Section 2 - Getting Started
What is a DXL Intercom Station?
In a MicroComm DXL system, an
Intercom Station
refers to a speaker/microphone combination from which
audio communications can be carried out. Associated with the Intercom Station are one or more switches that can
be used to generate call request, select programs or other possible functions.
How the DXL System Handles Alarms
The MicroComm DXL is an integrated system that handles a wide
variety of alarms, in addition to intercom call requests. To simplify
operation of the system, the DXL treats call requests and alarms in the
same basic fashion. (The only difference between the two is that, with
call requests, intercom functions are available.)
First we will discuss how the DXL handles alarms.
Normally, the Stations that communicate with your Master Station are
in the “idle” state.
When a Station initiates an alarm, the alarm is sounded at your Master
Station, and the system changes the state of that Intercom Station
from “idle” to “alarm”.
When an alarm is acknowledged, the system changes the status of the Station from “alarm” to “acknowledged”.
And when the alarm is canceled, the system changes the status of the Station from “acknowledged” back to “idle”.
The DXL keeps track of the status of all Stations and displays this information for you - as lists of Stations with
“alarm” and “acknowledged” status.
Now let’s look at call requests.
How the DXL Handles Call Requests
When a
call request
is initiated at an Intercom Station, the Master
Station alerts you (with a beep). The station that initiated the call
request is added to the Event Queue. Until the call request is
acknowledged, the Master Station will sound an
alarm reminder beep
at a regular interval.
When you acknowledge the call request:

a tone sounds at the Intercom Station to let the calling party
know that the call request has been acknowledged,

the DXL removes the Intercom Station from the Event Queue,
and

your Master Station is connected to the Intercom Station.
Once you are connected, you may speak to the calling party, or listen.
When you have completed your communications with the Intercom Station you may “end” the call.
