Important:
• Use only the dedicated connection cable provided with the extension unit when connecting the recorder and the extension
unit.
• Fix the connection cable rmly using the cable clamp included in the extension unit. When the cable is not connected rmly
or when it is disconnected, the system may become unstable or recording may fail.
Refer to the operating instructions of the extension unit for details on how to t the cable clamp.
• Do not wind the cable in a coil.

How to use the terminals of the ALARM/CONTROL
The ALARM/CONTROL connectors on the back is used when connecting an external device such as a sensor that outputs alarm
signals or when installing an external alarm device such as a buzzer or a lamp outside.
Insert the unarmored cable into the included terminal plug (12 pin) and then mount it on the ALARM/CONTROL connector on the
back.
* The cable should be a single or twisted wire with AWG 26~16 and an exposed length of 9 mm {11/32 inches}.
