Essential Info

OPTEX's outdoor detection affords many advantages for your security. The LX-402 Outdoor PIR Motion Detector is not only easy to install, but provides greater protection against false alarms started by sunlight. This detector is well-suited for Outdoor activation, annunciation and automation functions. Covering a 40 x 50 foot net this detector sports special UV resistant lenses and casings for outdoor utility. The Detector also has an easy Pet Alley adjustment capability, selectable sensitivity and pulse counter, very strong Sunlight & RFI Immunity, integrated photocell, and a Form C relay output. Normal outdoor passive infrared detectors frequently produce false alarms begun by sunlight. But, OPTEX's LX-402 uses Double Conductive Shielding which can resist more than 50,000 lux of sunlight (for example, during sunrises and sunsets). This provides highly stable coverage, while letting the unit be used in a variety of applications and settings.

Use the included masking strips to create a specific detection pattern, if desired. In this way, the 40 X 50 Outdoor PIR w/Double Conductive Shield can be used as a pet-immune motion detector or can capture motion only in specific spots. Sensitivity can also be set at high, medium, or low. This motion detector has an adjustable day/night mode that you can set depending on the ambient brightness of the surrounding area. Set the sensor to function 24 hours a day, only during certain hours, or only after dark.

    I use this as a driveway alert, on a light post at the beginning. It works great, although this is my second one. The first stopped working for some reason after seven years so I had to replace it.
    MICHEL -- montreal, QC   9/30/2012
    Product does what it's supposed to do but causing way too many false alarms. This seems to be typical of outside motion detectors.
    STAN -- buffalo, NY   8/26/2010
    Works great. Used two of these to replace some cheap PIR sensors that were supposedly "outdoor," but would falsely trip hundreds of times per day due to varying shadows. This is a great solid unit, easy to use, and has many settings. Works flawlessly. Would definitely buy these again.
