The VX-402 Series has unique technology which makes it absolutely the most stable outdoor sensor which utilizes Passive Infrared Technology. Designed to provide Reliable Performance, Ease of Installation and Multiple Applications for the Dealer and End User. Advanced PIR technology takes a giant leap into the future of outdoor detection. Our patented design allows this sensor to adapt to many different applications and offer reliable detection and unique deterrent capability. Click Here to See Detection Patterns The Highest Reliability Available in Outdoor Detection The patent pending "MDP" Technology eliminates the chance of false alarm caused by moving objects or small animals within the detection area. The VX-402 includes the first Layered Detection Pattern which provides logic for discrimination of objects in the detection area. The upper zone stays parallel to the ground at all times and the lower zone is adjustable from 6.7ft. (2.0m) to 40ft. (12m). Only when both upper and lower zones are activated will the VX-402 generate an alarm. Limited Detection Range Function The detection range of the VX-402 can be limited to avoid detecting unwanted objects. By eliminating detection range, false alarms due to unwanted movement (i.e. cars, persons or animals outside the detection area) can be reduced. Size Judging Function The VX-402 is designed to discriminate between large and small objects. By utilizing this ability, false alarms due to small animals can be virtually eliminated. Bright Light Disturbance Immunity with Double Conductive Shielding The VX-402 is equipped with Patented Double Conductive Shielding Technology. A special conductive filter covers the element window allowing infrared energy to pass through while blocking and grounding out light and RFI sources. High Durable Housing & Lens Weather Proof Structure (IP54) Easy Installation Installation of the VX-402 has been simplified by the addition of a conduit access in the bottom of the unit. You can conveniently install the VX-402 anywhere since it can be wired either through a conduit access in the bottom of the unit or through a wiring access on the back of the unit. In addition, rubberized grommets increase the resistance of the sensor to the attack of natural elements. Wiring Convenience Wiring can enter the sensor from the top or bottom, making installation quick and easy. Built-In Conduit Entry A conduit can be installed directly into the bottom of the unit by removing the knockout on the cover. Area Masking Plate Unwanted detection area(s) can be easily eliminated by attaching supplied masking plates. Area Angle Adjustment The detection area can be adjusted 45° left or right from the center to allow for custom applications for the sensor. Extensive Application By connecting to additional detectors such as PIRs, Active IR Beams, or Magnetic Contacts, the VX-402 can provide additional features without the use of any special control panel. Self-contained functions can offer not only higher reliability but also the ability to be utilized in various applications. Detection Area Extension Function Wiring two VX-402 sensors together and selecting the "OR" Mode will allow the detection pattern to be effectively doubled. Directional Detection Function The VX-402 can also be used in conjunction with another sensor to create even greater stability. By selecting the "AND" Mode and programming which sensor should be activated first (DIP Switch Programming), the VX-402 can sense direction and will activate only if motion is in a specific direction. Sequentially Confirmed Alarm Containment With this option selected, an alarm will only be generated if two detectors activate sequentially and separately. This function dramatically increased the reliability of the system. It is no longer necessary to reduce sensitivity or parallel sensors together. The logic is all internally controlled. Various Applications The VX-402 is equipped to provide Directional Access Control features. Applications for this technology include opening an automatic gate when approached from one direction, counting cars or people going one direction through an area and not counting those going the other way.
