Will these audibly alert with other hard-wired smoke detectors if one of those activates, or do you NEED to replace every detector with nest?

Nest Protect does not communicate with non-Nest Protect alarms. If you have a large house, I would recommend replacing them as your current alarms die or gradually. I've done it this way and it doesn't seem like such a financial burden rather than doing it all at once.

Yes, the unit sounds an audible alarm. If connected to a system, it also causes all other detectors to sounds, the base unit to sound, and alerts the monitoring company (subscription required).

They give you many rooms to choose from (e.g., Office, Master bed room, kitchen, living room, etc.). I've had mine for many years, so they may have added extra options since I purchased these. You might want to call First Alert if there is something specific you need. I LOVE them and recommend them to everyone. If an alarm goes off, it's good to know where the fire or carbon monoxide is and not have to guess (like with typical alarms that just make noise, but don't talk).

You assign the smoke detector a certain code and then if it goes off, the main unit will send you a text and you will see by the code that it is your smoke alarm

I bought the First Alert OLCOMBOV SmartBridge Wireless Interconnected Smoke/Carbon Monoxide Combo Alarm with Voice and Location with these two and connected all three. I put the talking one in my bedroom and one of these in hall and the other in 2nd bedroom thinking if it went off at night I would want to hear the talking one. they work well together. how many you can add I'm not sure but it looks like adding to them is not a problem.

All of the wireless detectors that have been paired together will alarm in unison and will announce what alarm location the threat is detected. There is no switchable frequency as they all operate on the same wireless frequency (not Wi-Fi).

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.

I wish! I had 120 in an apartment building and couldn't even begin to tell you of the countless false alarms we've had since they were installed in 2010. I never found one to mix and match with these. If it is hooked into a relay check that too as sometimes that is the problem.

You have to follow the installation procedures exactly to make the detectors link. There is a sequence necessary to make them discoverable as the same linked network. Once properly linked, they will all sound together when a test or alarm is triggered.

any high quality, i.e. duracell or energizer alkaline battery, just remember to replace it before it starts to beep. When you wait for it to start beeping, you usually pull the battery and don't immediately replace it, which defeats the purpose of a smoke detector. I change mine with fall daylight savings time.

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. This is exactly what we did. We had several smoke detectors and one went bad.

If your BRK is battery only and there is no house voltage run to the smoke detector location then you will have to get an electrician to install the circuit. Otherwise purchase a Nest battery only model that does not require house voltage.

I believe they all sound off with a verbal alert as to the unit that has detected a problem. I don,t think you can switch the frequency.

Just Google your existing smoke detectors and see what is the recommended replace.

They have not. Nest only says they need to be cleaned out or they are faulty and will replace free of charge. The problem is- they are faulty. I've tried 8 different nests 6 of 8 have had false alarms. Iced lived in my home for 17 years, never a false alarm with the builder grade alarms. Just low battery beeps a few time when I didn't change the batteries regularly. I returned all of mine for a full refund.

These are designed to connect to each other not to other brands and types of alarms. We have other existing units which will be triggered their own by smoke but will not chain react with the kiddes. The units are bought of same brand and set up to trigger each other from a different part of house or close houses , garages or sheds...So a garage unit could alarm in your home to notify you if as soon as a fire was causing smoke and before your car burned up.
