DE9320041U1 - Alarm phone - Google Patents

Description

The system can be designed using either analogue or digital technology. The telephone - also in connection with extensions in the property to be monitored - uses the built-in microphone or discretely mounted, additional microphones to acoustically monitor the property. This monitoring is only possible if the alarm function is programmed and activated. By pressing a programming button (P) on the telephone, it is normally possible to store speed dial numbers. On the alarm telephone, the P button is pressed twice, or another button, e.g. α button (A = alarm function), to enter the alarm target numbers. After completing the input, confirmation is entered by pressing the programming button again. The alarm function of the device is then activated as soon as the motion detector, e.g. of a conventional alarm system, has been activated.

The system can also be designed to be wireless so that the intruder cannot easily discover it and put it out of operation.

If the property is broken into, the phone automatically dials the alarm numbers entered one after the other until someone answers (the owner may not be available at that moment, but one of his trusted contacts or the police may be). As soon as the person called picks up the receiver, the microphones in the monitored property are switched on and, after a synthetic voice on his alarm phone announces: "Alarm - connection (followed by the connection number)", he can listen to whether any suspicious noises are being made there, so that he can immediately take appropriate measures to prevent or deter a break-in.

For telecommunications law reasons, the alarm function is only possible if the motion detector(s) have been activated, i.e. when no authorised person is in the house. In alarm mode, i.e. with the listening microphones switched on, the telephone can receive incoming calls and indicate them by ringing

signal, however, for telecommunications law and data protection reasons, it is not possible to have the call as long as the alarm system is activated. In this case, when you pick up the receiver, you will immediately hear a busy signal, which is also transmitted to the person called with a slight background tone, so that they can tell that the telephone receiver has been picked up.

The alarm telephone system can be easily constructed using the resources available at the state of the art. Among other things, a microprocessor with RAM is required.

5. The advantages

of the plant are

that in the event of a break-in, an alarm is triggered that is either not or difficult for the burglar to perceive, and

With police protection in residential areas continuing to decrease, optimal property protection is guaranteed using state-of-the-art technology.

Claims (3)

1. Protection claims
General term: Alarm phone 2. Characteristic part: Alarm telephone system, characterized in that it consists of an alarm telephone in combination with a connected motion detector and, if necessary, externally mounted microphones, whereby the telephone device combined with a motion detector (infrared or ultrasonic) which, after appropriate programming by the user, automatically activates one or more microphones connected internally or externally to the telephone in response to a signal from one or more motion detectors and causes the telephone to silently dial telephone numbers stored in it of people to be alerted (e.g. police) one after the other until a person called answers and can listen in on what is happening in the house. 3. Subclaims for further developments of claim 1: System as claimed in claim 1) - also cordless or as a radio telephone of the C and D networks.
