Abstract
The alarm installation to determine when an intruder breaks into or out of a building comprises one or more security screens of hollow rods containing electrical wires which are connected to a central control desk. The latter has circuitry fed by two batteries and an electromagnet. If the current to the electromagnet is interrupted because of a break in the screen wires, an arm is pressed by spring action against a switch. As a result, a bell rings and a light lights up. The two batteries are preferably internally fitted and secured so that it would be difficult to put the apparatus out of order.
Description
Vorliegende Erfindung bezieht sich auf eine Alarmanlage zur sofortigen Feststellung eines Ein- oder Ausbruchs in einem mit dieser Anlage gesicherten Gebäude durch eine einzige Person.
Beim Erfindungsgegenstand gemäss dem Patentanspruch des Hauptpatents handelt es sich um eine Alarmanlage zur Feststellung eines Ein- oder Ausbruchs in einem Gebäude mit mindestens einem Sicherheitsgitter und einem zentralen Kommandopult, welches Sicherheitsgitter aus hohlen Stäben besteht, in deren Hohlräumen elektrische Drähte angeordnet sind, die mit dem zentralen Kommandopult verbunden sind.
Ein Ausführungsbeispiel der vorliegenden Erfindung wird anhand einer Zeichnung näher erläutert.
Das Kommandopult weist eine Schaltungsanordnung mit zwei Batterien 9, 10, einen Elektromagneten 3 und einen beweglichem Arm mit einer Feder 5 auf. Das Elektromagnet ist mit der einen Batterie über die in den hohlen Stäben der Gitter befindlichen Drähte verbunden. Wird der Strom für den Elektromagneten unterbrochen, so drückt der Arm 4 wegen der Feder 5 auf einen Schalter 6, der den Alarm auslöst, wobei eine Glocke 6 ertönt und das Licht eingeschaltet wird. Damit die Anlage erschwert ausser Betrieb gesetzt werden kann, weist sie eine eigene Speisung mit zwei Batterien auf.
PATENTANSPRUCH
Alarmanlage nach Patentanspruch des Hauptpatentes dadurch gekennzeichnet, dass das Kommandopult eine Schaltungsanordnung aufweist, die derart ausgebildet ist, dass, wenn die Drähte im Gitter (2) unterbrochen werden, ein Elektromagnet (3) ausser Betrieb gesetzt wird und so ein beweg- licher Arm (4) durch eine Feder (5) auf einen Schalter (6) drückt, so dass eine Glocke (7) ertönt und Licht (8) aufleuchtet.
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
The present invention relates to an alarm system for the immediate detection of a break-in or break-out in a building secured with this system by a single person.
The subject of the invention according to the claim of the main patent is an alarm system for detecting a break-in or break-out in a building with at least one security grille and a central command desk, which security grille consists of hollow rods, in the cavities of which electrical wires are arranged that are connected to the central control panel are connected.
An embodiment of the present invention is explained in more detail with reference to a drawing.
The control panel has a circuit arrangement with two batteries 9, 10, an electromagnet 3 and a movable arm with a spring 5. The electromagnet is connected to one battery via the wires in the hollow bars of the grid. If the current for the electromagnet is interrupted, the arm 4 presses a switch 6 because of the spring 5, which triggers the alarm, a bell 6 sounds and the light is switched on. So that the system can be put out of operation with difficulty, it has its own power supply with two batteries.
PATENT CLAIM
Alarm system according to patent claim of the main patent, characterized in that the control panel has a circuit arrangement which is designed in such a way that when the wires in the grid (2) are interrupted, an electromagnet (3) is put out of operation and a movable arm ( 4) presses a switch (6) with a spring (5), so that a bell (7) sounds and light (8) lights up.
** WARNING ** End of DESC field could overlap beginning of CLMS **.
