1. External Alarms Connection:

There are two types of environment monitoring configurations for the BTS3012:

A DEMU is built in the common sub rack and connects to the external

sensor through a cabinet top cable.

Environment alarm box (EAC-2), communicates with the DTMU through

CBUS3.

Here in V7 project, we use the first type to configure the external alarm.

When installing the DEMU of the BTS3012, we need to configure a DDF box for

the DEMU. The configuration procedure is as shown below figure.

Figure 11-1 Installing a DDF box for the built-in DEMU

All alarm signals are collected from rectifier cabinet, fire alarm control panel,

generator system, air-condition, HVAC control panel and door switch sensor, ect.

And firstly all this signals will be connected to the DDF as a group. The picture below

shows the blocks used inside HUAWEI DDF cabinet.
