Listen-In Mode:
The SD2 has a listen-in mode, which switches an internal microphone to
the telephone line so that you can hear activity at the protected site.
The contact can activate the listen-in mode at the time of receiving a voice
message or by calling into the SD2 and using the Remote Access feature.
Talkback Mode:
The SD2 has a talkback mode, which switches the internal loudspeaker to
the telephone line so that you can talk to the protected site. The contact
can activate the talkback mode at the time of receiving a voice message or
by calling into the SD2 and using the Remote Access feature.
Message:
The SD2 has a message feature, which allows you to record up to 15
seconds of audio. A user can record a message locally, at the unit, or
remotely, using a touch-tone telephone. After recording a new message
the unit will indicate it on the display and optionally gives a beep. You can
also program the message feature to record when a trigger input is
activated.
Remote Access:
If you enable this feature you can access the SD2 remotely by dialling into
the unit with a touch-tone telephone. Once connected you can turn on and
off the two outputs, activate the listen-in/talkback mode, listen to the
message, or record a new message.
