Abstract
The utility model discloses a theftproof automatic dialing telephone for a dwelling house, which belongs to telephone communication equipment for users. The utility model is characterized in that the connection point of a relay J of the automatic dialing unit is connected with a loud-speaking talking key, and a switch K1 is connected with an alarm and a delay circuit I. Besides, a switch K2 of a delay circuit II is connected with a memorization dialing key, and a switch K3 of a delay circuit III is connected with the telephone number store position key. The utility model has the characteristics of simple structure and reliable alarm. When a theft occurs, the theftproof switch and the loud-speaking talking key are communicated, the alarm is then actuated and communicated with the memorization dialing key which can dial out elephone numbers in the telephone number store position key, and thus the dual alarms of a site and a long distance can be realized. The utility model is particularly suitable for unmanned shops, secrecy rooms, bins, etc.
Description
The antitheft automatic dial telephone set of dwelling house belongs to the telephone communication set that the user uses.
In the common burglar alarm, existing audible alarm, light warning also arranged, or the two has type of alarm concurrently, though can bring into play anti-theft alarm function, so mostly be onsite alarming, effective range is little.CN2277606Y discloses a kind of telephone set automatic antitheft warning adapter, by the anti-theft signal generating means, control circuit and warning circuit are formed, and the external tapping by adapter combines implementation language with telephone set and reports to the police, but the circuit structure complexity, and warning still is an onsite alarming.
The purpose of this utility model is to provide a kind of simple in structure, reports to the police reliable and can realize the antitheft automatic dial telephone set of dwelling house of long-distance alarm.
The utility model is to realize above-mentioned purpose like this.The antitheft automatic dial telephone set of dwelling house is combined by telephone set and able to alarm, automatically dial device, is provided with and K switch in the able to alarm, automatically dial device circuit
