In short, the idea is yes, and not wrong in itself, to construct a "noisy" security alarm handle for windows and patio doors, but that's basically it. Today I went very excited delivered to the Assembly, which had happened within minutes. With cross screwdrivers handle with two screws is quickly fastened to the patio door and the batteries are installed quickly. However, the first test was sobering and disappointing: the handle by closing the terrace door "sharp" then I made at the patio door vibrated until the alarm went off. I would say that the function of the handle is really properly; the alarm sounds at a certain vibration of the patio door promptly ..... but in a volume that does not deserve the name. As already reported in the heading to this Review: My smoke alarm is louder ... and louder though, because one hears, as opposed to this Schellenberg alarm security handle, all over the house!
Well, the handle is mounted, and must remain at the patio door .... but if he is in the case of the case actually scare away burglars, I must doubt arg. And that I could possibly be woken up by the alarm (my bedroom is just not right next to the patio door) ... no .... I can definitely rule. A sense of higher security can I handle this in any case not convey.
