DX-PIR Proximity Infrared Sensor
DX‑PIR contains one occupancy sensor (that is, presence detector), one tamper sensor and a pair of
terminals for connecng a contact closure (CC) sensor.
▶ Occupancy sensor:
The occupancy sensor is located on the top of the DX‑PIR. It uses the passive infrared technology to
detect the moon of a person by sensing the temperature dierences between a person and the
surroundings.
