Yes you can. I have a system with 9 units. I have replaced several of the smoke alarms with smoke/carbon combination units. You can even reuse the connectors to save having to shut off the breaker and rewire.

Hi yes they are compatible with any number of units installed Yes place one near the garage such as a laundry room .You could also use a wall plug in unit also. Any combustible appliance heater, water heater, gas dryer in the house should have co2 protection Where I live herein Texas a co2 alarm is require next to every bedroom especially if the furnace unit is in the garage and feeds all the rooms through the house Hope this Helps.James Walsh

In our home we have a group of 6 smoke alarms, 2 of them being carbon monoxide detectors. They connect up to the wiring all the same, any way the ones I have replaced do, the smoke alarm/carbon monoxide detectors just preform more function.

Mine was installed near the ceiling and it worked fine to detect CO from an old stove's pilot light that malfunctioned and turned itself off. My apartment was slowly filling with gas that I only faintly smelled when entering. I believe I had the First Alert brand, but I'm sure they all work the same.

We have 2 (our house by code will need 9 total alarms but this issue has us paused on ordering more). Both had multiple false alarms within the first 30 days. We returned each (separately) and were sent new units. Neither has false alarmed and it's been almost a year since the first one (we got them right when they came out).

Nick, I really don't know. The landlord installed these ones to replace exactly what you have. Sinerely, has been an excellent choice since he does not want to be called in the middle of the night when the other alarms failed or run out of batteries making that bothersome beep beep we all have heard at 3 am, lol. I believe they are a thousand times worth the money invested and as a prime you may qualify for an extr discount on your homeowners insurance.

Make sure you bought the one for ng and not propane. I sure wouldn't burn it if your alarm keeps sounding.

That depends on the regulations in your area. Maybe ask your local building inspector. My experience was that the connector for the Kidde smoke detector that was already there did not work well with this unit. There were false alarms. It worked well after the correct connector was wired in, but it does not trigger the other Kidde detectors in the house.

The code could be solved if the alarm is due to dirty system. Misfires could damage the CAT a good garage can tell you but be aware that you have to pay for diagnostics. Trying and not deleting the alarm will put you back one bottle in monies.

You may need a battery-operated only smoke alarm, like the USI CD-9775 9-Volt Battery Operated Combination Ionization Smoke and Carbon Monoxide Alarm, which you can find on Amazon by typing in B002EVORNY into the search box. Amazon offers other battery-operated smoke / CO alarms by other manufacturers as well. Good luck.

The SA521CN is designed to operate as hard wired with other wired smoke alarms,and also connect to wireless "One Link" First Alert alarms. If hard wired you get power from the 110 volt connection. It also has two AA batteries which work when the power is off. There are other wireless models of "One Link" that look similar, use two AA batteries, and wireless connect among themselves and the SA521CN. I alrady had a hard wired system with First Alert connections. I purchased only one SA521CN to replace an existing hard wired only alarm, hard wired it, and also purchased some "One Link" alarms that operate only on two AA bateries. By having ONE SA521CN hard wired, if any alarm goes off--wireless or hard wired only, then ALL hard wired AND wireless alarms go off. Responding directly to the question, I assume this can be used strictly as wireless without a short battery life, but there are other models specifically operating on two AA only. I don't know if the battery life would be shorter on theSA521CN or not, but it will work..

Carolyn, I would think you could, I have mine pretty far a part so really can't answer your question. The sensor goes off quickly but takes 15-20 seconds to reset before the alarm goes off again. I also have a driveway alarm from Harbor Freight that is cheaper and they respond quickly and you can add another sensor.Sorry about the answer. I see what another posted. I've haven't had any issues with my alarms and really like them.

The cheap alarms only have one slot I think just for the shock sensor. In order to use the proximity sensor you would have to use the slot and forget about shock sensor. I'm using a viper so there is 2 slots.

The unit has a battery in case you lose electric power, but they are also connected to your house's electric wiring so the battery doesn't need to be replaced so often. In addition, when one smoke alarm goes off, all the smoke alarms in the house go off. This is important as I have a smoke alarm in the basement that I might not hear from some of the bedrooms if they all didn't go off together.

Ms. Kittay,I suspect you are trying to buy the smoke alarms from the same vendor I did. First of all, they do not come with an adapter. Secondly, I bought a package of 6 from the vendor to get a cheaper price. However, three of them started beeping (acting they were faulty) right from the start. My guess was that they were not "new" and might have been refurbished, although I was under the impression I was purchasing new products. So, I would instead try going to your local hardware store for these items. That way, you can return them there a lot easier (and cheaper) if they do not work out.I hope this helps you.Regards Ms. Kittay,I suspect you are trying to buy the smoke alarms from the same vendor I did.

I answered this several weeks ago, and I just checked the site and for some reason Amazon didn't post it; their bad! All of my smoke alarms were hard wired as per code. But if the 9v back up battery in one died, all of the alarms went off; I was up all night one night. Anyway, my old ones were not Kidde, but the Kidde replacements fit perfectly.Go to: www.kidde.com and find their Customer Support 800 #. They were very helpful when I called them. Good luck, and I am sorry my first answer was not posted; I have no idea what happened. navydoc

Thanks everyone for you comments. I have a carbon monoxide detector right out from my stove. We have also installed a fan over top of the unit. I guess it can't burn the fumes fast enough like gordyh was talking. If it gets worse will have a teck check it out. Again I would like to thank you all. Didn't think I would get a reply.

fire always brings Carbon monoxide. So if there is fire this will always go off. Can it replace a smoke detector > no just like smoke detectors can not detect CO.

Smoke Alarm side is photoelectric only. To have the ionization detection, you must purchase an additional alarm. Keep in mind that there is a maximum number of alarms that can be connected together.
