With sufficient natural light, the
light does not switch on when
presence is detected.
With insufficient natural light,
the sensor switches on the light
automatically when presence is
detected.
After hold-time, the light dims to
stand-by level if the surrounding
natural light is below the
daylight threshold.
Light switches off automatically
after the stand-by period
elapses.
Manual Override
4
* Short Push (<1s): on/off function;
On
→
Off: the light turns off immediately and cannot be triggered ON by motion until the expiration of pre-set hold-time. After this
period, the sensor goes back to normal sensor mode.
Off
→
On: the light turns on and goes to sensor mode, no matter if ambient Lux level exceeds the daylight threshold or not.
* Long Push (>1s): adjust the hold-time brightness level between10% and 100%.
This sensor reserves the access of manual override function for end-user to switch on/off, or adjust the brightness by push-switch,
which makes the product more user-friendly and offers more options to fit some extra-ordinary demands:
Note: if end-user do not want this manual override function, just leave the “push” terminal unconnected to any wire.
With sufficient natural light,
the lights does not switch on
when presence detected.

Synchronisation Function

The lights dim to stand-by
level after hold-time, or turn
off completely if surrounding
natural light is sufficient.

By connecting the “SYNC” terminals in parallel (maximum 10pcs, see wiring diagram), no matter which sensor detects motion, all
HCD418/I in the group will turn on the lights (ambient natural light is below daylight threshold). The detection area is widely
enlarged in this way while other settings such as hold-time, stand-by period, stand-by dimming level and daylight threshold on each
individual unit stay the same.
The lights switch off
automatically after the
stand-by period.
