Question: I want to put this smoke detector in a bedroom, does it have a light that stays on all the time?
Document: very nice small smoke detector will fit in areas that a normal size detector will not fit. I will buy more of these later
I tested this unit with Smoke Check, which is a spray smoke for testing smoke alarms (pushing the TEST button is for the battery, not the smoke detector function). It picked it up fairly quickly. Easy to install, not too bad looking. Overall, a good purchase at this price. I have other brands, and this one performed just as well. Kidde makes great fire products.
I ordered these because they were inexpensive and I wanted to put several around my house. They work just fine and are not so sensitive that when I burn my toast they go off and won't shut off, which was the problem with the last ones I had.
This smoke alarm, made by kiddie felt fairly sturdy, seems to work well. It is about 4 inches in diameter - I used it to cover an old smoke alarm hole.
This smoke alarm is a very good investment for my home.The smoke alarm sound is loud and clear when smoke is present. ( I have it place near the kitchen)I do recommend Fire Sentry i9040E Smoke Alarm.
We found this to go off all on its own no smoke not pleased.
Very pleased with these smoke alarms. Very reasonably priced and seem to be doing the job. Very easy to install
Product did not work, I changed battery and still did not work. Do not buy this product. It will need to be returned.
Certainly cheap enough and easy to install. I needed it to replace an older one that stopped working after 15 years.
Basic small unit that is plenty loud to protect yourself and family. Durable unit that should be replaced every few years to insure effectiveness. All smoke detectors should be replaced every few years due to natural life of sensor units that age with household use. Durable enough to trust in home or RV. Inexpensive enough that there isn't any excuse not to have one in every room on every floor.
Answer: yes
