Kidde i9040 Fire Sentry Battery-Operated Ionization Sensor Compact Smoke Detector Alarm, White, Pro

Simple to install and batteries seem to last and last, but when they're low, it chirps to let you know. It does not look too obtrusive either, which is good as some smoke alarms can be quite large and ugly to look at. I don't see any reason why you should be concerned as to the reliability of these, but if you are, then you could mix brands of smoke alarms around your house. I would highly recommend grabbing some if you don't have any and while you are at it, look at buying some 9v batteries off Amazon to stock up.

Good smoke alarm at a very good price, seems to work well when testing and the battery is not a pain to put in, unlike my last one which was most definitely tricky. All in all happy with my purchase and i would buy another.

Got this, didnt use the little raw plugs and screws it came with as I already have a little hook in place (to replace my old one). This seems to work well ie not go off when I slightly burnt my toast. press the test button all seems fine. quite discreet. Will never know how good any smoke alarm is until it goes off for a fire - which I hope I never find out. However im pleased with this purchase.

All homes should have a smoke alarm as a matter of safety, several in fact and I did indeed already have 2 fitted. They were not wired to the mains and were battery operated, but the problem with battery operated smoke alarms is their limited battery life. What drew me immediately to this superb smoke alarm was the 10 year battery life! The unit comes complete with its own built in Lithium ion battery. That’s very impressive to say the least and leaves you feeling safe and secure once its fitted. Mine is now fitted upstairs and I know I don’t need to worry about its battery for a decade. Excellent! It arrives simply boxed and includes a comprehensive instruction leaflet that advises on how to fit it, where to fit it and also it ships with 2 screws and raw plugs to enable you to fit it. One thing I learnt when I read the instruction leaflet was that Photoelectric smoke alarms are better at detecting and alerting you to slow smouldering fires that smoulder for hours prior to bursting into flames. I felt extremely reassured by this information that prior to reading that leaflet, I didn’t even know! I like the fact also that the unit has an operating LED light which flashes every 53 seconds to confirm to you that the unit is working and protecting you and there is also a low battery warning alarm ( beeps every 40 seconds) which I haven’t actually heard as my unit is new but I’m glad its there so that when my alarm battery is running low I will be aware enough to do something about it rather than leaving me unprotected.

After moving to a new home and realising there were no smoke alarms at all, I had to get some quickly. With all the expense of moving I didn't want to break the bank. However, I wanted something quality that would work. After looking around in local shops Kiddie seems to be a very popular brand, and I've seen this smoke alarm a few times at a higher price. It was a good bargain and it arrived within two days, which I thought was brilliant. I also bought the Kiddie carbon monoxide alarm. They were both easy to get in place and came with batteries. No fuss needed.

This works great, house still hasn't burnt down, and nobody has died of smoke inhalation. I remember this time my neighbours house was on fire at about 1am, and I could smell it come through the walls so I ran outside and absolutely hammered their door down trying to wake them up, and the neighbour opened the door and I said "your house is on fire" and she replied "I don't think so..." while her stairwell was so full of smoke I couldn't see past halfway the stairs. Turns out they never checked the batteries in their smoke alarms, and also I was right and their house was on fire, but the fire services dealt with that in the end. Seriously, everyone needs this in their home, and needs to make sure it works. I mean, not necessarily this smoke alarm specifically, but get a fine smoke alarm. It is 10 quid and saves your life. Why is this something people even need to be told?! I'm just saying, I don't live next door to all of you, right? That would be too much to ask.

The smoke alarm is quite neat and unobtrusive, comes with a battery and all screws and plugs needed to put up. A mounting plate is screwed to wall or ceiling then only a small twist is needed to secure main unit to mounting plate. Had 2 for a month and one went off when someone left open bathroom door after showering. Unit about 1 metre away! Then one night 3am the other went off at random without cause. There's a hush feature on these units so easy to cancel without taking battery out. Knocked off a star because of the last random going off. Only done it once in a month! I would recommend this product for the cost and peace of mind.

Its a smoke detector that doesn't go off at 2AM when there is no fire (the unit this replaced did) or when I grill sausages - which as we pretty much forced to have these horrid devices that seem just cost money, annoy us by going randomly, causing us to risk falling off ladders/chairs to deactivate them as they are mounted high on ceilings this - is an excellent feature. I've yet to have a situation to test its true 'house fire detection' ability and am not planning to change this any time soon.

Does what it is supposed to do. Very easy to install.
