Abstract

If fly nets (1) on windows are cut, moved or pushed, a first fly net contact (2) presses on second fly net contacts (3) through a flex (1a) and current flows to an npn transistor (14). If a door bolt is sawn through, it falls on door contacts (5) and current flows to the npn transistor. If power lines are cut on cables (6), a sheet metal card slides into card slide (8) and current flows through all power contacts (9-11) to the npn transistor.

Description

Die Erfindung entspricht den Ansprüchen.The invention corresponds to the claims.

Sie basiert auf 3 npn Transistoren und 1 Selbsthalterelais.It is based on 3 npn transistors and 1 self-holding relay.

Es ist bekannt das Alarmanlagen automatisch die Polizei verständigt. Wenn allerdings ein Draht für z. B. die Stromzufuhr gekappt wird, wird der Alarm als Fehlalarm eingestuft.It is known that alarm systems automatically notify the police. However, if a wire for z. B. the power supply is cut, the alarm is considered False alarm classified.

Aufgabe der Erfindung ist es, Einbrechern den Eintritt zu verwehren, Zutrittberechtigte allerdings einzulassen. Sie sollte auch billig sein, da es sonst kaum Unterschiede zu den anderen "SUPER- ALARMANLAGEN" gibt, die 3000-4000 DM o. ä. kosten. Sie sollte nicht mehr als 1500 DM kosten.The object of the invention is to prevent burglars from entering, However, admit those with access. It should also be cheap, because otherwise there are hardly any differences to the other "SUPER- ALARM SYSTEMS "that cost 3000-4000 DM or similar. It shouldn't cost more than 1,500 DM.

Diese Aufgaben werden durch ein System aus Transistoren und Relais gelöst:These tasks are solved by a system of transistors and relays:

Es gibt allein durch das notwendige Fliegengitter an jedem Fenster einen Vorteil, der zwar nichts mit der Auslösung des Alarmes zu tun hat aber doch sehr gut ist: Es gibt 80% weniger Mücken im Raum (ohne teurem Insektenschutzmittel).There is one advantage to every window simply because of the necessary mosquito nets Although it has nothing to do with triggering the alarm, it is very good: there is 80% fewer mosquitos in the room (without expensive insect repellent).

Es kommt kein Unberechtigter ins Haus, ohne bemerkt zu werden. Wer ins Haus will braucht die Code-Karte (7).No unauthorized person comes into the house without being noticed. Anyone who wants to go into the house needs the code card ( 7 ).

Beispielexample

Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.Embodiment of the invention is shown in the drawing and is in following described in more detail.

Wenn ein ungebetener Gast versucht, auf unerlaubtem Wege ins Haus zu kommen, müsste er folgende Wege benutzen:If an unwanted guest tries to get into the house through unauthorized means, he would have to use the following ways:

< Durch das Fenster.<Through the window.

Wenn er das Fliegennetz (1) durchschneidet/dagegen drückt fällt/drückt der Kontakt (2) durch die Schnur (1a) auf die Kontakte (3) und es fließt Strom auf den npn Transistor (14) . . .If he cuts through the fly net ( 1 ) / presses against it, the contact ( 2 ) falls / presses through the cord ( 1 a) onto the contacts ( 3 ) and current flows to the npn transistor ( 14 ). , ,

< Durch die Tür.<Through the door.

Wenn er den Riegel (4) durchsägt, fällt dieser auf die Kontakte (5) und es fließt Strom auf den npn Transistor (14) . . .When he saws through the bolt ( 4 ), it falls on the contacts ( 5 ) and current flows to the npn transistor ( 14 ). , ,

< Durch Kappen der Stromleitung.<By cutting the power line.

Wenn er die Stromzufuhr z. B. an Kabel (6) kappt . . .If he z. B. on cable ( 6 ). , ,

< Durch Einschieben einer Blechkarte in den Kartenschieber (8) fließt Strom über alle Kontakte (9-11) dadurch wird wegen Kontakt (10) das Verbindungskabel zum Türöffner (12) vom npn Transistor (13) unterbrochen und es fließt Strom auf den npn Transistor (14) . . .<By inserting a sheet metal card into the card slide ( 8 ) current flows through all contacts ( 9-11 ). Because of contact ( 10 ) the connection cable to the door opener ( 12 ) is interrupted by the npn transistor ( 13 ) and current flows to the npn transistor ( 14 ). , ,

. . . dann wird dem Transistor (15) kein Strom zugeführt, dieser gibt dann die Stromzufuhr für die Verbindung auf das Selbsthalterelais (16) und den 12-Volt- Block (17) frei. , , , then no current is supplied to the transistor ( 15 ), this then releases the current supply for the connection to the self-holding relay ( 16 ) and the 12-volt block ( 17 ).

Das Selbsthalterelais (16) zieht an, dadurch wird die Sirene (18) und die Antennenschaltung (19) gibt Signale an den Satelliten ab, dieser leitet diese weiter zu der nächsten Polizeistation.The self-holding relay ( 16 ) picks up, the siren ( 18 ) and the antenna circuit ( 19 ) emits signals to the satellite, which forwards them to the next police station.
