Infrapunavalopuomi AN900-B250 3 säteellä, 250 m ulkokantama

Perimeter security gaps leave properties exposed to undetected intrusions, especially across wide driveways, fence lines, or industrial yards. The AN900-B250 infrared barrier closes that gap with a triple-beam active infrared detection system that reliably triggers an alarm when any beam is broken. Built for harsh outdoor environments, it combines long-range coverage, adjustable response timing, and robust weatherproofing to keep your boundary secure around the clock.

Who is it for

This infrared barrier is ideal for homeowners, business owners, and facility managers who need to protect large outdoor perimeters such as gates, walls, rooftops, parking lots, or agricultural land. It suits both residential estates and commercial or industrial sites where wired alarm systems are preferred for reliability and low maintenance.

Main features

• Three synchronized infrared beams reduce false alarms caused by small animals, leaves, or debris.
• Outdoor detection range up to 250 m (750 m indoors) for extensive perimeter coverage.
• Adjustable response time from 50 ms to 700 ms to match the specific security scenario.
• NC/NO relay output for easy integration with alarm panels, sirens, or access control systems.
• IP65-rated weatherproof housing with UV-resistant polycarbonate for long-term outdoor durability.
• Optical viewfinder and LED alignment indicators simplify precise installation and aiming.
• Tamper protection triggers an alarm if the unit is opened or removed.
• Operates on 12–24 V DC with low power consumption (max 140 mA for transmitter and receiver).
• Wall or pole mounting options for flexible placement.

Tips

For best results, mount the transmitter and receiver on stable surfaces at the same height and ensure a clear line of sight. Use the optical viewfinder to align the beams precisely, then fine-tune with the LED indicators. In areas with heavy fog or rain, consider reducing the response time to avoid false alarms. Connect the relay output to a wired alarm zone and test the system regularly to maintain reliable perimeter protection.
