# VESTA-TXI-RDAM-X5

## OPTEX TXI PIR curtain detector for outdoor use with microwave, anti-masking and VESTA F1 wireless transmitter

<figure><img src="/files/vhPBTdOoJpvph7mEZowJ" alt=""><figcaption></figcaption></figure>

The TXI-R offers overhead curtain-type volumetric detection, providing stable and consistent detection thanks to OPTEX’s advanced Triple AND logic (patent pending). Designed to create a narrow detection field along the façade of a building, it enables the detection of potential intruders before they reach the premises. The TXI-R is ideal for perimeter protection in detached houses, balconies, warehouses, office buildings and retail premises, as well as for any application where it is necessary to protect the boundaries of a property.

The TXI features a unique configuration with Quad + Dual volumetric detection and is powered by OPTEX’s SMDA digital logic, designed to ignore the movement of animals within the detection zone, reducing the risk of false alarms in environments where pets or wildlife may be present, without compromising intruder detection performance.

With a compact, palm-sized design, the TXI-R can be installed at a height of up to 4 m and offers a detection range of 12 m, which is adjustable to prevent over-reach, and an optional zero-angle setting, allowing coverage to be tailored to the requirements of each installation whilst maintaining a discreet setup.

## Functions Overview

#### Pet Tolerance

This product is equipped with a triple AND logic to reduce false alarms. The triple AND function activates the alarm only when infrared changes are simultaneously detected in three separate detection zones. This mechanism significantly reduces false detections caused by small pets.

#### Accelerometer tamper

This product is equipped with an accelerometer that accurately detects movement and vibration. An accelerometer measures changes in velocity (acceleration) when the device is moved, tilted, or subjected to impact. This enables the system to detect tampering, abnormal motion, or unauthorised handling, enhancing overall security performance.

#### Anti-masking&#x20;

This product is equipped with an anti-masking function, which detects attempts to block or obscure the sensorìs field of view. Anti-masking refers to the ability to detect intentional interference with the sensor, such as covering the lens or placing objects in front of the sensor. This feature helps prevent tampering and ensures the security system remains effective.
