Pattern

Operation

1

Flash in response to occupancy

Flashes green in response to a motion event. Noticeable as person moves under a sensor node and settles after 3 seconds if no motion is generated and flash again if it detects motion again. This pattern is responsive to occupancy events and happens all the time in normal automatic operation mode

2

Flashes regularly at 2 Hz

This operation is visible when there is any scene activated on a sensor node whether it is through a wall switch, an app, the Portal or even BACnet. The nodes will resume to automatic operation of flashing in response to a motion event when the scene expires or when manually set to On/Auto

3

Flashes regularly at 2 Hz

In addition to above, this behavior is evident when the lights are configured to absence detection mode. Once absence has been detected for time equivalent to dwell and lowlight time combined it will turn off with “off scene” activated. In order to resume normal operations a manual “On/Auto” is required.

4

Retaining previous LED state

This would mean that the LED will remain in its previous state whether it was lit or off at the time when an external dim command is sent. As an example, if a dim command is sent exactly at the same time as when the LED was flashing it would retain its last status.

Operation

1

Solid red combined with Green LED always lit*

If a sensor node remain solid red at all time, then it means that it could mean that its PIR has been disabled. This would happen on any or all such nodes within a zone which haven’t seen any break in occupancy for the past 24 hours. This feature is built to address the following cases;

1. A space can be very busy and occupied e.g. nurses’ station in an emergency ward. This acts as further safety towards not turning the lights off on busy spaces by disabling the PIR. To revert back to normal operation a power cycle or reset to factory settings is required.

1. Troubleshooting a space with false triggers due to environment or related interferences. In cases where a singular luminaire out of the zone or multiple luminaire would keep picking up motion while the other nodes don’t detect any presence in a period of time. The sensor node would keep count of all such event and would eventually have it’s PIR disabled and its node solid red to help investigate the false triggers in that space

2

Combined sequence when “Automated Self-Test Sequence” is running

1. The dome LED will flash red once to indicate that it has power supplied

1. Next, after about 10s, the dome LED will flash red again after the power cycle and dimming performance test has been completed

1. Lastly, after about 24s, and simultaneously, the dome LED will flash red again once and the green LED will flash steadily 20 times after the colour temperature test has been completed (for DT8 drivers only)

Note: The same LED sequence will run regardless if it is a DT6 or DT8 driver.

3

Combined sequence when Automated Self-test sequence is disabled

Simultaneously, the dome LED red will flash red again once and the green LED will flash steadily 20 times
