Abstract

The utility model relates to an anti-theft informing apparatus whose automatic informing control circuit is composed of a dialing circuit, a number setting keyboard, a speakerphone circuit, a system control circuit, a reset button switch, a trigger circuit and an outer control switch. While in use, the anti-theft informing apparatus is connected in parallel with an outside line of a telephone, and to-be-informed telephone numbers and information are set. When a house door is pried open by 2-3 mm, the circuits work and dial through a set telephone to send out alarm messages. A thief pried the door into the house can not do anything even if the switches and the circuits are destroyed, because the information has been sent out earlier. The utility model does not influence normal telephonic communication or need to modify the existing telephone set, and has the advantages of high sensitivity, reliable work, economy and practicality.

Description

Antitheft notifying device

The utility model provides a kind of antitheft notifying device that utilizes the program-controlled telephone communication network to carry out burglar alarm.
