cap on buzzer
(OP)
I've got a simple control box for a gate arm, adn there's an alarm buzzer. It's a 24v standard issue black, maybe 2" diameter 100dB or so buzzer. Question is, why is there a 470mF cap across it?

RE: cap on buzzer
Is it the size of a half gallon of milk? If not please look closer and see if it is 470uF or .47uF or .047uF or 470pF. These would make way more sense.

However, if the 'buzzer' is really a piezo-type, then a 470uF would cause it to beep a little longer when pulsed. A quick 'chirp' would turn into a very short beep.
