Accompanying drawing is an electrical schematic diagram of the present utility model.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is made an explanation.

Embodiment: this alarm comprises A, B is connected to the input of telephone wire and puts in order to circuit, through the transformation of the way telephone set in by the voltage stabilizing circuit of forming by voltage stabilizing didoe VD0 with by integrated circuit (IC) 1, the code sender that dial is formed, and the radio pager of adapted, it is characterized in that being provided with information detection head M, door switch S and by the employing controllable silicon VS and the operating switch circuit formed of triode VT1 of their control, also be provided with the time delay monostable circuit that the back level is made up of integrated circuit 1/2IC2, another squarer of forming by integrated circuit 1/2IC2 of the counter of forming by integrated circuit (IC) 3, in addition, also be provided with by triode VT2, the simulation dislodging organic electronic switch that VT3 forms, and the simulant electronic switch of forming by integrated circuit (IC) 4.

When information detection head M is touched by metal object or door switch S when being opened, controllable silicon VS conducting, the operating switch circuit is opened, by resistance R 1, voltage stabilizing didoe VD0 sets up initial working power voltage and keeps controllable silicon VS conducting, each integrated circuit (IC) 1-4 gets electric work, square-wave generator 1/2IC2 the 13rd pin high potential exports the triode VT2 base stage of simulation dislodging organic electronic switch to, make triode VT2, the VT3 conducting, enter off hook state, the 12nd pin of square-wave generator 1/2IC2 is connected to the 3rd pin of time delay monostable circuit 1/2IC2 simultaneously, its the 1st pin is a high potential, through of short duration time-delay upset, the 1st pin becomes electronegative potential, one road pincers code sender IC1 the 9th pin is an electronegative potential, start code sender IC1 for treating the signaling state, another road is delivered to counter IC3 the 13rd pin and is counted, IC4 opens holder M1 by the control simulant electronic switch, it is the redial key of dial, make code sender IC1 the 11st human hair combing waste go out the paging signal of the 1st setting, the off-hook time is adjustable by RP, after signal effectively sends, when square-wave generator 1/2IC2 the 13rd pin becomes electronegative potential, simulation dislodging organic electronic switch turn-offs on-hook, produce the 2nd square wave through 2-3 square-wave generator in second 1/2IC2, the 13rd pin is again a high potential, repeating said process makes code sender IC1 send the 2nd (holder M2) setting signal, distribute until the 3rd (holder M3) setting signal, the 4th, the 5th, the 6th signal is bye, do not send information (provide dislodging machine usefulness during only for initial setting this moment, can save configuration switch), when the 7th counting beginning, counter IC3 the 11st pin is a high potential, operating switch circuit triode VT1 conducting, controllable silicon VS turn-offs, the entire circuit power cut-off.When house-owner enters, as long as at the appointed time (when the 1st signal do not distribute, be generally the several seconds, the Acknowledgement Tone time by the various places paging system is fixed, long-time as adding, holder M1 can be controlled by the 2nd signal square wave, all square wave time of pusher) press door switch S and locking, this moment, the b ' c ' position (charge position) by door switch S1-2 was back to a ' b ' position, force operating switch circuit triode VT1 conducting, turn-off controllable silicon VS, circuit is not worked, triode VT1 conduction period, information detection head M is inoperative, and (time is by capacitor C 0, resistance R 0 discharge decision), again when house-owner gos out, only need door switch S is ejected (circuit start at this moment, capacitor C 0 is in b ' c ' position charging of door switch S1-2), shutting the door at the appointed time, (door switch S1-2 is in a ' b ' position again, and controllable silicon VS is turn-offed in capacitor C 0 discharge, M is inoperative for the information detection head, non-locking can be realized when door switch is installed), house-owner is good with door lock, after treating that capacitor C 0 has been put electricity, entire circuit is in the alert state for the treatment of automatically.
