    Default Alarm Piezo

    I have installed a new bosch alarm every thing is working well
    except for the piezo screamer it is connected from N/O to ground
    I tested it on a 12 v battery and worked ok
    The wiring diagram has wired pir's of it but i am using wireless
    i don't think this is the problem
    please view wiring diagram http://www.boschsecurity.com.mx/_arc...ef_0506_en.pdf
    Can i use another circuit like the siren?

    Seacrest,
    Check that link (No 7 on the drawing) is installed between 12V and COMM. This is what directs the internal 12V supply to the COMM terminal and then to the N/O when activated.
    Those were the droids I was looking for.
