Dsc ws4904p Wireless Pet-immune Pir Motion Sensor

Product Description

The DSC ws4904p is a wireless passive infrared (PIR) motion sensor designed for residential and light commercial security systems. It uses digital signal processing to detect human infrared energy while filtering out common false alarm sources such as air vents, radio interference, and insects. The pet-immunity feature ignores animals weighing up to 60 pounds, making it a practical choice for homes with pets. Operating on 433 MHz RF technology with a low-power PCB antenna, the sensor delivers consistent detection across a wide temperature range without signal degradation from amplification or noise. Licensed security technicians and qualified installers are the primary end users.

The ws4904p is suited for corner or wall-mount installation in residential spaces where pet traffic would otherwise trigger false alarms. Its hybrid installation classification means it can be deployed by professional installers or by knowledgeable end users following manufacturer guidelines. The sensor adapts to changing environmental conditions by adjusting internal detection parameters automatically, maintaining reliable catch performance across varying temperature ranges. Where wireless zoning is preferred over hardwired runs, this detector integrates into compatible DSC wireless receiver systems.

Key Features

• Pet immunity rated for animals up to 60 pounds, reducing nuisance alarms in occupied residences
• Digital signal processing analyzes IR data in software, eliminating degradation from analog amplification or noise
• 433 MHz low-power RF technology extends battery life without sacrificing range or sensitivity
• PCB antenna design provides consistent RF coverage and sensitivity across the detection zone
• Adaptive detection parameters automatically adjust to environmental temperature changes
• Corner and wall mount options allow flexible placement to maximize coverage area

Compatibility

Designed as an OEM-style wireless PIR sensor for use with compatible DSC wireless receiver systems that support 433 MHz RF devices.

Installation Notes

Installation should be performed by a licensed alarm technician or a qualified installer familiar with low-voltage security system wiring and local codes. Power down or disarm the security panel before enrolling or replacing wireless sensors. Mount the sensor at the manufacturer-recommended height for the coverage pattern, using corner or wall placement as the layout requires. Do not install near heat sources, HVAC vents, or windows with direct sunlight exposure, as these can affect PIR detection reliability.
