■ 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 con-
nector used should be compatible with the pin configuration.
Pin array
The pin array is different from other disk recorders. Make sure that
the connection is correct referring to the following.
