SRX-2000A Detector Manual.pdf

The SRX-2000A is a professional passive infrared and microwave detector with anti-mask features, including a hard spherical white lens, unique detector protection, and diffractive reflection mirror for creep zones. It has VLSI-based electronics with movement speed spectrum analysis, bi-directional temperature compensation, and microwave sensitivity adjustment. The detector provides analysis of environmental conditions, allowing focus on intruders and elimination of false alarms. It has a combined technology of PIR and microwave, with alarm signal relay activation only when signals from both sensors are present. The effective detection range is where the patterns of PIR and MW intersect, and the GAIN potentiometer adjustment changes the MW signal intensity. The detector has LED indicators for MW detections, PIR detections, and alarm, and rapid blinking of all three LEDs indicates anti-mask. Installation instructions include choosing a location, avoiding direct sunlight and areas with rapid temperature changes, and connecting wires to the terminal block. The detector has dip switch settings for PIR, LED, and anti-mask, and sensitivity calibration for MW and PIR potentiometers. Test procedures include a one-minute warm-up time, walk test, and observation of the red LED lighting when motion is detected. The detector has interchangeable hard type spherical lenses with various coverage patterns, including wide angle, long range, and curtain.
