Gate Detector ABO20 Protect entrances and detect motion reliably with the ABO20 IR alarm detector. Designed for small supermarkets, convenience stores, garages, and gate entry points, this wired transmitter and receiver pair offers stable performance in challenging environments and simple installation for fast deployment. Key benefits Reliable detection: Singlebeam IR pair detects motion and beam interruptions with precise response, reducing missed events. Weatheradaptive sensitivity: Builtin AGC circuit automatically increases sensitivity in poor weather, while a watt transmitter and 90 percent sensitivity margin support stable operation in harsh conditions. Easy integration: Wired output works with automatic doors, alarm systems, and gate openers to add a layer of intrusion detection or obstruction sensing. Low power operation: Designed for continuous use with modest current draw, minimizing impact on existing power systems. Durable for indoor and outdoor use: Resists rain and dust exposure for perimeter and entryway applications. Technical specifications Model: ABO20 Type: IR alarm detector, singlebeam transmitter and receiver pair Working voltage: 12 V Alarm current: 50 mA Quiet current: 5 mA Detection angle: 10 degrees Detection distance: 20 m Emission distance: 1520 m (49.2165.62 ft) Emission frequency: 1520 MHz Action distance: 12 mm / 0.47 inch Working temperature: 1070 C Communication: wired Alarm output: wired Installation: wallmounted Application scope: garage, gate, window, balcony, access control Installation overview Recommended mounting height: greater than 20 cm. Minimum spacing between units: at least 1 meter. Position IR devices vertically and align them on the same horizontal plane. Install the receiver first, then the transmitter. During alignment in a straight line the receiver indicator will turn off when properly aligned. Secure, wire, and test the pair to complete setup. Use scenarios Store entrance: Detect customers or potential shoplifting activity at a convenience store or small supermarket doorway and trigger an alarm or counting system. Gate and driveway: Integrate with a gate opener to detect vehicle or pedestrian approach and prevent gate strikes or unauthorized entry. Perimeter and window protection: Monitor garage doors, balconies, or groundlevel windows to detect motion or beam interruption before an intruder gains access.
