VX-402 is suitable for almost all outdoor applications because it combines two PIRs, creating extra high immunity against false alarms caused by small animals, cars, and other outdoor disturbances. Easy wiring and a 90° wide angle detection pattern with 180° aiming are significant advantages that VX-402 brings to outdoor security. VX-402 also includes temperature compensation circuitry, high RFI and Sunlight immunity, Form C relay, adjustable photocell, sequential logic circuit, and many other features for quality outdoor performance.
Optex's 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, thereby eleminating flase alarms caused by small animals and unwanted objects and movement (i.e. cars, persons or animals outside 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.
The VX-402 is equipped with Bright Light Disturbance Immunity 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.
Area Angle Adjustment/Area Masking - The VX Series' detection area can be adjusted 45° left or right from the center to allow for custom applications for the sensor. Similarly, unwanted detection area(s) can be easily eliminated by attaching supplied masking plates. The Detection Area Extension Function allows the detection pattern to be effectively doubled by wiring the two VX-402 sensors together and selecting the "OR" Mode. By connecting to additional detectors such as PIRs, Active IR Beams, or Magnetic Contacts, the VX-402 offers extensive applications and features without the use of any special control panel. The VX-402 is equipped to provide Directional Access Control features, including 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.
An innovative Directional Detection Function allows the VX-402 to 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 activates only if motion is in a specific direction. A Sequentially Confirmed Alarm Containment option generates an alarm only if two detectors activate sequentially and separately.
