Circuit Notes
Any number of normally-open switches may be used. Fit the mercury switches so that they close when the steering is moved or when the bike is lifted off its side-stand or pushed forward off its centre-stand. Use micro-switches to protect removable panels and the lids of panniers etc. When one of the trigger-switches is closed - the relay will energize and the siren will sound.

You can choose what happens next. If you build the circuit as shown,
the siren will continue to sound until you turn it off - or until the
battery is exhausted. But, if you leave out D3 - the siren will stop
sounding immediately the trigger-switch is re-opened.
While you're within earshot of your machine - the former
configuration is best. You can always turn off the alarm yourself. But
if you are going to be away from your bike for any length of time - and
you don't want to cause a nuisance - then the latter configuration is
probably more suitable. If you include a SPST switch in series with D3 -
you can select the behaviour that best suits the circumstances at any
given time.
