    Hi Goodfolks
    I am looking for a multiinput circuit ( 4 input )
    I wish to construct a circuit that I can use to wire up 4 seperate inputs that will activate a sounder in the event of an input being latched.
    Each of the 4 inputs is to be wired to 4 seperate boilerhouses if any of the boilerhouses go in to alarm mode I want the sounder to sound and a Led to illuminate to highlight the boilerhose where the alarm has been activated.
    I woud appreciate if I could be pointed in the right direction.
    many thanks
