Product Name: ABF Series Non-Rechargeable Wireless Infrared Beam Detector
Overview:
The ABF series 8500mAh non-rechargeable wireless integrated infrared beam detector is powered by a 3.6V lithium battery and equipped with multiple infrared beams (2, 3 or 4 depending on model), making it suitable for long-distance outdoor use. The product is designed for perimeter protection and height restriction of fences, providing reliable anti-theft alarm functions. It adopts 433MHz wireless communication technology, is easy to install, suitable for indoor and outdoor wall installation, has a waterproof rating of IP65, and can adapt to various complex environments.
Precautions:
The ABF series non-rechargeable wireless infrared beam detector is an active intrusion detection device that achieves perimeter protection and anti-theft alarm through the emission and reception of infrared beams. Its working principle is as follows:
Infrared beam emission:
The detector's transmitter is equipped with an infrared emission module that emits one or more (2, 3 or 4, depending on the model) precisely focused infrared beams. The transmitter is powered by A 3.6V 8500mAh non-rechargeable lithium battery, with A low emission current (170μA for dual light, 220μA for triple light, and 240μA for quadruple light), ensuring a battery life of up to 3 years. The beam frequency is adjustable (supporting four frequency options) and needs to be matched with the receiver to reduce interference.
Infrared beam transmission:
The infrared beam is transmitted in a straight line to the receiver, covering the specified alarm distance (50 meters, 80 meters, 100 meters, 120 meters or 150 meters depending on the model). In the absence of obstructions, the light beam travels stably along a straight path, making it suitable for outdoor open environments with a communication distance of up to 100 meters.
Beam Reception and signal processing:
The receiver is equipped with a photosensitive receiver and a signal processor inside, which receive the infrared beam emitted by the transmitter and convert it into an electrical signal. The receiver is also powered by A 3.6V 8500mAh lithium battery, with A low receiving current (180μA for dual light, 180μA for triple light, and 180μA for quadruple light). The receiver processes the signal through digital filtering technology to reduce the interference of environmental light or weather factors (such as rain and fog), ensuring the reliability of the detection.
Alarm trigger mechanism:
When the infrared beam is not blocked, the receiver continuously receives the beam and outputs a high-level signal, indicating a normal state.
When the infrared beam is completely blocked (such as when someone or an object passes through the beam path), the receiver cannot detect the beam and outputs a low-level signal, triggering an alarm. The alarm cycle is ≥25 seconds to ensure stability and minimize false alarms.
The alarm signal is transmitted to the alarm host or related equipment via 433MHz wireless communication, with a communication distance of up to 100 meters (in open environments).
Environmental Adaptation and Protection:
The equipment features an IP65 waterproof rating, operates within a temperature range of -25°C to 55°C, and has an ambient humidity of ≤95%RH (without condensation), making it suitable for complex indoor and outdoor environments. The transmitter and receiver support horizontal 360° (±180°) and vertical 180° (±90°) Angle correction to ensure precise beam alignment. The digital filtering and environmental adaptive functions further reduce the false alarm rate and adapt to various weather and lighting conditions.
Installation and Operation:
The transmitter and receiver are installed through the wall and feature a one-click quick locking design, making installation simple and convenient. The device does not require wiring and is powered by batteries. The transmitter and receiver need to be set to the same frequency to ensure stable communication. The alarm method of complete infrared beam blocking ensures that the alarm will only be triggered when there is a clear intrusion behavior, enhancing reliability.
The ABF series detectors provide efficient perimeter protection and height limit alarms through infrared beam occlusion detection, and are widely used in unmanned orchards, fish ponds, construction sites, border outposts, communication rooms and other places. Its low power consumption, wireless communication and high protection performance make it particularly suitable for outdoor scenarios that require long-term unattended operation.
Warning distance depends on the model: ABF3-50 covers 50 m, ABF2-80 covers 80 m, ABF4-100 covers 100 m, ABF3-120 covers 120 m, and ABF4-150 covers 150 m. The 433MHz wireless link reports alarms to the host up to 100 m in open, line-of-sight conditions, making the series well suited to long-range outdoor perimeter protection.
Each transmitter and receiver runs on a non-rechargeable 3.6 V 8500 mAh lithium battery with a service life of up to three years. The very low operating current — 170-240 uA emission and 180 uA reception depending on 2/3/4-beam configuration — means no wiring, no mains power, and no recharging. Simply replace the battery at end of life.
More beams reduce false alarms and resist small animals or debris triggering the alert. The ABF Series offers 2-beam (ABF2-80), 3-beam (ABF3-50, ABF3-120) and 4-beam (ABF4-100, ABF4-150) models. An alarm fires only when the infrared beam is completely blocked, so a single intruding person or object across the beam path triggers a reliable intrusion detection signal.
Yes. It carries an IP65 waterproof rating and operates from -25 °C with humidity up to 95%RH non-condensing, with digital filtering to limit weather-related false alarms from rain or fog. It is designed for wall-mounted perimeter and height-limit protection in unmanned orchards, fish ponds, construction sites, border posts and communication rooms.
Both units mount on a wall with a one-click quick-locking design and require no wiring since they are battery powered. Set the transmitter and receiver to the same beam frequency (four options) to ensure stable 433MHz communication. Horizontal 360 (±180) and vertical 180 (±90) angle correction lets you align the beam precisely for an unobstructed path.
