when the pir is tripped it has a output for 4sec. (adjustable)

when the pir trips I need

1 output to turn on 4 sec. (adjustable) after the pir trips and stay on for 4sec. (adjustable).then off.
if the pir trips again dearing this cycle. it has no effect.

I don't know exactly what you are using to do this/what language you are using/etc, but the basic logic for this would look something like this:

Loop forever
    Check if pir tripped
        If it was, then
            Turn Output on and wait 20sec
            Turn Output on and wait 4sec
        End of tripped situation
    End check
End of loop

The 20 and 4 could be variables which are settable in some way.

That help?

==EDIT==
Looks like this is in C, so, slightly more detail:

#define TRIPPED 1 // Whatever the "tripped" setting for the pir reads in the program

while(1)
{
    if(pir == TRIPPED)
    {
         // Turn on outputs and wait approriate times.
         // I'm not sure how'd you do this using your specific stuff.
    }
}
