Home is monitored by an alarm company. Click to Enlarge 18.7 KB Link to comment Share on other sites More sharing options...
John Kogel Posted August 7, 2012 Report Share Posted August 7, 2012 CO detector maybe, smoke detector, more likely, alien spacecraft, possibly, but far less likely. [] Link to comment Share on other sites More sharing options...
Mark P Posted August 7, 2012 Report Share Posted August 7, 2012 It is probably a heat detector used to the alarm company. They use heat detectors instead of smoke detectors so they don't get notified everytime time someone burns their dinner. Link to comment Share on other sites More sharing options...

Tom Raymond Posted August 7, 2012 Report Share Posted August 7, 2012 Commercial heat detectors are fire detection devices that sense heat produced by combustion. In general, there are two types of heat detectors. First, there is Fixed Temperature. This means that once the heat reaches a certain level, the detector will trigger an alarm. Second, there is Rate of Rise. This kind of heat detector reacts to sudden changes in temperature from the starting set temperature. Each type of heat detector has its advantages, but it should not be said that one type of heat detector should always be used instead of another. However, the most sophisticated of commercial heat detectors are activated by both types/conditions. Commercial heat detectors commonly have a label on them that says "not a life safety device". That is because heat detectors are not meant to replace smoke detectors. Rather, a heat detector should be placed where smoke detectors should not be installed, such as in a kitchen, laundry room, or in a utility room. A commercial heat detector can help save a life, but a combination of heat detectors, smoke detectors, and a sprinkler system could save your business and save thousands of dollars worth of damage. Rob, it looks like yours came from India. Scroll to the bottom: http://www.bing.com/images/search?q=hea ... 77&first=1 Link to comment Share on other sites More sharing options...
John Kogel Posted August 7, 2012 Report Share Posted August 7, 2012 http://www.bing.com/images/search?q=hea ... 77&first=1 Well, that makes the alien theory more feasible, [] but I will stick with smoke detector. As opposed to smoke alarm. There is a difference, although most people use the terms interchangeably. Link to comment Share on other sites More sharing options...
