IRM-23 Series PIR/Microwave Motion Sensor
IRM-23 Series Motion Sensor is equipped with both PIR and Microwave motion detection technology. The combination of dual detection
methods greatly improves the Motion Sensor’s detection accuracy and reduces false alarm rate, by using the PIR as initial detection, and
microwave as confirmation before actually transmitting the activation signal.
The Motion Sensor has multiple models with different battery, tamper switch and Pet Immunity combination. Identify the function of your model
on hand with following table before proceeding to read rest of this manual.
The PIR is designed to give a typical detection range of 12 meters when mounted at 2 meters above ground.
The Pet-Immune models of IRM-23 series PIR sensor further support pet immunity feature and will not detect pets of up to 27 kg within 7 meter
range to minimize false alarm situation.
