### **1. General Description**

The **VESTA-350** is a dual passive infrared (PIR) motion detector specifically designed for **top-mounted installation on windows and doors**, offering a **narrow curtain detection pattern**. It is ideal for early intrusion detection with high accuracy and minimal false alarms.

{% hint style="success" %}
The VESTA-351 is **designed to work in conjunction with the** [**VESTA-148**](https://vesta-guide.gitbook.io/vesta-guide/vesta-148) **sensor**, creating a robust perimeter protection solution. The HE-100X series includes both **hardwired and battery-operated models**, with available **dual-tech antimasking** versions integrating microwave technology.

### **5. Installation Recommendations**

* Mount at the **top center** of the door/window frame
* Install **adjacent to the VESTA-148** where dual-layer detection is required
* Configure pulse count and logic depending on site-specific sensitivity requirements
* Avoid proximity to moving objects (e.g., curtains), reflective surfaces, or air vents

***

### **6. Precautions**

* Ensure secure mounting to avoid tamper or vibration-related false alarms
* Clean Fresnel lenses regularly to ensure optimal detection performance
* Dual-tech models should not face devices that emit microwave or heat signals
