HI All. I have 4 led floodlights around my house for security - all timeguard 30W LED with PIR. I currently have a timeguard 30W PIR on one corner of the back of my house by the back door and i'm about to add a second identical unit to the other corner by our patio so both lights illuminate the entire back of the house, converging in the middle. These particular lights have L1 outputs for setting up additional lights as slaves when the unit is triggered and activated - very straightforward but not what i'm after. I would like to ask is if this is possible: Can they be set up so that if either unit detects motion (one or the other), both lights come on? For example if the PIR unit by the back door detects motion and illuminates (but the patio one hasn't detected motion) can they be wired in such a way that the patio one will illuminate anyhow without its PIR as yet being triggered. Similarly id like the same to be true for the when the patio PIR is triggered - it also switches on the one by the back door. My spark has wired all existing lights for standalone operation and isn't sure if this is possible.
