How to Use the Terminals of the ALARM/CONTROL Connector
These terminals are used for emergency recording, auto time adjustment, taking measures against power outages, and when
installing a buzzer, a lamp, or similar alarm device.
The terminal pin array and connections are shown below. The connector used should be compatible with the pin configuration.
Pin Configuration
The pin array is different from other disk recorders. Make sure that
the connection is correct referring to the following.
