I myself am actively driven emergency in the fire service and for a long time. After we had a bet where we could involve an entire family nurnoch dead as an old lamp began to burn, and the wife, and 3 children died of the typical smoke inhalation and then burned, I have decided now to reinvest and my networking smoke detectors throughout the house. Currently I am studying, however, and did not use a lot of money to me in the existing detectors expensive RFID chips, so I was looking for cheaper alternatives to hedge around the whole house. With this set, I then tried it. First lot to me that all smoke detectors were packed clean and could be networked's play. The alarm forwarding works perfectly, regardless of whether the test mode or with a test spray (simulated real alarm). Even through the thick steel door of our boiler room with concrete ceiling, the signal comes out clean on the whole house. With 6 smoke detectors I have now secured the important areas. Currently, my sole negative point of criticism that some inaccurate product instructions. The installation of the detector is clearly described how to disable an existing alarm, however, is not experiencing the best of intentions, because trying is called for and that is with 6 detectors simultaneously strike already enormously unpleasant to the ears ;-) That's why only 4 stars , I can not say anything about long-term experience, but right now I'm very happy with the detectors. For each of the money not immediately hundreds of dollars for professional has networked radio systems issue a clear recommendation. As I see it you're with these detectors also well protected. Is just very important that you make yourselves clever where you install the detector. Best ask the expert, since the detectors have a tolerance and you the Gepfeiffe brings nothing if all escape routes are blocked already ;-)
