When the panel has an audible alarm, the bell can be programmed to remain active until the 2-Way Audio session starts and then the bell will
be silent (Section [600], option 7 off) to allow the user to hear the operator. All buzzer activity, except keypresses, will be silent when 2-way
audio is active. If the panel has not been disarmed at the termination of the 2-Way Audio session, the bell will restart for the timeout dura-
tion. Door chime is disabled during a 2-way Audio session. Any activity that normally sounds door chime will occur and the door chime
will not sound.
