X-SenseWireless Interconnected Smoke Detector, Fire Alarm with 10-Year Battery Life and Transmission Range of over 820 ft, SD20-W, 3-PACK

These were purchased to extend an existing X sense network.They interlinked perfectly with the existing units.Manufacturer's instructions were easy to follow advising on where to locate as well as how to install.

easy to install and link together and with the heat alarm. Tests ok but haven't tested with smoke. The units are a lot larger than the ones I had before, I don't know why they have to be quite so big as it's mostly empty inside. Let's hope the batteries last as my last FireAngels were rubbish.

Very quick delivery, well protected items as described.

Simple to fit and interconnected (if one goes off they all go off). Hopefully I never find out if they work. They tested okay so fingers crossed if we have a fire they wake me up.

There is no central hub, so the signal travels from one to the other via its RF signal (not Wi-Fi). So, with this in mind, I could cover a sizeable 4-floor house ( 10 detectors). Before you permanently fix them, you can put them around and test the coverage. I can't say about the battery life yet.

This 3 pack of smoke detectors is well made and very easy to set up.Each alarm is a standard size with a diameter of 12cm and they stick off from the ceiling about 4.5cm so big enough to cover any older ones you might be replacing but does look huge. I like the design of how easy they are to mount with just 2 screws and plugs if required to attach the base plate to the ceiling and then you just screw lock the alarm onto the base plate which then pushes the button in to activate the device. All three arrive paired to each other so I didn't have to do anything to connect them up and I tested one when I burnt the toast which was nice and loud.I do wish they were app based with WiFi connectivity so they could also integrate and connect to my X-Sense house security system, and it would be nice if they could give you air quality readings as well.Overall, at £78.99 they are a good price for 3 alarms I just wish they could do a little more and integrate a bit more.

I had no problem in installing these. The instructions were clear. There is a swich on the back which enables the battery to work. This must be pressed if the unit is to be tested. I found it easier to put it in the holder to rest the unit. Also, there is a slight delay between pushing the test button and the alarm sounding. Originally, I thought the unit did not work because I expected the alarm to sound as the test button was pressed which it does not.

Less than a week after purchase and installation, one of them suddenly beeped twice, checked the manual and said it needed to be replaced. Now I have to remove all installed sensors and return them.

Die Raumelder machen einen qualitativ hochwertigen Eindruck. Das installieren und vernetzen ist sehr einfach und gut erklärt (auch mit Video). Gibt mir ein gutes und sicheres Gefühl, ich hoffe die nie im Einsatz haben zu müssen...

Leicht zu installieren

stolzer Preissonst war alles okaykeine Probleme

Die Funkrauchmelder sind wirklich klasse. Natürlich sind Sie nicht billig, aber ich denke, das Geld wert. Habe natürlich noch keinen "live"-Einsatz gehabt (zum Glück!), aber die Rauchmelder machen qualitativ einen top Eindruck. Die Einrichtung ist sehr schnell gemacht (das "Koppeln" der Rauchmelder ist absolut easy) und auch für Laien problemlos durchführbar.Die Montage ist simpel und eine hervorragende Beschreibung liegt bei.Ich habe bei mir 8 Stück verbaut und getestet - arbeiten in der Testfunktion einwandfrei - jeder einzelne. Hab das durch die Funk-Fernbedienung (extra erhältlich) erweitert, und auch die ist top.Kann ich gesamt also nur empfehlen. Mal sehen, ob die sauber die 10 versprochenen Jahre durchhalten :-)

Alles TOPTun, was sie sollen.Installation und Synchronisierung, sowie Einbindung der Fernbedienung sind einfach.Nach 10 Monaten hatte ich ein Problem mit einem Melder (10 Jahresbatterie nach 10 Monaten fast leer). Der Service war gut zu erreichen und ich habe sofort ein Austauschgerät erhalten.Mehr kann man nicht verlangen. Der Service bekommt von mir auch 5 Sterne.
