A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and / or visual alarm from the detector itself 2. Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimeters (6 in) in diameter and 25 millimeters (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery How to Test Your Smoke Detector: 1. Test your smoke detector once a month 2. Press the test button on your detector and check that the device beeps or rings loudly 3. Lighting candles under the detector to see if the alarm goes off. Repeated use of smoke to activate detectors can cause them to fail when a real fire occurs ###Package Includes 1 x Home Sensor System Wireless Smoke Detector Cordless Security Fire Alarm 2 x Screw ###Extra Info Note: If your detector runs on batteries, change them when you change your clocks - at the start and end of daylight-saving time 1. If your smoke detector starts chirping or beeping off and on, it′s time to change the batteries 2. You may want to consider purchasing a combination smoke / carbon monoxide detector. These units cost more but are well worth it 3. If a smoke detector goes off, you literally have seconds to respond. There is absolutely no time to gather possessions, pets and possibly even each other. Your best response is to leave your home immediately, gather at your prearranged meeting place and call 911 from a neighbor′s home 4. Avoid getting any paint or dust on your smoke detector 5. Make sure the smoke detector you choose has been tested by an independent testing laboratory * 6. Replace all detectors after 10 years

Ordered 2 and none of them worked. I bought two units of this smoke detector. The most reason was the low price. I have had some smoke detectors, so i know how they work, and when you would change then. They arrived in a single plastic envelope. Which results in that both orginal boxes were crushed and broken(open). Still both detectors were intact. Nothing broken. So I started testing. I inserted the batteries and (let us call them unit 1 and unit 2), unit 1 when i inserted the battery eveyrthing went well. The light flashes every 60 seconds, so you know it is working. Pressing the test button, you hear the alarmsound for a couple of seconds, so until here it is OK. Unit 2 is a different story, the moment you insert the battery, the testbutton starts to flash for 4 seconds and then the alarm goes off. So here you can not even test with the testbutton. I tried it even with the other battery aa I thought it might be the battery. Now as unit 2 is impossible to test, I wanted to test unit 1. So i light up a match and put it out, the smoke should set the detector on.... Well it didn't So I took a newspaper and set it on fire so it made enough smoke that it should set it of. And when I mean a lot of smoke, I mean so much you couldn't see at 1 meter. I needed to open the windows for 15 minutes to remove all the smoke. Luckly nobody called the fire brigade:-) So unit 1 and 2 are broken for me. I contacted right away the chat of TMart. And after chatting for 5-10 minutes I got an answer they would mail me tomorrow a mail as they should take to the bosses/responsables, yo see what they would do. Which surprised me a bit. I mean, they send me two broken units, where is the questions so they have to ask first another person for it. A big disapponting for me. So that was a big surprise, it never happens with MiniINthebox when this happens. They send a replacement right away. Oh yes, both batteries were 100% full charged. So until now I am unlucky in the product and also the post-sales. Hopefully they will resolved the problem. And one thing more:why do they ALWAYS send your order in a plastic envelope and never in a box, when it is fragile? When i buy at MinInTheBox they send eveyrthing in a good packed box or bubbledenvelopetranslate
