Abstract

The fire alarm has an externally visible light indicator with one or more wreath-shaped light surfaces (7) on the part of the alarm surface that can be seen. The light surfaces radiate in different directions. The light indicator can contain one or more light conductors that carry light from the light source to the light surfaces.

Description

Stand der TechnikState of the art

Die Erfindung geht von der Gattung aus, wie im unabhängigen Anspruch 1 angegeben und bezieht sich bevorzugt auf einen Brandmelder.
Bei den heutigen Brandmeldern wird der Alarmzustand (der eingetreten ist, wenn der Brandmelder einen Brand erkannt und an seine Zentrale gemeldet hat) mittels einer roten Leuchtdiode, die an der Außenhaut des Melders, also sichtbar angeordnet ist, punktförmig dargestellt.The invention is based on the type as specified in independent claim 1 and preferably relates to a fire detector.
With today's fire detectors, the alarm status (which has occurred when the fire detector has detected a fire and reported it to its control center) is shown in a dot-like manner by means of a red light-emitting diode which is arranged on the outer skin of the detector.

Brandmelder bestehen mechanisch im wesentlichen aus zwei Teilen: einem Sockel und einem Melderkopf. Der Sockel wird an eine Decke geschraubt und verkabelt, der Melderkopf wird mit dem Sockel mittels eines Bajonettverschlusses kontaktiert und verriegelt. Die Leuchtdiode sitzt am Melderkopf. Dabei gibt es zwei Varianten:Mechanically, fire detectors essentially consist of two Share: a base and a detector head. The base will screwed to a ceiling and wired, the detector head is attached to the base using a bayonet catch contacted and locked. The LED sits on Detector head. There are two variants:

Bei der älteren Variante (Netz-Optischer Melder NOM 100 von TELENORMA) hat der Melder eine parallel zur Decke verlaufende Abschlußebene, die aus jeder Richtung zu sehen ist. In der Nähe des Randes dieser Ebene befindet sich eine aus allen Richtungen sichtbare LED als Leuchtanzeiger.In the older variant (network optical detector NOM 100 from TELENORMA) the detector has a parallel to the ceiling trending final level that can be seen from any direction is. Located near the edge of this level an LED visible from all directions as Light indicator.

Bei der neueren Version (Optischer Rauchmelder GOM 120 von Bosch Telecom GmbH) hat der Melder eine tiefliegende, runde Abschlußfläche, die von einer höherliegenden, das heißt näher an der Decke liegenden, die Außenhaut des Melders mitbildenden, konischen Ringfläche umgeben ist; zwischen dieser Ringfläche und der Abschlußfläche befinden sich Öffnungen, in die der zu meldende Rauch eintreten kann. Als Leuchtanzeiger ist auf der Ringfläche eine LED vorgesehen, die aber nicht aus allen Richtungen sichtbar ist, da sie bei bestimmten Blickrichtungen von der Aschlußfläche verdeckt ist.
Daraus ergibt sich das Problem, daß der Sockel bereits so lagerichtig an der Decke montiert werden muß, daß die LED nach dem Aufsetzen des Melderkopfes in Richtung Raumeingang zeigt. Da die Installationsarbeit des Sockels teilweise von Subunternehmern ausgeführt wird und diese oft nicht auf die Montagerichtung achten, gibt es für den Monteur, der letstlich nur noch den Melderkopf aufsetzen soll, erheblichen Mehraufwand, wenn die Verdrahtung des Sockels wieder gelöst, der Sockel abgenommen, neue Befestigungslöcher lagerichtig gebohrt und der Sockel neu montiert und wieder verdrahtet werden muß.In the newer version (optical smoke detector GOM 120 from Bosch Telecom GmbH), the detector has a low-lying, round end surface, which is surrounded by a higher, that is, closer to the ceiling, conical ring surface forming the outer skin of the detector; there are openings between this ring surface and the end surface into which the smoke to be reported can enter. An LED is provided as a light indicator on the ring surface, but is not visible from all directions, since it is covered by the outer surface in certain viewing directions.
This results in the problem that the base must be mounted on the ceiling in such a correct position that the LED points towards the room entrance after the detector head has been attached. Since the installation work of the base is partly carried out by subcontractors and they often do not pay attention to the installation direction, there is considerable additional effort for the fitter, who is ultimately only supposed to put on the detector head, if the wiring of the base is removed again, the base removed, new ones Mounting holes drilled in the correct position and the base must be re-assembled and re-wired.

Vorteile der ErfindungAdvantages of the invention

Der Anmeldungsgegenstand mit den Merkmalen des Anspruches 1 hat folgenden Vorteil:
Dadurch daß bei dem neuen Melder, insbesondere Brandmelder, das zur Leuchtanzeige dienende Licht an kranzförmig um den Melder herum angeordneten Stellen der Außenhaut austreten kann, ist der Alarmzustand des Melders sicher erkennbar unabhängig von der Montagerichtung des Sockels.The subject of the application with the features of claim 1 has the following advantage:
Characterized in that with the new detector, in particular fire detector, the light serving for the indicator light can emerge from the outer skin at points arranged around the detector, the alarm state of the detector is reliably recognizable regardless of the mounting direction of the base.

Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben, deren Merkmale auch, soweit sinnvoll, miteinander kombiniert werden können.Advantageous further developments are in the dependent Claims specified, the characteristics of which, to the extent useful, can be combined with each other.
