DSC Wireless PIR Motion Detector WS4904PW — Pet-Immune up to 27 kg, Wireless

DSC Wireless PIR Motion Detector WS4904PW is a battery-powered passive infrared detector engineered to detect human movement while reducing false alarms from pets. The detector features pet-immune sensitivity for animals up to 27 kg and communicates wirelessly with compatible alarm control panels, enabling flexible placement in homes, apartments and small business premises. Compact housing and a discreet appearance allow installation on walls or in corners to monitor entryways, corridors and living spaces without visible wiring.

Advantages

The WS4904PW provides motion detection using passive infrared technology with adjustable pet immunity, which reduces unnecessary alarms triggered by animals. Wireless connectivity simplifies installation and relocation, removing the need for running cables. Low-power design and battery operation extend maintenance intervals, and the detector's detection pattern and sensitivity are optimized for reliable identification of human movement within typical interior environments.

Suitable for

• Home entryways, living rooms and hallways
• Apartments and rental properties where wiring is restricted
• Small offices and retail areas requiring discreet motion monitoring
• Households with pets up to 27 kg where false alarms must be minimized

How to use

Install the detector at the recommended indoor mounting height and position it to cover primary approach routes such as doors and corridors. Follow the compatible alarm panel's enrollment procedure to add the detector to the system, typically by putting the panel into learn mode and activating the detector's wireless transmission. After enrollment, test the detection zone by walking through the area while the system is in test mode and adjust the detector angle if necessary to achieve optimal coverage. Replace batteries according to the control panel's battery status reports or the detector's maintenance schedule.

Usage recommendations

Place the detector so that pets cannot pass directly in front of the sensor at close range; position mounting at the recommended height and avoid pointing the sensor toward heating vents, large windows with direct sunlight, or air-conditioning units to reduce environmental triggers. Regularly test the detector after installation and during seasonal changes to confirm consistent performance.
