Door Status Alarm
The door status alarm is an environment alarm generated when the door of the equipment room
or the door of the cabinet is opened. This is a major alarm.
Burglar Alarm
The burglar alarm is generated when the infrared alarm or door status alarm occurs. This is a
critical alarm.

4.6.2 Checking the Environment Monitoring Alarms on the LMT

This describes how to check the environment monitoring alarms. Checking the environment
monitoring alarms is implemented through simulating the environment factors that may generate
alarms, thus checking whether the physical connections of the BTS can report and clear the
alarms. Note that the BTS technical support engineers should assist in checking the Boolean
environment monitoring alarm.
