Optex has launched the TXI Series, a range of high-mount outdoor curtain detectors designed for residential and commercial perimeter protection. Built to create an invisible curtain barrier along a building façade, the TXI Series is designed to address the challenge of balancing reliable human detection and nuisance alarm reduction in external security.
At the heart of the TXI is Optex’s Triple AND Logic, which uses three independent sensing areas to create three detection zones, with an alarm only triggered when all three zones detect simultaneously. Working in combination with Super Multidimensional Analysis (SMDA) digital processing, which analyses multiple characteristics of detected movement to help filter environmental noise and support more stable performance as conditions change, these technologies help maintain reliable human detection while reducing nuisance alarms.
For installers, the TXI Series has been designed to support flexible set-up across different sites. The detectors offer a selectable mounting height from 2.2m to 4m and a 12m x 2.4m curtain coverage area. An optional look-down zone addresses a common vulnerability in high-mount installations and can be enabled or disabled depending on requirements. Installation is supported by included brackets to enable secure fitting and concealed wiring, with an optional TXI-BKT ceiling/wall mount bracket available for angle and gradient adjustment.
