. Maybe 5% of the volume compared to when I attached elsewhere.
Measuring the current
with a DC clamp meter _could_ reveal a high current
, but how high is too high? Doesn't it mention the max current in the manual? A better and easier/cheaper way (if you don't have a DC clamp meter) is to measure the voltage on the buzzer while it's buzzing. It should not drop more then 0.5V.
Secondly, what happens if the alarm
goes off but you're not on board?
