3x Nemaxx WL2 wireless smoke detector smoke detector interconnectable - according to DIN EN 14604

Great for the price! Set up easy - there are now English instructions included in the box. Came with all the batteries and the set up was easy to make them talk to each other. test is easy too - hold down the test button on one for about 10 seconds then all the others alarm for about 10 second to prove wireless connection/battery. according to the instructions there are early warning bleep variations for comms or sounder battery low although mine have only been in for about 6 weeks so hoping I do not hear that in the near future.

Good product. Only issue is that they need to be screwed to the ceiling - unlike previous non-connected alarms which I've been able to attach with double-sided foam tape.

This is the second order of these smoke alarms that I have purchased as I like the idea of linked alarms if a fire breaks out anywhere in the house. This set did not turn up with any batteries which means I now have to buy four AA batteries and one 9v battery per smoke alarm, an additional expense I did not expect to have. Its too much hassle to return the smoke alarms so I just won't be purchasing anymore .

Very easy to pair up and install. Came with batteries and instructions in English. When tested with real smoke - the detector in the lounge went off and the other two on the first and second floor in an attic dormer also went off straight away - the noise was so piercing it would make you want to get out of the house. Appear to be very effective at alerting the whole house to a problem. They can only be silenced by pressing the test button on the 'master' alarm - and then they all go quiet. They cannot be silenced from any of the other units which is a good safety feature.

In principle, a great product. Once you get used to the instructions (which are not easy to follow) you can get up and running fairly easily. Trouble is, after a few months we found most people in the house were removing the batteries to stop them constantly going off - often in the middle of the night!A great idea in principle, and if they didn't give false alarms, I'd happily recommend them. But not right now.

I don't normally bother writing reviews, but I've had two 3x packs of these as I thought I might have just been unlucky the first time around but it appears not.So firstly, they need a lot of batteries (3x AA and a 9V) and they get through them quickly, to the point where I've bought rechargeable batteries to help their thirst for power.Secondly, and most annoyingly, after about 6 months you will start to get false battery warning beeps. Swapping all the batteries won't help and the unit at this point is pretty much ready for the bin.This has happened to at least 3 of the 6 purchased. I've tried various different batteries and they all go the same way. Which is a shame as its not a bad looking unit and the fixings etc are pretty neat. Just a shame they are not very reliable.

These arrived slightly earlier than expected and were well packed and complete with all fixings,batteries and instructions in english.Setting up was very straightforward and so far all is working as expected in our four bedroom house with the detectors spread across the full length of the property.The smoke detectors (which are larger than most) have a removable mounting plate which makes for easy fixing and setting up. The build quality appears to be good and the alarm is appropriately loud.

Good product.
