Abstract
The utility model provides a multi-entry lock-control anti-theft alarm which comprises a double-tongue door lock, an entry detector, a lock controller, a control circuit, an alarm circuit and a power supply. The multi-entry lock-control anti-theft alarm is characterized in that the lock controller is arranged in a lock buckle box of the double-tongue door lock. The entry detector which is installed on a door and a window is composed of a breakage action type detector and a general action type detector, and a breakage limiting sheet is additionally arranged on a common switch of a door or a window to form the breakage action type detector. When the door or the window is forcedly pushed to open, the switch of the door or the window mutually contacts the breakage limiting sheet. The multi-entry lock-control anti-theft alarm has the advantages of simplicity, practicality, low false alarm rate, low cost and low electricity consumption. The multi-entry lock-control anti-theft alarm can also prompt a user to well close the door or the window. The utility model can be widely used for places such as a family, an office, etc.
Description
The utility model belongs to the lock regulation burglar alarm, particularly about multiple entry lock regulation burglar alarm.
At present, the inlet formula burglar alarm kind that is applicable to occasions such as family, office is a lot, but most function singleness, the rate of false alarm height, disguised poor, be easy to destroyed, influence it and promote the use of, simultaneously, multi-user's formula alarm generally adopts central control unit and utility power, though function is more powerful, as go to pot or self fault makes the total system paralysis easily.
The utility model purpose is that rate of false alarm is low for occasions such as family, office provide powerful, is convenient to install and use, and is difficult for ruined multiple entry lock regulation burglar alarm.
The utility model is realized by following measure: it comprises two flapper locks, inlet detector, locking-controller, control circuit, circuit for alarming and power supply.Its special character is: locking-controller is installed in the keeper of two flapper locks, the inlet detector that is installed in door and window constitutes with general action type detector by destroying the action type detector, destroy the action type detector and on common Switch for door and window, install destruction qualification sheet composition additional, when door and window was pushed open by force, Switch for door and window itself limited sheet with destruction and contacts.Locking-controller comprises two contact switch K
