ALARM Connectors provide Customer Defined Alarm Inputs and

Outputs. The customer can connect BTS Site Alarm Input Sensors and

Output Devices to the BTS, thus providing Alarm Reporting from active

sensors as well as controlling Output Devices.

The SC 4812T Lite is capable of concurrently monitoring 35 Iinput

Signals. These Input Signals are divided between two Alarm Connectors

marked ‘ALARM A’ and ‘ALARM B’ located at the top of the frame.

Refer to Figure 3-44.
