CC status LEDs. For details, see DX2-CC2 Contact Closure Sensor LEDs (on
page 25).
High-speed ashing of CC1 LED indicates that the DX rmware upgrade is in
progress.

The four LEDs, from left to right, indicate the states of CC2,
CC3, CC4 and CC5 respectively.
• Boom row:•
The LED indicates the CC1 state.
DX-PIR Proximity Infrared Sensor
DX‑PIR contains one occupancy sensor (that is, presence detector), one tamper sensor and a pair of
terminals for connecng 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 moon of a person by sensing the temperature dierences between a person and the
surroundings.
