Wide-range usable telephone alarm

Abstract

The invention relates to a wide-range usable telephone alarm and belongs to the technical field of alarms. The technical scheme is that the alarm is composed of a power supply, an alarm phone and an alarm start portion which are used in a wide range. The power supply portion is specially designed, the power supply has many different points from traditional design and can work normally under the low voltage, and elements cannot be damaged under the high voltage, so that the electrical product with the special function has high adaptability, and the product application range is improved greatly. The telephone alarm is created through a communication telephone, a plurality of groups of leads are led out of a copper foil matrix of a telephone dial key printing plate, and the telephone alarm is matched with a prior patent and achievement to be an excellent telephone alarm. The alarm start portion is that a start apparatus is added at a key position of a door to solve the alarm start problem scientifically. Under the matching of the prior patent and achievement, two alarms can be started during people crime committing, alarm can be emitted in field, and outside staff is alarmed through the network simultaneously.

Description

technical field [0001] The invention belongs to the field of alarms. Background technique [0002] "Security" is an important symbol of the happiness index. An alarm with excellent performance can protect the most basic cells of the society. It will be respected in a society where work is stressful. [0003] However, the current alarm equipment mainly has the following deficiencies and needs to be further improved: [0004] One of the adapted range of the used power supply also needs to be improved. The reason is that because the present invention is a security equipment, the working stabilized power supply is a key part to determine the performance of the product. The first reason is that the power supply part involves factors Many are fragile parts, which is a common problem in electronic devices. Second, the quality of the power supply voltage regulation directly affects the performance of the whole machine. The present invention belongs to security equipment, which is...

Problems solved by technology

Obviously only using traditional three-terminal integrated circuits as a power supply cannot achieve

[0005] The second is also a very important point. Although there are many alarms in the current products, there are two biggest weaknesses. The first is that they do not have the most important basic function of keeping people outside the house.

The second is that the sensors of its alarms usually have such weaknesses that there is a possibility of false alarms

However, solving this problem requires the combination of multiple technologies and technological innovation. It has been difficult to break through for a long time, and it has not been properly solved.
