Working Principle

The JNS Series detector operates by emitting infrared beams between a transmitter and receiver. When an intruder interrupts the specified number of beams (two, three or four) simultaneously, the device triggers an alarm via the relay contact output. The anti-sunlight feature minimizes false alarms caused by direct sunlight or strong reflections, while the anti-theft design ensures the device cannot be silently removed — tampering opens the anti-disassembly contact and signals the alarm panel.

Product Introduction

The JNS Series Wired Infrared Detector is an advanced security device designed to protect perimeters with anti-sunlight and anti-theft capabilities. Available in eight models with different beam configurations and detection ranges, it integrates seamlessly into wired security systems — alarm panels, access-control controllers, video-surveillance NVRs with sensor inputs, and PLC-based site monitoring.
