## Long description

The Barrier AN900-A100 2-Beam Infrared Sensor is a professional-grade security solution engineered for robust perimeter protection and reliable intrusion detection. By utilizing two synchronized infrared beams, this system establishes a secure, invisible detection zone that triggers an alert when both beams are interrupted simultaneously. Designed for high performance, the sensor ensures consistent operation and immunity to false alarms caused by small animals or environmental interference, making it a dependable choice for securing sensitive areas.
Advantages
This infrared barrier offers exceptional stability and precision in monitoring outdoor and indoor perimeters. The dual-beam technology significantly reduces the risk of false activations, ensuring that only genuine intrusion attempts are detected. Its durable construction is built to withstand various weather conditions, providing long-term reliability for security systems. The system is easy to integrate into existing alarm infrastructures, offering a seamless way to enhance the safety of a property without complex configuration.
Suitable for
Residential perimeter security
Commercial building access control
Industrial site monitoring
Protecting gates, windows, and doorways
This sensor may not be suitable for environments with extremely dense fog, heavy snowfall, or persistent thick vegetation that could permanently obstruct the infrared beams. It is also not intended for use as a primary life-safety device in fire or smoke detection systems.
Key specifications
Dual-beam infrared detection technology
High immunity to false alarms
Weather-resistant housing
Compatible with standard alarm control panels
To use the Barrier AN900-A100, mount the transmitter and receiver units directly opposite each other on stable surfaces or dedicated poles. Ensure the beams are perfectly aligned to maintain optimal signal strength. Once mounted, connect the device to your alarm control panel according to the wiring diagram provided in the installation manual. Perform a walk-test to verify that the system triggers correctly when the beams are interrupted.
What to consider before purchase
Ensure the mounting distance between the transmitter and receiver is within the manufacturer's recommended range
Verify compatibility with your existing alarm system voltage and output type
Check for potential obstacles in the line of sight between the two units
For optimal performance, regularly clean the optical lenses of the sensor to prevent dust or debris accumulation, and perform periodic testing of the alarm trigger to ensure the system remains fully operational.
