[K4nape]

Thank you so much @Udo_Hartmann @opus @PtrO

This code work finally to.

@K4nape

var int counter = 0
rule "counter"
when
Item alarm received update
then
If (alarm.state == 3 && counter <= 2) {
    counter = counter +1
}
else if (counter == 2) {
test.sendCommand(ON)
createTimer(now.plusSeconds(15))
[|
test.sendCommand(OFF)
counter = 0
]
}
end

but i chose more optimized, thanks for @Udo_Hartmann

@Udo_Hartmann

// define global vars at the top of the rules file!
var int counter = 0


rule "counter"
when
    Item alarm received update
then
    if(!(alarm.state instanceof Number)) {                       // Type correct?
        logWarn("alarm","alarm not of type Number!",alarm.state) // No
        return;                                                  // stop rule
    }
    if((alarm.state as Number).intValue == 3 && counter <= 2)    // alarm, so 
        counter = counter + 1                                    // count up
    if(counter == 2) {                                           // second alarm?
        test.sendCommand(ON)                                     // switch test ON
        createTimer(now.plusSeconds(15), [ |                     // create a timer for 15 Seconds with code
            test.sendCommand(OFF)                                // switch test OFF
            counter = 0                                          // and reset counter
        ])
    }
end

Now i have fire alarm notification.
