Alarm Recording (Emergency Recording)
When an emergency occurs at the monitoring site during prolonged monitoring and recording, the alarm function
is automatically triggered, and alarm recording is performed.
Principle of Alarm Recording Connecting the Alarm Input
Connector
Alarm recording starts when the alarm switch is set
on. When the alarm reset switch is set ON after
recording has started, alarm recording is released
and operation is returned to the original time lapse
recording mode.
Alarm recording can be released by pressing the
STOP button during alarm recording.
However, it cannot be released even by pressing the
STOP button if the MENU/REC LOCK switch is at
REC LOCK or INT is lit on the display.
Alarm recording can be automatically reset without
supplying the alarm reset input signal.
The reset time can be set for 30 sec., 1.0, 2.0, 3.0,
5.0 or 10 minutes.
Another option is alarm recording only while the alarm
input signal is supplied.
Alarm recording is also possible as far as the end
of the tape.
