## Summary description

Infrared barrier No name AN900-B250 is a 3-beam perimeter detection device (model AN900-B250). It uses three infrared beams to detect interruptions across a protected zone and is intended for intrusion detection and perimeter protection. Suitable for installation at gates, fences or entryways where a compact multi-beam photoelectric sensor is needed.

## Long description

Infrared Barrier No name AN900-B250 is a three-beam photoelectric perimeter detector designed to monitor short-range zones such as gates, fence lines and entryways. The device detects interruptions of any of its three infrared beams and generates an alarm signal when a beam is broken. Its compact format and multi-beam arrangement provide reliable detection for locations where a small, discrete intrusion sensor is required.
Advantages
The three-beam arrangement reduces false alarms by requiring detection across multiple aligned beams, while the infrared transmit/receive pairing delivers fast response to crossings or attempts to pass through the protected plane. The compact housing is suitable for mounting on posts, gate pillars or existing fencing hardware. The unit is compatible with typical alarm control panels and can be integrated into perimeter security systems for enhanced zone monitoring.
Suitable for
 Perimeter protection along fences and walls
 Gate and driveway entry monitoring
 Small site or residential boundary detection
 Integration with alarm panels and access control systems
Key specifications
 Detection type: photoelectric infrared beam interruption
 Number of beams: 3
 Mounting: surface or post mounting for gates, pillars or fence posts
 Coverage: short-range perimeter zones (designed for gate/fence line use)
 Output: alarm signal compatible with common security control panels
 Environmental suitability: intended for outdoor perimeter use (weather protection depends on installation and housing placement)
How to use
Install the transmitter and receiver units facing each other across the zone to be protected, aligning the three infrared beams so they cross the intended entry path. Securely mount each unit to a stable support such as a fence post or gate pillar and adjust vertical and horizontal alignment until all beams are properly aimed and received. Connect the alarm output wiring to the control panel or alarm interface according to the system wiring diagram and verify operation with walk-test interruptions of each beam. Perform final tightening of mounts and weatherproof any exposed cable entries after alignment and functional testing.
Usage recommendations
Position the units to avoid direct sunlight into the receiver and minimize reflections from adjacent surfaces. Maintain clear line-of-sight between transmitter and receiver and periodically check alignment and lens cleanliness. For reliable long-term operation, combine the barrier with complementary detection methods and follow any local regulations for perimeter intrusion systems.
