Do you guys ever run a 3 wire to flood lights...black wire constant feed to motion and red wire to flood heads controlled by single pole switch?

What you want to do is have the constant feeding the sensor , you use the 3 wire to get a neutral to the switch, feed the Red from the 3wire with the Red wire on the sensor, black wire from the three wire goes to the flood heads.

Right?

Done it countless times. Use a SP for On/Off and a 3-way for Manual/Automatic.


Why wouldn't you just switch the sensor?
That powers the photocell/motion sensor. Try turning the light on when you want to.

I only use rab motion sensors, turn the light switch off on off on and the light will stay on until the next dawn. Guess most other motion sensors dont have this. Have done the three way on photocells.

The Heath Zenith sensors do as well. I use Rab and HZ.

Most of 'em do. But I still wire them this way because no matter how well you explain the 'turn-off-then-back-on to turn on the light' to the customer, they'll forget before their check clears their bank. "Honey, do you remember how to control this light? I remember the electrician saying something about the switch, but it makes no sense to turn it off so I can turn it on......"

2 switches make it stupid-proof.

Do you want the light On or Off? OK, turn this switch up for On, down for Off. That's easy. Now, do you want the lights to come on only when dark/motion is detected, or do you want them to come on no matter what? OK, that's what this switch does.

I'm with crazyboy on this one. Someone draw a schematic, I can't wrap my small brain around it.

SP feeds the 3way, and the 3way acts as a spdt? Where one half lights the lamps and the other the motion? And you need a jumper across the motion and lamps in the fixture?

Argh:mad:

Sp feeds the common on the 3way, one "traveler" feeds the motion photo assembly which is also tied to the lamps, the other traveler feeds the lamps after the motion photo assembly. Is that pretty much it?

Thats why they come with a sticker for the cover plate with instructions on it :laughing:

I use to do my floods with 3 wires all the time until I realized you can bypass the motion by flipping the switch. Now I just run a 2 wire cable
