    I want to make an alarm circuit for pressure switches.
    It may be 5 channels. I will use 5 pressure switches (Normally Open).
    alarm circuit will have acoustic alarm and light leds.
    alarm circuit will have two buttons Reset and Test.
    if any pressure switches goes short circuit, acoustic alarm and led will shed.
    When user press reset button acoustic alarm will be off for 3 or 5 minutes but light led will still work.
    Test button cancel reset button.
    when the pressure switch return to open status alarm return to normal without press acknowledge button.

    Should I user micro controller or not?
    Can any one give me a circuit?
