I How to Use the Terminals of the ALARM/CONTROL Connector

These terminals are used for emergency recording, auto time adjustment (Auto Adjust Time), taking measures against power
outages (Shutdown Time), and when installing a buzzer, a lamp, or similar alarm device. They are also used to synchronize
with the sequential display changeover.
The terminal pin array and connections are shown below.
The connector used should be compatible with the pin con-
figuration.

Time of this unit is adjusted to the preset time
according to the signal input. This signal output is
then generated for the setting time of this unit.
Time of all other units is adjusted to the setting
time of this unit.
Sequence changeover is effected according to
the signal input. Signal output is generated at the
time of sequence changeover.
The state of alarm suspension is assumed
according to the signal input.
Start of outage processing according to the sig-
nal input.
