can you replace this alarm by pluging in a new one or do yo have to rewire

I had to rewire the new "plug" to the old wires...3 wire nuts and the wires are color-coded...so not a big deal...+ mount new alarm base plate...takes about 15 min. per alarm, with system check after each installation, DGF, Colorado.

Hi Dorothy, Sorry for the delayed response.....I have spent the last two days 'upgrading' my Operating System from XP Pro to Windows 7 and my computer was off line.The alarms do not come with a plug, they are 'hard wired' into a receptacle box. Does that answer your question? -Roy

In my case I changed brands in one home and had to rewire. But throat her home this was just a simple remove attach the wire to the new unit. If you have a first alert then you just connect the new unit, if not your results can vary.

We had to contact our Alarm Company to have them verify that this Keypad would be a comparable replacement. It did but there are other things to consider. We had to remove the battery from the main box before we started the replacement and the last wire you hook up is the green wire. It is the Hot wire. Good luck

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!

It should be an issue to replace one model for another as long as the voltage is the same (US 120V). You may have to install the connector that comes with the new alarm if it has a different connector. Otherwise they are both ionic sensing and very similar in functionality.

J. Hur,This will not be a problem. I have 3 different models connected to my hard wired/ plus battery system. A total of 6. Some with different sensitivity than others. Since they are all made by First Alert / BRK. I haven't had any problem with them for over 21 years now. Plus they all come with a wiring harmess pigtail, should you damage your old one . I have noticed some of the new replacment detectors have replaced the 9-volt battery with two AA . To be honest, I think it's better . I hope this helps you.Ronnie

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.

This is not direct replacement. But you can use it if you know wiring correctly.

Mine needed new batteries after a year. The batteries are available at Walmart for almost $6 EACH. Because it requires THREE batteries, it's cheaper to replace the alarm than purchase batteries.

Yes, but to do so you must replace one of your existing units with/or add one Kidde 1279-9999/RF-SM-AC Hardwire Smoke Alarm with Battery Backup, Interconnectable, to your existing system (assuming that your presently installed devices are a different brand other than Kidde). The Kidde 1279-9999/RF-SM-AC is capable of communicating with the Kidde 0919-9999/RF-SM-DC Battery-Operated devices and will receive/activate alarms from/to other wired units. If you already have a Kidde 1279-9999/RF-SM-AC installed, then you are in great shape, just add the Kidde 0919-9999/RF-SM-DC units as needed.

just pull out of old one and used by little power. Very easy. you can figure out if you get the new one.

There is a test button on each, that you should be able to change.. They still need batteries changed even though they wired.. see if a nice neighbor will change the batteries. most of the smoke detectors have a 10 year life.. so you should be okay on that. they may just need new 9 volts

the 2 old units I replaced were Lifesaver Model 1255 - I think most units are standardized to communicate over the 3rd wire so all alarms connected together sound when any one goes off. If you don't require that feature, I think any standard 2 wire unit can replace any other. See this link to help in deciding if you want photo or ion (or the combo unit I bought) https://www.nfpa.org/safety-information/for-consumers/fire-and-safety-equipment/smoke-alarms/ionization-vs-photoelectric

Yes. If you are trying to add a new zone to the alarm and ADT tech will have to program it in. If replacing one you will be fine.

You just wire it to the terminals in the control panel that lead to your other alarm. There is enough current to drive all alarms

I bought this alarm as the equivalent replacement for old alarms in my home. I was able to use both the existing mounting bracket and the hard wire connector. Took me only a matter of minutes to replace all the alarms in the house.

The alarm is designed to be plugged into your wall like any other appliance. If you have a bit of electrical knowledge you could hard wire it. I simply plugged mine in since I had an open receptacle. Hope this helps.

NO I agree with Fred buy the complete unit. In my case mine was old enough that they were not the same. Just write the color coded wire order before you remove them. Very easy to change.
