- Page 2 Function It’s well known that LED lights have a totally different spectrum to natural light. Hytronik uses this principle and comes up with special photocell and sophisticated software algorithm to measure and differentiate natural light from LED light from behind the xture cover, so that this photocell can ignore internal LED light and only respond to the natural light outside.
- Page 3 By connecting the “SYNC” terminals in parallel (maximum 10pcs, see wiring diagram), no matter which sensor detects motion, all HCD418/DH 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.
