ELRO FS1801 | 10-Piece Smoke Detector Set | 10-Year Sensor | Complies with European Standard EN14604 | White | Set of 10

Decent smoke alarms that are straightforward to install and set up. The pack of four is handy for covering multiple rooms, and they are compact and unobtrusive on the ceiling. They test correctly, comply with EN14604, and the alarm sound is loud enough to be clearly heard. Overall, a good value, no-nonsense smoke detector set.

9V battery 🔋. Nicely packaged so they don’t get scratched & battery is wrapped & not connected, the 9V battery also has to installed so it activates the device. Good crisp sound and smaller then other, the red light flashes that behind the white case every 34 seconds yes I used a lapse timer to get the correct count.. used in my loft & mobility scooter shed, in the airing cupboard & one spare. For the cheap price they can save you a full on fire 🔥 before it gets too bad. Replace the 9V battery when it start to peep or 2 years at somewhere close or loft use every year so you know it’s going to work, do a sound check to hear the speaker works as & when like a monthly thing, ping & touch first day of the month.

Three out of the four alarms worked but the fourth seems to have a problem!

More than happy with these smoke detectors. They are a very small detector with a loud sound when activated! The pack comes with 4 devices and each are individually wrapped in great condition. All I had to do was remove the wrapping from the battery, fit it to the terminals and then test the alarm! Each alarm comes with a packet of screws to mount on the ceiling or a wall - a simple method. The 'base plate of the detector simply 'drops into' precut grooves on the alarm and it then click neatly into place. The batteries can be replaced as often as necessary, not like some that come with a long life battery THEN you have to replace the whole alarm. Happy to recommend as good quality and a decent price.

Oh, with this prices, I’m happy to buy that one and really good item thank you

Small, neat, compact Smoke detecting alarms, i bought four for the various rooms in my home. The alarms come with one 9V battery each. This is helpful, they have intermittent flashing light, to let us know the alarm is still working. The alarm is very loud on testing. just what I need and want.

Nice size. They do take a bit of getting used to when trying to twist the detector onto the base. It's great that they come with the battery. When connecting the battery please make sure it sits flat when the battery is pushed into place or you won't be able to connect the detector to the base. The screws provided the head is too small
