This section describes the alarms related to the BTS3606E equipment room environment and 
their handing methods.

Room environment alarms are collected by an environment alarm chest (EAC) connected 
with the BTS3606E. Such alarms include the fire alarm, smoke alarm, access control alarm, 
water alarm, temperature alarm, humidity alarm, and air-conditioner alarm.

The process for handling an environment alarm is as follows: 
Step 1  Upon receiving an environment alarm, the OMU starts the related external devices, such as 
air-conditioners, fire extinguishers, smoke removers, and dehumidifiers. 
Step 2  The OMU reports alarm messages to the OMC. 
Step 3  The OMC displays the alarm on terminals so that maintenance engineers can take actions to 
clear the alarms.
