All tones require a minimum of 180ms of ringing voltage (or contact closure) to trigger. Once triggered, the electronic
warble and electronic bell will run continuously until ringing stops (or contacts open). All other tones (double gong,
quadruple chime, and doorbell) will run through their full sequence once and will not cycle again until the ringing
stops (or contact opens) for at least 50ms and a second ring signal (or contact closure) triggers them again.
