About the Alarm
Alarm notification using API
When alarm settings are set to send alarm information to DM-NC40 with API, the monitor mode DM-NC40 that
receives the notification works as follows: (For details on settings, see page 37)
1. If the source unit is registered in the telephone book, the number of source unit flashes on the number
display of the monitor unit.
2. If the monitor is connected to another unit, the connection is disconnected when the PLAY button is
pressed, and new connection to the source unit is made.
3. When monitor unit receives multiple alarms from many source units, and if STOP button is pressed
instead of PLAY button, each source unit numbers flash on the panel. If there are no more alarms, the
unit will return to the previous connection before the first alarm.
Memo
• Up to 10 alarm notifications can be handled as above.
• When connected with PLAY button, encode parameters in the telephone book of the monitor unit are used. If
there are multiple registrations having same IP addresses in the telephone book, smallest Edit No. is used. (In
observing mode, monitor unit obeys settings of camera side.)
• Alarm notifications from DM-NC40 units not registered in the TELEPHONE BOOK is ignored.
• Alarm notifications from current connecting DM-NC40 is ignored.
• If the acceptance is set to automatic (AUTO), monitor unit connects to the alarm source unit automatically
without pressing PLAY button.
• If the acceptance is disabled (OFF), alarm notifications is ignored. (Acceptance setting can be changed in
NETWORK SETUP screen.)
• When encode parameters of camera mode are changed by connection from monitor mode, image file recording
is stopped during the parameter change is in progress. Same settings to both camera mode and monitor mode
are recommended to avoid such problem.
• Alarm notification is ignored during IP address display at start.
