Choose which relay terminals to use. Using the NO relay terminal is recommended because an
alarm indication will be obtained also in case the Alarm Cable becomes disconnected. The BTS
External Alarm Interface (EAI) should then be programmed to expect a closed circuit and to indicate

the Alarm Cable.
If the EAI expects an open circuit, use instead the NC and COM wires. The circuit will then close in
the A

condition. Refer to the table below for the color coding of the Alarm Cable.
