smoke detector
An electronic device that detects smoke in the air and, at a certain concentration, triggers a loud alarm to warn of a possible fire.
In jeder Wohnung ist die Installation von Rauchmeldern gesetzlich vorgeschrieben.
In every apartment, the installation of smoke detectors is required by law.
The word is made up of 'Rauch' (smoke) and 'Melder' (detector/reporter). A 'Melder' is a device that signals or reports something. So a 'Rauchmelder' is literally a device that reports smoke.
Als die Batterie leer war, fing der Rauchmelder an zu piepen.
When the battery was empty, the smoke detector started beeping.
When a smoke detector detects smoke, you say it 'löst aus' (is triggered) or 'geht los' (goes off). The sound it makes is often described with 'piepen' (to beep) or 'schrillen' (to shrill/ring loudly).
Mitten in der Nacht ging plötzlich der Rauchmelder los.
In the middle of the night, the smoke detector suddenly went off.
In connection with mounting, the verbs 'installieren' (to install) or 'anbringen' (to put up/attach) are used. You usually install or attach a smoke detector to the ceiling.
Wir müssen in der neuen Wohnung noch Rauchmelder anbringen.
We still need to put up smoke detectors in the new apartment.
