Ok so long story short replaced clutch today, disconnected and reconnected battery nw alarm is working but not sounding. Used to beep one time for disarmed an 4 times for disarmed, indicators flashing but no sound.
Can't be sure but maybe the battery back up battery has failed in the siren? :confused
Wahoo, :roflSpot on. Sometimes they recover once the battery is connected, sometimes they don't and you'll have to replace the siren or batteries depending on type.
