Wired passive infrared motion sensor for alarm systems. Uses passive infrared detection to sense moving heat sources in a three dimensional space and sends an alert to a compatible alarm host. Designed for reliable indoor coverage with low power consumption and minimal interference from common electronic devices. Key benefits Reliable detection: Dual rectangular infrared elements with low noise and sensitivity provide stable motion sensing across a wide area. Low power operation: Designed for low consumption and passive sensing, suitable for continuous use with minimal energy draw. Reduced false alarms: Strong immunity to electromagnetic interference helps prevent false triggers from mobile phones and other household electronics. Discreet installation: Compact, white ABS enclosure with a lowprofile appearance that blends into home interiors. Host integration: Wired output sends a signal to an alarm host. The host can trigger a decibel alarm and, if configured, notify users by text message or call. Main features Detection method: Low noise, sensitivity dual rectangular passive infrared Detection area: Approximate coverage 8 x 8 meters (26.2 x 26.2 ft); effective sensing angle about 110 degrees. Detection distance can vary with installation and is commonly within 2 to 12 meters. Installation height: Adjustable mounting from 1.1 to 3.1 meters Working voltage: 1116 VDC Alarm output: Normally closed, 28 VDC, 0.15 A Size: Approximate 90 x 66 x 52 mm (3.5 x 2.6 x 2.1 inch) Weight: Approximate 100 g Material and color: White ABS plastic Compatibility and installation This sensor is a wired device and requires connection to an alarm host or control panel with a compatible normally closed input. Mount on a wall at the recommended height range (1.1 to 3.1 m) for coverage. Adjust angle to cover windows, doors, corridors, bedrooms, or living areas. Wiring and host configuration determine whether the system can generate remote user notifications by text or call. Practical applications Window protection: Install near windows to detect intruders approaching or entering through window openings. Living room and bedroom monitoring: Provide broad coverage of main living areas while remaining discreet and unobtrusive. Entryways and hallways: Use to monitor corridors and entry points where early detection is important for alarm response.
