ABE-250 ALEAN Active Triple Infrared Beams 250m. The ALEAN ABE-250 is a high-performance active infrared beam detector designed for reliable perimeter protection in both residential and commercial security systems. Engineered for long-range detection, it offers an outdoor coverage of up to 250 meters and an extended indoor range of up to 750 meters, making it ideal for securing large areas such as warehouses, industrial facilities, parking lots, and private properties. This model utilizes a triple-beam detection system, ensuring that an alarm is triggered only when all three infrared beams are simultaneously interrupted. This significantly reduces false alarms caused by small animals, weather disturbances, or debris. Additionally, the device incorporates advanced DSP processing and intelligent signal filtering, allowing stable operation even under challenging environmental conditions such as fog, rain, snow, and direct sunlight. The ABE-250 features four selectable frequency channels, enabling multiple beam pairs to operate in close proximity without interference. Installation and alignment are simplified through an integrated LCD or LED signal strength indicator, providing precise and efficient setup. The adjustable interruption time (ranging from 50 to 700 ms) allows installers to fine-tune sensitivity according to site requirements. Built with durability in mind, the detector has an IP65-rated weatherproof housing, ensuring protection against dust and water ingress. It operates within a wide temperature range from -25°C to 55°C and supports flexible power input (12–24V AC/DC). Additional features include tamper protection, relay alarm outputs (NO/NC), and adjustable optical alignment (±90° horizontally and ±10° vertically). Overall, the ALEAN ABE-250 delivers a robust, precise, and dependable solution for perimeter intrusion detection, combining long-range performance with advanced environmental resilience and installation flexibility. Features Selectable frequency 4 channels : Stacking, Straight line, Square or other various applications are allowed. Professional waterproof design with rubber seal around, anti-rain, snow, dew, mist, frost etc, IP65 ingress protection. Triple beam: interval of 3 beams is 20cm, improves the ability of anti-false alarms. Intelligent temperature control system, pre-set heater terminals. Environment adaptive function, according to external environment changes, timely adjust to adapt the state, reduce the false alarms rate. AGC circuit, the detector will automatically increase sensitivity when faced harsh environment. Horizontal ±90° / vertical ±10° optical angle can be easy to adjust. LED display signal grade for easy alignment. Adopt digital DIP technology,frequency,sensitivity,indicator and operation power can be adjusted through DIP switches.
