How to wire it from the old 240 to the new 250? is the red +12 to go to the +? the black ground to the -? the blue common to the C and which one there are 2, and the brown with transistor to NC also which one?

These are a little more confusing than the original units. The red and black still go to the + and - terminals (power). The remaining two wires are the output from the device which actually trips the alarm panel. The reason for the extra terminals is to maintain supervision of the device which puts the alarm zone into trouble when the sensor reaches the end of its life. You connect the wires to the NO and C and do not use the NC terminal (these are the three terminals on the other side of the detector). Next you put a short wire jumper between the C terminal where the alarm wire is and the NO terminal next to the power connection. Finally you will have to splice a short piece of wire to one end of the resistor and connect the wire to the NO terminal with the alarm wire and the other end of the resistor to the C terminal by the power connection. If everything is correct the alarm zone should ready ready and not in trouble. After placing your account on test, press and hold the test button for about 10 seconds. You will hear it beep a few times and then you will hear a click. At this point it should set off the alarm. Good luck!

The diagram for the wiring of the switch came with the new switch. Perhaps you can E-mail the manufacturer. As I recall I simply attached the new switch and its wires exactly where the old one had been with the original wires corresponding to the same relative positions in the new switch. Gee, as I re-read my answer I see room for mis-interpretation and a lack of a concise answer. I hope I have not made your situation worse.

Tom. Hook it to 12V positive along with the red wire with the fuse. The blue one can be used for a remote switch if need be. Doug

Go to this website, there is a discussion concerning the pinout and wiring: http://www.electro-tech-online.com/general-electronics-chat/122625-help-wiring-up-iec320-c14-socket.html

The red terminal is POSITIVE and the black one is NEGATIVE. I do not understand F1 and F2, as it may be specific to your schematic or circuit.

hi, im not sure what the yellow wire ism mine only have two wires blue and brown

for 220 use yellow/green for ground. the other 2 wires are hot. for 110 use yellow/green for ground. and use one wire hot and the other neutral.

Hi Dale just join the two red wires together and run them to positive and the black wires to negative leaving the fine black wire not connected good luck Chris A.

Just wire the new switch the same way the old one is. Match switch with the old one colors could have changed. Put wire off the old switch into the same position on new switch. Do one wire at a time.

Just go to radio shack. It's about $24.99 and they have them in stock. Takes 20 min to swap out.

You most likely need a switch with only black, white, & green. The red wire is hot though. With about half of the switches out there, you can wire nut the red & black to the black running to your panel. Not with the one you just got though.

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

If you will provide the brand and model (manufacturer), I will try my best to help you. I need to look at the schematic for that particular model. They are all different as far as wire colors. Thanks, Mike

I AM NOT AN ELECTRICIAN... My 240 is wired with 2 hot wires (one white one black) plus ground connecting to 2, 30amp fuzes. one hot wire to each fuze and the ground to the common ground in the fuzebox. #10 wire is required according to Aprilair. I STRONGLY suggest you get an electrician to do the wiring. THIS IS A LOT OF POWER. I watched my electrician do the wiring. In addition the Best thing to do is call AprilAir (800) 334-6011 directly.

The ones I used only had a blue and brown wire and the brown is positive and blue negative. The unit will also work on 12 VAC since there is a circuit inside to rectify and filter the power to 12 VDC. So, I suspect that this new Green/Yellow wire is for ground. I had several of these circuits fail because I was using in in a 12VDC system with a charging circuit that would take the voltage up to 14.5 VDC. You can allow for this if you add a 5 ohm/5 watt resistor in series with either the blue or brown wire.

The brown wire is the positive ,+, terminal which corresponds to the red wire. The blue wire is negative, -, which corresponds to the black wire. They should be labeled on the power supply. Even if you reversed them you won't harm the led's. They just won't light up.

Main Power supply in to switch. #1 Black Power To Black on switch. Green to ground . White switch to white motor. White main power to White Motor. If unit doe's not turn in proper way, Just switch the 2 whites at motor around. If you have any other problems, contact me veia e mail at vietvetbob1@hotmail.com. Or call cell at 973-903-5071 . Leave message with your phone number and I will try my best to assist you. GL, Bob
