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.
Cancel
Alarm
Station Status
is "Idle"
Receive
Alarm
Normally, the Stations that communicate with your Master Station are
in the “idle” state.
Station Status
is "Acknowledged"
Station Status
is "Alarm"
When a Station initiates an alarm, the alarm is sounded at your Master
Station, and the system changes the state of that Intercom Station
Acknowledge
Alarm
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:
End
Call
Station Status
is "Idle"
Receive
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.
Page 5 MN-DXL-IMS-640-Pv1
Station Status
is "Acknowledged/Call"
Acknowledge
Call Request
Station Status
is "Alarm"
Page 12
IMS-640 VoIP Intercom Master Station Operating Instructions MicroComm DXL
After a fixed interval, if the call request is not acknowledged (or canceled), it will “time out” and a call request
time-out alarm will be annunciated at the Secondary Master Station. (The original call request remains queued at
the Master Station.)
Note: When the system is set up, the System Administrator will set the time allowed before a time-out
alarm is triggered by a failure to respond to the call request.
A Secondary Master Station is simply another Master Station designated to receive time out calls, fault reports as
a back up function.
All intercom activities (call requests, calls, cancels, etc.) are logged so that they can be printed and accessed for
review.
Intercom Stations
A typical Intercom Station consists of:
a call switch
a loudspeaker/microphone, which enables two-way
communication.
Intercom Stations may also take the form of telephone handsets, talkback
loudspeakers with call request buttons, etc. Whatever their configuration,
they include a means to place a call request and a means of two-way
communication. They may include call indicator lights to signal that call
requests have been placed or that calls have been acknowledged.
Typical Intercom Station
Initiating a Call Request
A call request is initiated by pressing the call request switch (lifting the telephone handset, etc.) at the Intercom
Station.
A call request will not be able to be initiated from an Intercom Station if:
the Station is disabled, or
the Station has initiated a call request that has not yet been acknowledged.
Disabled Stations
If you disable an intercom or other station, it can no longer initiate a call request. However, you may call a
disabled Intercom Station.
At any time, you may enable a disabled Station, which puts it back into operation.
When you disable a Station, it is added to the Disabled List. When you enable a disabled Station, it is removed
from the Disabled List.
Intercom Calls
Your Master Station will be connected to the Intercom Station whenever:
MN-DXL-IMS-640-Pv1 Page 6
Page 13
IMS-640 VoIP Intercom Master Station Operating Instructions MicroComn DXL
you initiate a call to the Intercom Station, or
you acknowledge a call request. (In this case, the Master Station is automatically connected to the
Intercom Station.)
When you call an Intercom Station, a call announce tone sounds (this indicates to the party at the Intercom
Station that you are calling, or that you have acknowledged the call request).
Note: An Intercom Station cannot initiate a conversation with the Master Station. The Intercom Station
can only communicate with the Master Station when the Master Station calls the Intercom Station, or
acknowledges a call request from an Intercom Station.
Station Identification
When the system is initially set up the using the Administrator Software stations will be identified by an ID
number and name. The IMS-640 LCD screen will display both.
Station Priority
Each Station is assigned a call request priority in the Administrator Software. Call request priority determines the
order in which Stations that have initiated call requests are displayed on the Event Queue.
A new call request with a high priority will appear on the Event Queue ahead of previously received call requests
with lower priority.
IMS-640 VoIP Intercom Master Station
The IMS-640 Intercom Master Station is a
telephone style master station and includes:
a display,

Beeper
The Master Station contains a beeper. Various conditions will cause a beep:
new alarm beep
a single tone will sound when a new call request or other alarm is received
an error beep
a single tone will sound when you press a numerical key
reminder beep
a double beep will sound at a fixed interval (from 5 to 60 seconds) as long as all call requests have not
been acknowledged.
The reminder beep interval is set in the Administrator Software.
Note: If you are in a call, the reminder beep and new alarm beep will be disabled for the duration of your call.
Once your call is completed the reminder beep and new alarm beep will automatically be re-activated.
Loudspeaker and Microphone
A loudspeaker and microphone are included in the IMS-640. They are used for hands-free communication with
Intercom Stations and other Master Stations. When using the loudspeaker and microphone to communicate, the
communication is one way at any one time so each party must take turns speaking. The Master Station operates
with a Voice operated switch (VOX) and the communication path will switch automatically so that it routes the
signal from the person speaking to the person listening.

IMS-640 VoIP Intercom Master Station Operating Instructions MicroComn DXL
Handset
The handset can also be used to communicate with Intercom Stations or other Master Stations. When the handset
is lifted from its cradle, the loudspeaker and microphone are automatically disconnected.
Handset communications to Intercom Stations are one way as for loudspeaker and microphone communications.
When speaking to another Master Station using its handset, both parties can speak and listen at the same time as
for normal telephone communications.

Section 3 - Principles of Operation
Menu System
A compact Master Station requires a small display and a limited sized keyboard. To achieve this goal and still
provide the required functionality, the DXL IMS-640 uses four programmable keys (called function keys) and a
menu system that defines the function of the keys. The bottom two line of the display shows the different
functions. Each time you press a function key either the specified action will be carried out or the menu will
change allowing you to make further choices. The structure of menu system resembles an inverted tree, staring at
the top level the menu is called the “Idle menu”.
From the “Idle menu” if we press one of the function keys, for example
Call, we move down the tree to a lower level menu (similar to moving to
one of the tree branches).

