Abstract

Eine Rauch- oder Brandmeldevorrichtung (1) hat eine Mehrzahl von Rauch- oder Brandmeldern (3), eine Überwachungseinrichtung (5) und ein Bussystem (9). Das Bussystem (9) verbindet die Rauch- oder Brandmelder (3) mittels flammwidriger elektrischer Leitungen (11) zur Angabe des alarmgebenden Rauch- oder Brandmelders (3) mit der Überwachungseinrichtung (5). Diese Vorrichtung ermöglicht eine schnelle, sichere und ortsgenaue Rauch- und Brandmeldung und eignet sich insbesondere für öffentliche Gebäude wie Bahnhöfe, Flughäfen, Kaufhäuser und ähnliche (Fig.).

Figure 00000001
A smoke or fire detection device (1) has a plurality of smoke or fire detectors (3), a monitoring device (5) and a bus system (9). The bus system (9) connects the smoke or fire detectors (3) to the monitoring device (5) by means of flame-retardant electrical lines (11) to indicate the smoke or fire detector (3) giving the alarm. This device enables a quick, safe and location-specific smoke and fire detection and is particularly suitable for public buildings such as train stations, airports, department stores and the like (Fig.).
