Operating at 319 MHz, it transmits detection signals to a compatible wireless receiver or security panel without the need for hardwired runs. The WST-741 features pet-immune detection logic, allowing it to distinguish between small animals and human-sized movement, reducing false alarms in homes or facilities with pets. It is typically installed by security system technicians and alarm integrators as part of a broader intrusion detection layout.\u003c\/p\u003e\u003cp\u003eThe WST-741 is suited for interior spaces where wireless installation is preferred or where running wire is not practical. Its pet-immune capability makes it a practical choice for residential retrofits, light commercial applications, and monitored security installations where false alarm reduction is a priority. The sensor ships as a single unit and is intended for wall or corner mounting at standard detection heights.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWireless RF transmission at 319 MHz for compatibility with supported security panels and receivers\u003c\/li\u003e\n\u003cli\u003ePet-immune PIR detection reduces false triggers from small animals\u003c\/li\u003e\n\u003cli\u003eNo hardwire run required, simplifying installation in retrofit or finished-space scenarios\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging for direct replacement or new zone deployment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wireless PIR sensor for use with security panels and receivers that support 319 MHz RF sensor input.

Power down or disarm the security system before pairing or replacing sensors. Mount at the manufacturer-recommended height and angle to achieve the intended detection pattern. Avoid placement near heat sources, HVAC vents, or windows that may cause thermal interference with PIR detection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Frequency\u003c\/strong\u003e: 319 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Type\u003c\/strong\u003e: Passive Infrared (PIR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePet Immune\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ADI PRO WIRELESS SENSORS PIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: WST-741\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ECOLINK","offers":[{"title":"Default Title","offer_id":51689005941042,"sku":"WST-741","price":101.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/763f1361abf8e879a280d49196f0d2ec_5d5f4b25-b0e3-4df4-bfb7-263c70d5d8d4.jpg?v=1788253673","url":"https:\/\/voomisupply.com\/products\/adi-pro-wst-741-rf-pir-pet-immune-motion-sensor-319-mhz","provider":"Voomi Supply","version":"1.0","type":"link"}
