■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-!3q nector used should be compatible with the pin configuration.
