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 terminal plug 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}.
