When replacing the Sentrol 240-COe with this new 250-CO, do I need to turn off power to the wires? If so, where do I turn the power off?

You don't need to cut power if you are careful with the wires. First ensure that your alarm is on test if it is monitored- it will go into trouble or alarm when disconnected. You can disconnect the wires and just cover them with tape while changing it. If you want to power down the alarm, just disconnect the battery inside the control panel and unplug the power transformer. Make sure you have the manual with instructions on resetting the clock if needed after powering up.

Yes. You should remove power. Follow Abbot F. answer for the steps. Some people answering are saying that "if you are careful" or the power is low voltage and won't hurt you. This isn't the main reason for removing the power. It is in your best interest to protect the new device installing, and also the panel you are connecting it to by removing the power before installing.

No. Just put your alarm system in test so you don't cycle your alarm monitoring company.

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.

The voltage is low, but be careful not to touch wires to each other so that no damage occurs. Cap them or tape them as you remove them. I don't think you can easily turn off power. Also, call your alarm company before you do this to not cause an alert.

Power down your alarm system by disconnecting the battery backup and unplug the transformer from its outlet.

First make sure your alarm company is notified to put your system on test. The following assumes use of standard phone wire (r-w-b-g):1. Unscrew (disconnect) the red wire & tape it (that's the power wire);2. Unscrew the white wire (ground);3. Unscrew the red & green wires (these are the alarms wires);4. If there's a resistor soldered to the red or green wire, leave it, you'll need to keep it in the circuit when you install the new unit.Good luck!

You need to disconnect the old battery from the leads and connect the new item using the old wiring. Please let me know if there is anything else we can assist you with.

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.

Com= common, NC= Normally closed: Check that the wires to the Com and NC go to you alarm panel. What happens is the NC is the same voltage as the Common terminal, if the alarm on the 250 goes off the Normally Closed term goes open and the voltage floats up to the + voltage setting off the sensor in your alarm panel. The Com wire should go to the C terminal next to the NC terminal on the new 250.

Easy if you are replacing the old ones, 2 wires and a ground wire. If this is a new install, as opposed to a replacement, you will probably need the services of an electrician. We love ours.

The power source's plugs needs to be cut and you insert the wires. Your best bet is to check youtube for videos on how to wire the whole thing up. There's a few great ones on there that break it down for you.

Hi Eddie. Unfortunately, You will need to turn it back on yourself after a power outage. Have a great day!Vermin

You have to use new one. I had to take panel off wall and fish wires all over again.

There is a little covered box on the side with wires inside. Just remove the cover and insert your wires, connect and recover. In my application I used armoured cable and a connectore for the hole. The unit I purchased was identical to the one it replaced.

You definitely have to wire this into your 240v circuit. No plug on this unit. Hope this helps.

Yes it is very simple and pretty basic.Make sure you write down the way the wires were so you don't forget.Loosen the screws holding down the wires, remove screws from the inside back of the Replace with new unit and connect the wires.

Corey, I hard wired mine. I remember reading somewhere they Do Not have a memory. So it will default back to original pattern when power is lost or disconnected. I just leave mine on original setting back and forth pattern.

If wired the way the instructions say, there is no way to disable. For the first trip out i unplugged the main positive wire. That can get old fast so, I installed an additional single master switch that gives/cuts power to the switch panel under my console. Still sucks but it's worth it

Greg, I have one of these on the front & I don't care a lick for it! Buy a bigger unit if you can! As far as wiring, I just made up a 2 strand wire harness & ran it along the inside edge of my deep v right down to the battery. I then split it & put a connecter for each post. It works like a charm! I'm no Guru when it comes to this kind of stuff either and I made it work. cbmgh@comcast.net if I cabn be of further assistance to you. CB

To optimize the power it should be direct wired.There are connections that are foresale to do that,If you have a weak signal tune to a station which has no interfereance.

It needs to be wired in. I just replaced it for a old one already there so it was just changing a couple of wires.

I looked it up, but could not see where this one was a match? Does not mean it won't work. My suggestion is to turn off the power and remove the old element and take it to your local appliance store and they should be able to find you a good match. Most of the differences are how the element power wires attach to the element. Those have to be a match or it could short out inside the unit walls and then it goes down hill from there!
