IRM-23 Series PIR Motion Sensor
IRM-23 Series Motion Sensor is equipped with both PIR and 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 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.
