Bosch 3000 siren wiring

[psi]

hi I need a bit of advise. I am installing a bosch 3000 alarm and not sure on how to wire the horn strobe out door box. The horn/siren has a red and a black and two yellow wires. I have been using this Dia to work it out but it dosnt show the red and black wire coming from the siren. Would they go to the + - strobe connections as well?



The only other thing im not 100% on is wiring in two key pads , i have just wired them both into the same connections on the board as in the dia. is this ok?
Any help would be greately appreciated.

this is similar to the siren that is in the box , i cant find any info on the yellow wires, should they be wired up with the tamper wires?

It's probably a dual siren / horn.
So if connecting as per dia use yellow wires as bosch panel is a horn output.
Red and Black is if panel had voltage output for siren
