ebike alarm with timer ne 555
works well with vibration sensor :-)
and 120db piezo at the output of the timer
is a piezo horn or siren 12v  with its own electronics

I use a 433Mhz remote control.
When alarm is triggered, it lasts about 12 seconds and stops again. 
The circuit is then armed again !

Thought it might help. EC does not have a piezo. So we need to use its eqiuvalent cct. Instead, which does work...
