If I own two Onelink smoke detectors that don't talk - they just beep, can I add this unit to the system? Will it link to my existing units?

Yes. Onelinks link. As stated in one of the bullets: "Interconnects with other First Alert ONELINK enabled alarms to create a wireless safety network". Bear in mind that they do not link very far. IE, link them next to each other and then try a mounting location prior to drilling the holes in the wall. Items within the walls like wiring and ductwork block the wireless signal so a slight move may make a lot of difference.

You can have Onelink detectors that beep on the same mesh network as detectors that talk. I found it 'dumbs down' the whole system. I had a detector report a low battery which sends the signal around the network. Of course, this happened in the middle of the night and the beeping detectors didn't handle it well. My best guess is that they kept repeating the signal and they are only capable of signalling fire. I started running around to each detector pulling the battery tray and they wouldn't stop until I pulled the battery on the last beeping detector. The beeping detectors have found a new home in a cupboard without batteries. You can have Onelink detectors that beep on the same mesh network as detectors that talk.

I contacted my home security company to get a list of sensors that are compatible with my existing security system. This one was one of those in the list. I would suggest you to do the same.

No. An No-one has wirelessly interconnected detectors that use both technologies individually in separate detectors. First Alert OneLink uses photo-electric technology, and has no ionization detectors. The best you can do with wireless technology at this time is to put one each of the Kidde and First Alert detectors in each room.

Let me start by commenting on the date on the device, since it has come up in other posts. I ordered my smoke alarms in May and the device was stamped end of March which seemed quite reasonable. Yep, replacement time is 10 years and if I do it exactly on the 10 year mark I'll be amazed with myself. As per your question Edwin I hooked up my alarms to the house power and they did the low battery beep until I pulled the plastic tab out of the side of the detector which made the battery connect inside the unit itself. I used the battery that came with the unit and didn't need to ever open the battery compartment. When I do replace the battery if it continues to beep I would check the battery connection and also make sure that my batteries were not dead. I expect to replace all the smoke alarm batteries the first of the year, which is what I used to do, and didn't bother this year because I knew I had to replace the detectors. Best of luck with your smoke detector.

I doubt it also since the 3120B uses a physical wire to link with other alarms and there is wires on the SCO501CN. Maybe there is another device that connects wired and wireless units?

I've had these for years. If one alarm senses smoke they all go off but will report the name of the alarm location, such as "Kitchen". To silence all alarms I believe you must silence the one in that location. This makes sense as you'd want to check that location. The other alarms will silence after a few seconds. I'm not sure if hitting the silence button on a different alarm will silence them all or just that remote location as the only times they've gone off I've just run to the one that is triggering the alarm. I think this has happened only in our kitchen and we're usually right there cooking when that has happened. I've had these for years.

It looks like it does come with the wiring via the online manual. The correct pinouts are there too. http://www.firstalertstore.com/store/images/pdf/SA521CN-3ST-First_Alert_Onelink_Wireless_Hardwired_Smoke_Alarm.pdf I had the same question and the previous "worked for me" answer didn't really help.

Is there a special way to configure the unit to do this or is it easy to do? All I want is local control of devices and my doors to chime when they are opened.Thanks again for all the help.Joe

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 think you'd need to buy one for each location. I have a second driveway system from a different manufacturer, and it chimes three times when tripped, as opposed to twice, as this unit does. This way, I can tell which location is alerting.

Adding Kidde alarm units to an established circuit has never been easier than with the Kidde RF-SM-AC. This hardwired wireless interconnectable smoke alarm with battery backup can expand your current coverage by simply replacing an interconnected alarm and adding the Kidde RF-SM-AC. Once this unit has become part of your circuit, you can add as many Kidde wireless smoke alarms as are necessary to expand your realm of protection. No wiring is required to install this device, as you can simply mount it on any wall or ceiling to start expanding your Kidde alarm circuit. If the alarm sounds to alert you of a possible fire hazard, the wireless technology of the Kidde RF-SM-AC will spread the alarm to the rest of your circuit, warning you no matter where you are. This device is UL listed and compatible with any Kidde alarm devices, allowing you to create a wide range of protection no matter the size of your area. One last thing just make sure you set all the same codes in all your wireless smoke detectors.

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

The max distance between any two onelink devices is 50' using their mesh network as long as one device can reach the next and so on then the signals will report through out the network of detectors. I have a 4000 sq ft multi level home with 5 levels and they area all interconnected without issue. System works very well I recommend the combination detectors for children's bedrooms or sound sleepers as they talk and seem to do a better job waking up kids and everyone else. That is not to say the other standard alarm detectors are not loud, but my observation.

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.

You should need only one receiver. You can program it differently for each sensor - up to 4 my base unit.

I'm going to say no, but I could be wrong. It's a very simple system, and exhibits no capability, that I've read about or otherwise discerned, beyond a basic motion detector/transmitter that's factory radio-paired to a basic beeper. The only electrical connection is a jack in the transmitter for an optional AC power cord. The instructions discuss only getting power to the two units (battery), transmitter placement, and that's about it. Works wonderfully and as advertised, just isn't a scalable system.

I found that the connector on the wires was a little difficult to seat in the receptacle on the smoke alarm. You might look at the connector to be sure that the pins didn't bend. There is a "key" on the connector and the receptacle so that it should only mate one way.Also, did you put backup batteries in the alarm?Did the green light work in the old alarm?
