JS-7920 Alternative grey lens for JA-1x2P and JA-1x2Px

JS-7920 is an alternative grey lens intended for PIR motion detectors in the JA-1x2P and JA-1x2Px series. The lens is designed to modify the front optics and appearance of the detector, providing improved resistance against strong or direct white light that can adversely affect sensor performance.

This grey replacement is useful where a darker aesthetic is required or where ambient/incident white lighting could impact detection reliability. The lens is a mechanical/optical replacement and does not alter the detector's electrical characteristics or sensing algorithms.

Key points and installation notes:

• Compatibility: Models JA-1x2P and JA-1x2Px only.
• Improved resistance to intense white light sources that may cause false triggers or reduced sensitivity.
• Grey finish for better visual matching in darker interiors or facades.
• Before replacing the lens, verify the detector model and disconnect power to the device.

Do not modify detector electronics; replace only the lens element. If in doubt about fitment, check the detector model label or documentation before purchase.
