The dual-curtain outdoor perimeter PIR detector is designed to offer professional and reliable protection for windows, balconies, outdoor corridors, and fences. The dual-curtain PIR generates two narrow, independent beams, capable of highly precise detection of crossings of the protected area while avoiding unwanted interference. With an adjustable range of up to 12 meters per side , the sensor guarantees targeted protection suitable for any perimeter. The detection technology is supported by temperature compensation , anti-disturbance filtering, and motion analysis logic, minimizing false alarms due to weather changes, sun, wind, or small animals moving close to the ground. The integrated buzzer and status LED make testing, calibration, and verification of correct operation quick and easy. The device integrates advanced functions such as active anti-masking , which detects intentional cover attempts, and tamper protection , which signals the opening or removal of the sensor. Screw terminals and a convenient cable gland ensure a quick and tidy installation, while dip switches allow you to easily configure distance, LED behavior, alarm logic, and operating settings. Compatible with 10–24 V DC power and equipped with NO/NC outputs, the sensor is fully compatible with our zone alarm systems and most wired burglar alarm control panels on the market, offering immediate integration without adapters. Thanks to IP55 protection, this detector is resistant to rain, dust, and harsh outdoor conditions, ensuring continuous security all year round. Reliable, accurate, and highly configurable, it is the ideal solution for those who want professional and stable perimeter protection over time.
