All tones require a minimum of 180ms of ringing voltage (or contact closure) to trigger. Once triggered, the electronic war-
ble will run continuously until ringing stops (or contacts open). All other tones (double gong, quadruple chime, 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.
