Electrical chimes require more electricity than mechanical chime to operate. So we implemented a wait time to prevent a possible discharge (exhaust) of the internal doorbell battery.
Note: The internal doorbell battery is not for wireless use. It is meant to keep the electricity flowing to the doorbell for when it is shorted (pressed). When the bell is pressed, all the electricity flow will be directed to the chime, therefore there will be no electricity flowing to the doorbell for a short period of time.
