    Arrow Federal PA300 Siren Help Needed for my old Mack CF Pumper

    I am a vol FF and restoring a '69 Mack CF. The PA300 012 NY that I have in it broke the other day and hoping to get some advice to fix it.
    I get a "fast yelp" on the Yelp and Wail settings. Being a NY model, it is silent in HI-LO as expected and the manual hold switch (the horn/siren 3 way switch on other models like model MSC) simply puts out a constant high pitch.

    Something fried but I am an old mechanic, not an electronics expect, so hoping to get some guidance on how to diagnose and fix it.

    Thanks in advance for the help.

    Easy fix.

    Take out the broke one and throw it in the trash.

    Replace with one that works.

    Management is making sure things are done right. Leadership is doing the right thing. The fire service needs alot more leaders and a lot less managers.

    As common as that unit was,it will probably be cheaper to replace it than fix it.These show up pretty regularly on E-bay.Could be either a board problem or an output transistor. The transistor is easy,the board;not so much. Good luck! T.C.

    Robert!! The Gentleman is talking about restoring an Antique. Not me, some other Antique. (I hadda make THAT Disclaimer before FWDBuff gets here. ) I can't direct him to a specific fix, but that reference to "Watch eBay" is a great idea.

    Speaking of FWD, Randy, Any ideas??

    True enough Chief, and all the more reason to replace the siren. PA300's were not arouund in 1969.

    If he is "truely" restoring it, he needs to find the kind of siren that is was originally equipped with. Watch for one of those on ebay!

    I do have an idea about how old you are; so old that you shoveled coal into a steamer! (sorry had to be done since you one-upsmanshipped me)

    Couple of ideas about sources of parts. I think though that TC is right, probably cheaper to just replace the box. But where to get a new (used) one????

    I can't help you with the siren problem, but I would love to see the pics of your restoration.

    I love the Mack CF chassis. Put an aerialscope on the chassis and I am a happy man.
