TXI FAQ's
Battery life varies depending on model, mounting position, detection frequency and environmental conditions. Detailed battery life data for each model under defined test conditions is available in the product instruction manual.
Yes. The compact housing has been specifically designed with residential aesthetics in mind, a direct response to installer feedback that existing high-mount detectors are bulky and visually intrusive. The TXI is appropriate for both residential and commercial applications.
The TXI is OPTEX's high-mount outdoor curtain detector family, developed specifically in response to installer feedback.
Outdoor curtain detection presents a well-known engineering challenge. The sensitivity needed to reliably detect intruders is the same sensitivity that triggers false alarms from pets, small animals and environmental movement.
The TXI uses OPTEX's patent-pending Triple AND detection logic to achieve genuine pet tolerance “volumetrically” and reliable detection performance simultaneously.
The TXI family covers both wired and battery-operated installations, with and without dual-technology and anti-masking. All models share the same compact housing and installation approach, making the family straightforward to specify across different site requirements.
Traditional detectors trigger an alarm when a single sensor, typically PIR, registers a detection event. Dual-technology detectors require two sensors to agree before triggering, which reduces false alarms but can also reduce detection reliability.
Triple AND logic requires three independent detection conditions to be satisfied simultaneously before triggering. This allows the TXI to apply much stricter criteria to each detection event, achieving pet tolerance without compromising on capture performance.
If your current product is working well for you, the TXI may still be worth evaluating, particularly if you've experienced false alarm callbacks, pet tolerance issues or customer complaints about aesthetics. Those are the specific problems TXI was built to solve. We'd suggest requesting a demonstration or evaluation unit and judging it on your own sites.
Full technical documentation, including installation guides, detection zone diagrams, and datasheets are available to download from the product page. For application support or specification advice, contact your OPTEX Account Manager or regional distributor.
The TXI is designed for high-mount applications, typically installed at height to create a curtain detection zone across an entrance, gateway or perimeter line. Detailed mounting height recommendations, detection zone diagrams and installation guidance are included in the product documentation.
Pet tolerance in conventional detectors is typically achieved by reducing overall sensitivity which inevitably increases the risk of missed detections. The TXI approaches this differently. Triple AND logic means that a small animal moving through the detection zone will not satisfy all three required conditions, and therefore will not trigger an alarm, even at normal sensitivity settings. Detection performance for a human intruder is not sacrificed to achieve this.
