Ok, I gave up on the string method... the three stooges came to mind.
I did buy a new systems from Amazon / Silent call. It's basically a watch I wear at night and it receives a message when a sensor
detects sound (I set the threshold). The watch vibrates and wakes me.
So, this system is battery
operated and small. I can set the sensor
next to the GPS
and when and IF an alarm
sounds, I'll be woken via vibration. This would apply to other LOUD sounds as well.
Dual purpose is that I'll use it at home to alert me if a smoke detector activates or other LOUD events
. I can also buy separate transmitters for phone
, C02, door bell, etc, etc.
but I think it will do the trick.
