PIR motion detector JS-20 is designed for property protection. It uses multiple signal analyzing methods. Thereby it achieves excellent sensitivity and high immunity against false alarms. Detection analyses can be increased with adjustable jumper (in case the product is mounted in problematic locations). For high connectivity, the product is equipped with a free pair of terminals. The detector distinguishes itself with excellent RF immunity and other false signals. It can be mounted on a flat wall or in a corner.
