This is a Telefunken L801 or L801a. All versions have a driver for ELA, they were never used for signal horn, only ELA.
If you search for Telefunken L801 you will find more detailed information!
that was my toughts too.
Thanks for the deatiled answer!
90% that is only for P.A. The Speaker looks to small for twin use.
Normally these Speakers could only be used up to 5. max. 10W, that is to low for a siren.
The Siren sound of this Magirus is only used by compressed air through the Martin trumpets. These old fire trucks normally used only one siren, two sirens were the exception.
the switch panel shown on the pictures below is on our local FD's Magirus fire engine.
It is clear that once it was connected to the BOS radio system, and also to the big red speaker on the top.
Could it also make a siren sound or this is only for P.A.?
Thank you for your help guys.
