex WNX-40IX Wireless PIR Motion Detector is a pet-friendly sensor that is designed for use with Interlogix/GE and Qolsys Alarm Panels. The device offers a coverage area of up to 40 by 40 feet. It can alternatively provide a 60 by 6 foot coverage area by using an optional FL-60N lens.
The device works by taking a base reading of the infrared (IR) energy in the area. If any movement occurs, there will be a change in infrared energy. The change must be large enough to activate the motion sensor, as a user would not want any false alarms to occur. When the sensor detects a change in IR energy, the Optex WNX-40IX will then send an alert to the security system to let it know of the situation. The system will then respond according to the programming settings.
The WNX-40IX offers many features that are designed to actively reduce any false alarms. One way is with OPTEX Quad Zone Logic. This has the sensor distinguish between humans and other sources of motion, like ceiling fans or curtains. The device's spherical lens gives it a better look at its coverage area, allowing it to better detect any human intruders. And with temperature compensation, the device will operate properly even when the ambient temperature is close to the human body.
An adjustable pulse count for the WNX-40IX allows the user to configure its sensitivity settings as needed. The maximum battery life is 7 years, and it uses a CR123A for power. An LED status light displays the current status of the system. This version works with Interlogix/GE and Qolsys Systems.
