Key Differences Between the WXI and WXS Series

Although both series are built for dependable 180-degree detection, they differ in several significant ways:

1. Design Concept

WXS Series: Features bold, visible face covers and is available in multiple colours, enhancing the aesthetic of modern architectural settings.

2. Installation and Alignment

WXS Series Only: Includes an integrated back cover spirit level, helping installers achieve perfect alignment for optimal sensor performance. This feature is not present in the WXI models.

3. Mounting Options

Both Series: Support low mounting (0.8 m to 1.2 m), suitable for detecting crawling intruders or small animals.
WXS Series Only: Offers an additional high mount option at 2 meters, with adjustable internal settings for low or high mount configurations. This adds flexibility for varying installation scenarios.

4. Day/Night Mode

WXS Series Only: Features a day/night alarm mode, allowing alarm outputs only when ambient light levels are low (night mode). When this setting is disabled, the sensor can trigger alarms during both day and night.
