Learn Mode DS-924 Motion Detector
A Passive Infrared (PIR) Sensor is designed to detect movement in the interior of a structure. The PIR Sensor detects infrared temperature changes, such as the temperature emitted from the human body. The coverage area of a PIR sensor is divided into several zones and the PIR senses infrared temperature change in these zones. Any sudden thermal movement across these zones will cause the PIR to send an alarm signal to the Control Panel. The Learn Mode DS-924 is UL Listed for residential use only.
