Adi Pro WST-741 Rf Pir Pet Immune Motion Sensor 319 Mhz

Product Description

The ADI PRO WIRELESS SENSORS PIR WST-741 is a wireless passive infrared motion sensor designed for use in residential and commercial security systems. 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.

The 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.

Key Features

• Wireless RF transmission at 319 MHz for compatibility with supported security panels and receivers
• Pet-immune PIR detection reduces false triggers from small animals
• No hardwire run required, simplifying installation in retrofit or finished-space scenarios
• Single-unit packaging for direct replacement or new zone deployment

Compatibility

Designed as an OEM-style wireless PIR sensor for use with security panels and receivers that support 319 MHz RF sensor input. Confirm panel compatibility before installation.

Installation Notes

Installation should be performed by a licensed alarm or low-voltage technician familiar with RF security sensor placement and zone programming. 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.
