• If there is a sensor input at the remote site (transmit-
ter), then automatic transmission is performed toward
the preset distant party. The destination can be
changed according to the day of the week and time
zones. It can be preset in three types of time zone
tables.
• On account of the setting for the image storage func-
tion, no transmission may be started until image stor-
age is finished.
• After the lapse of preset time after automatic transmis-
sion, the line is automatically disconnected by the
basic function.
However, if the
ALM ACK
button or the
ALM MEMO-
RY
button is pressed on the receiver side, then the
line is not disconnected and communication is main-
tained.
• The sensor input has 8 systems. Each can be set for
the automatic transmission destination. The automatic
transmission destination for a sensor is in higher pref-
erence corresponding to the preceding sensor input.
An alarm input entering later cannot be accepted until
the preceding communication has been finished.
For viewpoint interlocked functions, however, opera-
tion is possible at any time.
• If the connection cannot be accomplished on account
of alarms during automatic transmission or the desti-
nation being busy, then transmission is addressed to
the second destination and third destination.
• If transmission to the third destination fails, then the
transmission sequence is repeated (up to twice) about
one minute after for the first destination, second desti-
nation, and third destination. If the connection is not
successful after this, then the alarm transmission is
canceled. However, this transmission sequence is fur-
ther repeated if the level type sensor is ON.
• During the time period after completion of communica-
tion till the attainment of standby condition, no alarm
transmission is carried out. Records of alarms are
stored in the alarm log.

Edge alarm
Minimum time
100 ms or more
An input of less than 100 ms cannot be
detected. (Signal input of less than 100 ms
may be a cause of misoperation.)
Each time the same
alarm is detected, the
auto-disconnect timer is
reset.
If multiple alarms enter
within 100 ms, an alarm
with a smaller input
number is of higher
preference. (For this
example, an alarm input
at Sensor Input 3 may be
disregarded.)
