Thee red is for 240 volt , the black and white are for 120 volt . Most likely when you remove the old emergency light it will be white wire to white wire and black wire to black wire. if you see a red wore comeing out of the wall or ceiling just use the red wire in the emergency light and place a wire nut over the black wire in the new emergency light.

Don't know how to work with 2 wires. This switch took three wires: blue for load, black for hot line, and white for neutral line. You need to have three wires to make it work.

Red connects to +12VDC, black connects to ground. You don't need yellow, don't connect it to anything.

If you truly have only 3 wires total regardless of color than you can not use this switch. The light you are trying to turn on is using a switch leg where you connect black to white with a standard 2 pole light switch. There needs to be 6 wires in the box for this switch to work. No disrespect to the other people who answered but I don't think they read the problem statement correctly.

I had to go look. There are two terminal blocks. One with 3 and one with 4. My system is wired thus: 3 Term- unused, green,yellow through resistor., 4 term - Black, red, unused, unused. I just diagramed the old one before removing it and placed the wires back on the same terminals. I don't have any other colored wires with this system. My guess is the 4 term block are + and - and the 3 term block are the outfeeds to the monitor/alarm panel. Hope that helps.

I have copy of instructions. I can send send them? Trick is the Yellow wire is the control wire. If you want it on all the time (which is the way I hooked it up). Black wire to negative, red and yellow to positive.

If there's red and black then it's red. If it's white and black then it's white. If there both the same color then one should have letters or numbers or line on it and that would be pistive. Sorry been a while since I hooked them up can't remember what colors the wires were.

Unit has four wires. Red and Black load wires are clearly labeled, as are black L1 and red L2. Connection diagram is included in the instructions booklet.

If you're referring to the pictures 3 red wires. it's one power hookup to fuse. = power into the switch, out of the switch, and then back into the module. Then turn the switch on and plug in your phone to listen. Then turn switch off and listen to the radio

Three wires rgb indicates red green blue. V indicates ground or negative. Use a dmx512. Use youtube for I structions

Yes, I only used three wires but one of the wires must be a C wire for the RedLink to work.

The Instructions are a little confusing, I had to just go by what each wire does: I used Conventional Diagram! I also Double checked connections On the internet utilizing how my old one was connected & tagged the wires with the corresponding letters shown on the wiring diagram? I don't know if I have confused you more O actually helped you? Good Luck! =O)

I bought two units and they both look just like the picture... one red wire and one black wire. Sorry that I'm no help.

Wire a 3-way switch. Or just disconnect the 2 wires and twist them together.

Thanks, for your question. The ones I purchased from Amazon I had installed by my Son so I could not honestly tell you why one would have 3 wires or two. Now, with that being said my home was built in 1995 so it's not that really old. I cam assuming that depending on how old or new is your home may make a difference. When I see three wire I think positive, negative and ground. A suggestion, you maybe able to connect the negative to the ground making two wires instead of three. Your neighbor if they have the same home chances are they may have change there also so they be of some help also. Good Luck.. Thanks, for your question.

There aren't 3 power wires. The provided switch connects to 2 of the red wires. That leaves one power wire to run to a 12v source. There is also a black ground wire. Please refer to the diagram that came with the instructions. Given that you actually have this question, I too would suggest using an install technician...

Oops, forgot to answer this part. The red switch is for high/low speed setting.
