  1. They'd also installed your original detector in a "sub optimal" position. They are designed to be installed horizontally on a ceiling for maximum efficiency. And preferably NOT in a corner of a room or if mounted vertically on a wall, adjacent to the ceiling, as both positions are relative "dead areas" where smoke tends not to fill until the fire is more developed. And of course for detection EVERY second is important and can easily mean the difference between life and death.

  2. Same here... "smart" my arse !!!!

  3. Good GOD !!! I HATE the bloody "smart wipers" (NOT) on my car. Flick them on when a few spots of rain falls and they manically BLUR as ther wipe at about 10 revs per second (probably depositing a few microns of blade rubber onto the windscreen in the process)..... 2 minutes later when its pouring down they then decide to intermittently wipe once every 30 seconds. Just give me an intermittent wipe that I control the rate of, like they used to !!!!

  4. No thats now just the cost of the electricity that they use. F*ck corporate globalism.

  5.  @mixit2413  Putting a smoke detector half way down a wall in a tall room is potentially inviting yourself to an early "death by fire". The truth is its actually MORE important to place a detector on a ceiling in a high room. Let me explain. Have you heard of "convection"? Heat and smoke from a fire source rise vertically indoors until they hit the ceiling and then "mushroom out" horizontally but due to their inherent thermal energy they remain at the ceiling level. As more and more heat and smoke rise upto the ceiling the smoke level slowly descends (it really does form a clearly visible thick layer of smoke at the top of the room), and to have a detector halfway down a tall wall means that by the time the smoke level reaches down far enough to activate the detector, the fire is now well developed and potentially the room is in the early stages of a "flash over". In a high room, the delay between the fire starting and the detector (halfway down the wall) triggering is greater due to the longer time it will take to fill the top half of the room with heat and smoke. I'm telling you this to help you avoid danger... not to be a "smart arse". Graphic demonstation here.... https://youtu.be/_wO7IckIdA0?t=149 And a physical demonstation here .... https://www.youtube.com/watch?v=BtMmymOxdjc (the smoke detector in this demo is on the ceiling, doing its job as it should). (P.S I was a fireman and fire safety officer for 30 years btw)

  6.  @mixit2413  All UK fire brigades (including the one I served in) have fitted domestic smoke alarms (battery powered obviously) across the whole of Britain for at least the last 20 years, and I have personally fitted more than a couple of thousand over that time. The safest placement of detectors within a single dwelling is to cover the "means of escape" I.E in a standard domestic property that means the hallway, stairs and landings, with the additional strong advice that room doorways are to be closed last thing at night. The problem with placing a detector in individual rooms is that when a detector activates during the night, the natural reaction of a roused occupant is to open the door to the room where the sound is coming from, with potentially fatal consequences from the release of overpressured heat and smoke from the room overcoming the person, or potentially even a "backdraught". There is NO "optimum height" down a wall. The optimum height is ceiling level, anything "down a wall" is "sub optimal" to use the content creator's choice of phrase. What I have said in my earlier reply regarding the heat/smoke barrier at ceiling height gradually descending as the fire develops is absolutely correct, to argue that it is acceptable to place detectors on walls in tall rooms to make it easier to test and service them is VERY bad advice, and may lead people to make potentially disastrous choices when they fit a smoke detector. When they are fitted on ceilings in tall rooms it is recommended that they be tested with the use of a broom handle, most detectors nowadays even have large, dished test buttons specifically for that purpose.
