No More False Alarms

Are your rambunctious four-legged friends constantly setting off your alarm? It's time to invest in a WS4904P DSC Wireless Pet Immune PIR Motion Sensor, which distinguishes between human beings and pets weighing up to 60 pounds. No more embarrassing calls from the monitoring company, and no more late-night rude awakenings. There are a lot of pet-friendly sensors out there, but few are as reliable, as accurate or as long-lasting as this one, and Home Security Store is offering this leading technological innovation at an unbeatable price.

Accurate Detection

The WS4904P is compatible with most DSC alarm systems, and offers an array of cutting-edge features that set it light years above the competition. For example, it adapts to changing environmental conditions and works effortlessly even through the most frigid winters and the most blistering heat waves. And with DSC's patented Multi-Level Signal Processing (MLSP), you can ensure a more accurate detection of human IR (infrared) energy over a broad range of temperatures.

Wireless Reliability

This device uses 433 MHz of low power radio frequency (RF) technology to ensure the maximum possible battery life. In fact, the sensor can run for up to 9 years on a single long-life lithium battery, and with digital signal analysis, you won't need to worry about signal degradation caused by noise, distortion, amplification or signal clapping. You won't find a sensor that's better equipped to prevent false alarms and malfunctions.

Product Features

  • Reliable 433 MHz technology
  • Digital signal analysis for consistent detection throughout the coverage pattern
  • Exceptional catch performance at elevated temperatures
  • Patented Multi-Level Signal Processing (MLSP) for accurate detection of human IR energy over a broad range of temperatures
  • High-traffic shutdown
  • Temperature compensation
  • PCB antenna
  • 1 long-life lithium battery included; capable of up to 9 years of battery life
  • Sensitivity adjustment to configure the detector for "normal" (high sensitivity) or "hostile" (low sensitivity) environments
  • RoHS compliant
  • FCC/IC, UL/ULC listed for North America
  • CE compliant for Europe

In the 3 years I have had this installed, I have had 3 false alarms (while the system is armed) from my 8 pound Jack Russel Terrier. Like everyone else, I tried different settings unsuccessfully. I also had one of these sensors go off in a empty room with no pets or windows in its range of view. Since that one was under warranty, I sent it back for a replacement and I haven't had any additional problems in that room.

Wish it instantly transmitted once it detected motion.

I also have a small 9 lb cat. I have the sensor mounted eight feet from the floor. My couch is six feet from the wall. I have the jumper set to slow. I have followed all the installation instructions precisely which even mention "a cat on a couch" yet I throw a cat treat on my couch and the sensor always triggers when he jumps up to get it. My cat causes "swinger" events from this sensor nearly every day. Since there is no way to adjust the sensitivity this device is unacceptable.

This is tricky... However, YOU MUST READ the Manual! There are several details you must pay attention to. Make sure that battery is removed for 30 seconds, before putting in another. Let it settle for a few minutes before using the unit. Make sure that the unit is properly mounted as per the guidelines. Make sure that sensor side is towards the floor while LED side is towards the ceiling. Do not mount the other way around! It will not work! Make sure that it is vertical... Understand the meaning of 6 second delay. Understand how to set FAST and SLOW modes by changing the jumper setting on the PC Board. Then it works awesomely!

I am a DSC installer, we are facing difficulties when installing those motion detectors and hand them over to the customer, their response sucks, and we have to jump in front of the motion to trigger it if any.. If someone know a way to trigger this motion by simply walking in front of it, please tell me. It is embarrassing to us every time we install a system. I don't care to replace the battery every two years, if it will make the response of this PIR better.

I also have a 25lb dog who sets this detector off every time. I've followed all the instructions. The fast and slow jumper settings made no difference for me either.

Not pet friendly. I have changed response to slow from fast and still my 9lb cat sets off the motion detector. I have mounted detector 7.5 feet high on corner wall of family room. It is a wide open area with 10ft ceilings. Sensor does not look out to any windows.

This is a great wireless PIR sensor for the DSC wireless receivers and keypads with wireless receivers. It's very easy to setup and it's very reliable. The LED only lights when you're in test-mode to save on batteries. It will only transmit an event to the receiver once every three minutes to save on battery power (unless you're in test-mode). be sure to read the instructions to understand how this test-mode works.
