Do I need to turn off (disconnect) the garage overhead door power before install it?

It is always a good idea to unplug the door opener when working on it for safety reasons.

No, it is not necessary from an electrical standpoint. The button runs on a low voltage system, hence you will not get shocked. However, you could inadvertantly activate your opener by touching the two wires together or pressing the button while tightening the scews. If this is a concern you could unplug the unit first. Hope this helps.

There is a setting in the setup that will get rid of the warning after the first time you power it up and the door is closed.

Correct. Will work without power. Has a manual switch as well. Great switch for the price.

Why would you want to? Switch off (open circuit an remove power) is the same as a power outage. Light would come on until battery dies.

Mine is direct wired into the panel box to it's own breaker and left on all the time. You need to have a qualified electrician do the install.

Sorry but, I just went ahead and connected the neutral since it was there, I don't know if it's required.

Bernie, Not sure I understand your question...Do you mean you want to disable the alert produced when power has been interrupted?Please explain your situation and I will try to answer.Thanks,steve

Yes there is a switch to turn it off,but I also unplug it just to be on the safe side.

Not on the door you leave through. I have similar device on doors to the back yard where it is not an issue. Besides, nothing is absolute. Personally, if I were a thief I try the garage door first. I now unplug mine when away on vacation, just in case.

No. It's a simple install that needs only a switch, and connection to 12V power and ground.

You can disconnect the power lead to them. See the wiring schematic that ships with it. I believe it will also disable the green also which indicates the switch is "on" which you may not want to do. If you stick one of the pictures that come with it over the light it isn't as bright. I'm not where the schematic is right now to actually look at it to be sure of the details.

You should definitely turn off the power before you hook this up. If this is hooked to your alarm panel its likely powered by the transformer in the alarm panel. What I did is called my alarm company, asked them to put my system in test mode and let them know that I was powering down the alarm panel. I turned off the breaker for the alarm panel, and then did the sensor swap....Powered the system back up and called the alarm company to put the system back into active. mode. Risky that you damage the new sensor if you try to hook it up with the power on...I don't recommend it.

Check connections behind it and connections on the overhead.. it's low voltage will not hurt bad if u touch the wires..I touched wires together behind the panel to see if panel needed replaced..sure enough when I touched wires together door would raise lower stop so replaced panel and it works fine..ten minute fix

If you have an Off/On switch just disconnect it and wire the control unit as described in the instructions in place of the switch making sure you have the wires (power in and power out and ground ) wired correctly.

you definitely have to turn off ac power. the 2nd clamp can go to the bare (earth ground) wire

It goes off when the circuit fails or you lose power. It has saved me twice. If you are concerned about a freezer door poping open, put a latch on the door. Does not have to be fancy, any hardware will do. I did that after my freezer door popped open and wasted the contents. Good luck. Chris

Simple answer is yea you can. Whether you or someone else install just let them know you don't want the remote start function. Even if they do it install it a switch can turn it on or off whenever you want it disabled. Hope this helps.
