DX2-PIR Proximity Infrared Sensor
DX2‑PIR contains one occupancy sensor (that is, presence detector), one tamper sensor and a pair of
terminals for connecng a contact closure (CC) sensor. The sensor package provides:
• Two RJ45 connectors - for connecon to sensor port and chaining•
• One infrared sensor for moon detecon•
• One contact closure sensor•
• One tamper sensor•
• Two DIP switches•
• One LED•
▶
Occupancy sensor:
The occupancy sensor is located on the top of the DX2‑PIR. It uses the passive infrared technology to
detect the moon of a person by sensing the temperature dierences between a person and the
surroundings.
▶
Tamper sensor:
The tamper sensor is located on the back of the DX2‑PIR. This sensor is used to detect whether the
DX2‑PIR is moved away from its original posion. In the normal state, the DX2‑PIR is rmly axed to an
object so this sensor, which is a buon on the back of DX2‑PIR, is pressed down. If someone takes the
DX2‑PIR away, the buon springs up so the sensor is in the alarmed state.
