DSC WS4904P Wireless Pet Immune PIR Motion Sensor


  • No More False Alarms

    Pet Immune Motion detectors are perfect solutions for avoiding false alarms from four-legged friends that trigger your alarm system while you're away at work. Most of them are very good and will get the job done, but if you're looking for an extremely reliable, amazingly accurate and long-lasting sensor that you'll never have to worry about, then you want the DSC Wireless Pet Immune PIR (passive infrared) Motion Sensor.

    Compatible with most DSC Wireless Alarm Systems, it is among the most technologically advanced detectors available.

    Accurate Detection

    This motion sensor is immune from pets weighing up to 60 lbs. (27.3 kg). It adapts to changing environmental conditions by adjusting critical detection parameters, meaning it will perform at a high level through cold winters and blazing hot summers. With DSC's patented Multi-Level Signal Processing (MLSP), this alarm accessory provides a more accurate detection of human IR (Infrared) energy over a broad range of temperatures.

    Wireless Reliability

    433 MHz technology features the latest low power RF (Radio Frequency) technology to extend battery life. With a long-life lithium battery, the sensor is capable of up to 9 years of functionality. With digital signal analysis, digital information is accurately understood and is not subject to signal degradation caused by amplification, noise, distortion or signal clapping. For as long as you need, the DSC Wireless Pet Immune PIR Motion Sensor achieves superior detection and false alarm prevention, consistently.
