I picked up a pair of Heath/Zenith Dual Brite Motion sensing
porch lights. Mod# sl-4151-br1-b. The kind you can set to stay
on dim all night but turn on bright when motion is detected.
I'm going to mount them either side of the 2 car garage door.
I want to wire them so that if either unit detects motion they
both turn on.
The directions call this a "dual master system" but don't tell
you how to do it.
The lights have a black, white and red wire.
One light, use black/white.
Two lights, use black/white and the red is the hot to second light.
Two motion sensing lights, use white/black and the red is the hot to
the second(slave) motion sensing light tied to both its black and red.
I figure i will need a third conductor between the two lights
(got a roll of 14/3 laying around). but how do you wire it up
so either will turn the other on?
p.s. if it matters, the red is actually a pigtail off a red and a black
going to the motion sensor.
