Abstract
- einem Gehäuse, das über geeignete Mittel an der Decke eines Raums anbringbar ist,
- einer Meßkammer zwischen einer unteren annähernd horizontalen Gehäusewand und einer im Abstand und parallel zur unteren Gehäusewand verlaufenden Trennwand (55), die einen optischen Meßpfad und seitliche Öffnungen für den Eintritt von Umgebungsluft aufweist,
- einer parallel und im Abstand zur und oberhalb der Trennwand angeordnete Schaltplatine, die neben einer elektronischen Schaltungsanordnung die optischen Elemente für den Meßpfad hält, deren Halterungen sich durch Öffnungen in der Trennwand erstrecken,
- einer vorzugsweise mittigen Öffnung in der Trennwand und
- einem oberhalb der Trennwand angeordneten Schallgeber, der über Leitungen mit der Platine verbunden ist.
