After I unpacked the wireless smoke detector and read the description and programmed a "master", I was well advised, first of all take the smoke detector in the various rooms. Here I have found through several functional samples that in brick houses removal may not be very large and the "Master" as the center of the positioned around it must be "Slave's". If this is not observed, there are always times no signal from the "slave detector" to "master" and thus not forwarding to the other "Slave's". Likewise, there can be no signal from one floor to another, when a reinforced concrete slab in between. Here I have chosen the transfer in the hallway. Then I have all fixedly mounted on the ceiling and once again performed functional tests of all indicators made. After considering all these limitations, this wireless smoke detector work perfectly; let's see how long it takes until the battery / batteries are empty.
