DMP 1127W-W Wireless PIR Motion Sensor Wall Mount Pet Immunity

The DMP 1127W-W is a professional-grade wireless passive infrared motion detector designed for wall-mount installation in commercial and residential security applications. Engineered by DMP, a recognized name in professional intrusion detection, this sensor wirelessly communicates motion events to compatible DMP security systems, eliminating the need for dedicated wiring runs and simplifying both new installations and retrofits in finished or hard-to-wire spaces. A key design consideration of the 1127W-W is its built-in pet immunity, which allows the detector to distinguish between the movement of small household animals and a genuine human intruder. This capability significantly reduces the incidence of false alarms in environments where pets are present, making it well suited for monitored residential properties, small offices, and light commercial spaces where animals may roam freely. For professional installers, the wireless form factor and pet-immune detection combine to reduce callback rates, shorten installation time, and deliver a reliable, low-nuisance alarm experience for the end user.

Key features & benefits

• Wireless Operation — Transmits motion detection signals wirelessly to the host DMP security system, removing the constraints of hardwired sensor placement and enabling clean, efficient installations in retrofit or finished-construction environments.
• Passive Infrared Detection — Utilizes PIR technology to sense the thermal signature of moving individuals within its coverage zone, providing reliable human motion detection without requiring active illumination or emitted signals.
• Pet Immunity — Incorporates pet-immune sensing logic that allows smaller animals to move through the detection zone without triggering an alarm, helping to maintain system credibility and reduce unwanted alerts in pet-friendly environments.
• Wall-Mount Form Factor — Designed for standard wall-mount deployment, allowing installers to position the detector at an optimal height and angle to achieve broad area coverage while keeping the device unobtrusive within the protected space.
• DMP Ecosystem Integration — As a genuine DMP product, the 1127W-W is purpose-built to integrate within the DMP security platform, ensuring consistent enrollment, supervision, and event reporting behavior expected by professional installers and central station operators.
• False Alarm Reduction — The combination of PIR detection and pet immunity directly supports lower false dispatch rates, which is a critical performance metric for monitored security installations serving residential and small commercial clients.
