Optex LX-402CL Cover and Lens for LX-402 Pir Detector

Product Description

The OPTEX LX-402CL is a replacement cover and lens assembly designed for the LX-402 passive infrared (PIR) detector. This component restores the optical and physical integrity of the sensor housing when the original cover or lens has been damaged, cracked, or lost. Licensed security technicians and low-voltage alarm installers typically handle this replacement as part of routine detector service or post-installation repair. The lens directly affects detection pattern accuracy, so using the correct OEM-matched replacement is essential for maintaining intended PIR coverage.

This cover and lens assembly is suited for residential and light commercial security installations where the LX-402 PIR detector is deployed. It is a single-unit replacement component sold individually. Applications include retrofit service calls and warranty repair scenarios where the detector body remains functional but the housing or lens requires replacement.

• OEM-matched replacement cover and lens for the LX-402 PIR detector
• Restores original detection pattern geometry by replacing a damaged or degraded lens

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with applicable local codes. Power down or disarm the associated security zone before disassembling the detector housing to avoid false triggers or system faults. Handle the lens surface carefully to avoid scratches or contamination that could degrade PIR detection performance. Confirm the cover is fully seated and latched before restoring system power.
