ABH-150L ALEAN Active Quad Infrared Beams 150m. The ALEAN ABH-150L is a high-performance active infrared beam detector designed for reliable perimeter protection in both residential and commercial security systems. Engineered with advanced quad-beam technology, this device delivers enhanced detection accuracy while significantly reducing false alarms, making it ideal for demanding outdoor environments. Featuring a detection range of up to 150 meters outdoors and up to 450 meters indoors, the ABH-150L provides long-distance coverage with exceptional stability. Its four synchronized infrared beams operate simultaneously, ensuring that only genuine intrusions trigger an alarm, while minimizing interference from small objects, weather conditions, or environmental noise. The unit incorporates selectable interruption response times (50ms, 100ms, 300ms, and 700ms), allowing installers to fine-tune sensitivity according to site-specific requirements. Additionally, it supports four configurable frequency channels, effectively preventing cross-interference when multiple beam systems are installed in close proximity. Designed for durability, the ABH-150L features an IP65-rated weatherproof housing, ensuring reliable operation in harsh conditions such as rain, fog, snow, and extreme temperatures ranging from -25°C to 55°C. Its adjustable optical alignment (horizontal ±90° and vertical ±10°) simplifies installation and guarantees precise positioning. For added convenience, the detector includes a digital LCD display for accurate signal strength indication, enabling fast and efficient alignment during setup. The device also offers NO/NC relay alarm outputs and tamper protection, ensuring secure integration into any alarm system. Overall, the ALEAN ABH-150L stands out as a robust and reliable solution for perimeter intrusion detection, combining long-range performance, intelligent filtering, and durable construction to meet the needs of modern security installations.
