Cheap call system for seniors with minimal "reconstruction effort"

Did the bell bought as pager for my mother in law (in the same house). The bell is always there plugged into an outlet where we happen to be, the actually foreseen for wall mounting bell was fitted with a loop and now worn by lanyard around your neck. The housing of the doorbell is easy to drill with a thin drill, so that you can run through a thin nylon thread. The bell itself is flush with the housing, so that accidental discharge is likely to be very rare. Each time triggering occurs directly in bell housing feedback via LED, you can see so that the signal is gone out. The rounded shape of the bell housing is comfortable to wear. The range of the radio signal goes from the 1st floor of the house to the basement and the garden. The "misused" use of these wireless doorbell is the optimal solution with respect to a telephone notification inside the house for us because while every now and then before the answering machine is turned on and then the emergency call goes nowhere phone. A battery need only the portable doorbell. The batteries are available at Amazon in a double pack at a budget price.

Who is looking for a simple alarming way inside a house gets here with minimal customization a good and extremely cost-effective solution. But as simple doorbell good for the part of course ;-)