Lists
The MicroComm DXL uses two types of lists to perform its functions:
Active Lists - these are lists that change as calls and alarms are placed, acknowledged and canceled. Active
lists help you know what is happening at your station at any time.
Directory Lists - these are lists that contain all the Master Stations, Intercom Stations, paging zones, and
visitor booths that your Master Station can communicated with. Directory lists let you find stations that you
need to communicate with or control.
The number of stations on the Active Lists will vary from time to time.
The length of the Directory Lists, on the other hand, is constant.
Unless they are doing the same job, your Master Station will probably have different Directory Lists than the
other Master Stations in the system.
The following describes the Active Lists:

Note: A maximum of three stations can be displayed at one time.
The current list sizes of the Event Queue, Acknowledged List and Disabled List. These values appear on the
right-hand side of the display in the top three rows. They are always displayed.
Remember that these lists vary in size from time to time. Even if the list size is zero, a value will still appear.
A set of functions that you can perform by pressing the function keys immediately beside the display.
Let's look at this information in more detail:
Alarm Code
The alarm code indicates the type of alarm that has been received:
Alarm Code Meaning
I Intercom Station Call Request
A Audio Level Alarm Call Request
t Call Request Time-out Alarm
d Disabled Station Alarm
M Master Station or Staff Call Request
F Fault Alarm

Page 25
IMS-640 VoIP Intercom Master Station Operating Instructions MicroComn DXL
T Tamper Alarm
Note: t and d alarms are displayed only at the Secondary Master Station.
ID Number and Name
All the stations in your facility are identified by ID Number and Name. The ID Number is a numeric value
(between 1 and 65,535) assigned to the given station. It has no special significance other than the fact that it is a
unique identification for that station only. The Name describes the Station in terms commonly used in your
facility. The Name may contain any characters, including numbers and punctuation and it may be up to 20
characters long. On the display Stations are identified by both ID Number and Name
List Order
Each list has its own default order. The default order is the order in which the DXL normally displays the Stations
on that list.
Event Queue
Stations are sorted according to call request priority. (The DXL Administrator Software is used to set the
priorities of the Intercom Stations.) If two or more Stations have equal priority, they will appear in the order
in which their call requests were received.
Acknowledged List
Stations are sorted in the order in which they were acknowledged.
Disabled List
The Disabled List display stations in order of Station ID Numbers.
Directory Lists
The order will be by ID Number.
List Sizes
The three numbers on the right hand side of
the display indicate the current number of
Stations on each of the three variable-length
lists:
2001
TOP -- Event Queue
MIDDLE -- Acknowledged List
BOTTOM -- Disabled List
Remember that these values will vary. At
any one time, the list size may be zero or
some number up to the total number of
stations

A Shortcut to Help With Long Lists
For lists that are sorted by ID Number you can sometimes shorten the list
of displayed stations by typing in the first number of the station i.e. by
typing in a “2” only the stations with ID numbers that start with “2” will
be displayed.
Now you can use the Up-Arrow
and Down-Arrow keys to scroll
through the shortened list to make your final selection.
Let’s say the ID Number of the station you want starts with a “2”. Press
“2” and only those stations beginning with ID Numbers beginning with
“2” will be displayed - this would include “2”, “20 …29”, “200 …299”,
“2000”, “2001” … “2999”, etc.
At any point you can stop and use the Up-Arrow and Down-Arrow keys

If you now type in a “0” only those stations with ID numbers that start

Making a Call to a Station
This procedure is used for making a call to an Intercom Station.
You may call an Intercom Station from any list on which it appears.
Reminder: When you acknowledge a call request from the Event Queue, you will automatically be
connected to the Intercom Station.
Caution: If you call a station from the Station List or from the Disabled List and that station is also listed
on the Event Queue, the system will treat your call as though you had acknowledged the call request.
In this example, we will make a call from the Station List.
To access the Station List press Call
followed by Station. Now select the Station
you want from the Station List.

Background Monitoring
Background monitoring allows a master station to continuously monitor a
station, stations or a pre-defined group of stations. Each Station in the
group is monitored for a preset time. The monitoring continues in a cyclic
fashion.
From the “Idle menu” pressing the Monitor function key brings up a new
menu. Pressing the Background function key on this new menu brings up
the following display with three function key options.
The monitoring rate specifies how long an individual station will be
monitored before cycling to the next station in the monitoring list. If we
press the Monitoring Rate function key the following menu will appear.
The monitor rate can now be adjusted using the up () and down ()
arrow keys. The value can be adjusted from 1-3600 (seconds), i.e. from 1
second to 1 hour. This is the amount of time that the Master Station will
stay at one particular station during monitoring. If the monitoring rate is
decreased to 0 the monitoring will be DISABLED. This allows you to turn
off the background monitoring without altering the monitoring list. Once
you have set the monitoring rate you can either press the Accept function
key or the Cancel function key to return to the previous rate. In either
case you will return to the previous menu
