VOX Support

When in VOX mode the SCW9047 automatically switch between the phone line and internal mic/speakers being active depending on which one is loudest. Push to Talk overrides VOX – this is performed by switching into a talk mode at the monitoring station .

Hang-up Auto-detection

The SCW9047 automatically disconnects if the central station receiver disconnects before the operator picks up the line. The SCW9047 will consider five seconds of continuous dial tone, or busy tone to be a disconnect condition.

Bell/Buzzer Silent During 2-Way Audio

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.
