Can these be operated without linking them together?

Yes they are battery operated and can be placed wherever you want in your house and don't have to be linked together.
794423
Yes. They can operate independently of each other. If you choose to do this, I would purchase regular smoke alarms at a lower price.

The short answer is, no, they are not set-up for that. However, if you're perhaps very handy and mechanically inclined, it appears to be possible, BUT, you have to also consider that you're reducing the amount it can support by more than 1/2 of ONE unit.

They're not designed for daisy-chaining them, but they're easily modified with a matte knife or box cutter. With that you could connect them with packing tape.

No. You have to connect bare wires together, but it's easy. They give you little caps called "wire nuts" that let you just twist the wire ends together.

Yes you can. It needs some very little configuration. You should be able to do it following the set-up instruction. I use it for similar concept.

Unfortunately no they cannot. They use clips shaped like a triangle that requires three to be placed in triangle shape. You could just set them there but they would not be connected.

The are already connected. You just have to run them under your dash. Also, they're long enough to do so, and color coded. So, when you disconnect them to run them, there wont be no confusion.

No they are attached. I'm sure if you wanted to break them apart you could.

You can have them plugged in, but you will not be able to use them at the same time unless a program let's you select the output.

You can't string them together, but as long as you space them to be able to reach the on/off switch, you really don't need to. They are solar powered so no plug in required.

You have to pull them away from each other and then you can connect them together. It's like they are on a spring. One end goes into the other end. It takes a little muscle!

yes they can connect 1 time, but the snap hardware that connects them is only applicable once and you cannot back it out once inserted. You could possibly cut it off if you connected just to use 2, but couldn't use that same hardware again. you would have to use a bolt and nut purchased separately to reassemble once you removed. The height is also adjustable if you get hanging L sold separate. We use these in our cubicles and they work pretty well with L attachments.

No, it will only allow operation on one or the other not at the same time without coding.

You don't need to connect them to each other; each has its independent solar/battery power source. The only connection required is, if you want to hang them, you need a bent wire, piece of string, or whatever you can devise to attach them to whatever you want to hang them from. Easy.

Yes you can, all you have to do is set up the pin matching each other and is good to go.

I don't think that would work. I can't see how you could safely connect them and have it remain stable.

It's not on a system. They are not connected in any way, which is unfortunate because you are pretty much guessing which one was rung first. Yes you can add more to them.
