BASIC OPERATION/USE FROM THE COMMAND CENTER
1. Answering a station call
a. Answering a call is very similar to a standard telephone with a speakerphone and
handset options.
i. When the Command Center is ringing, you have the option to pick up the
handset and talk to the party.
1. If you would like to switch to speakerphone, press the SPEAKER
ON/OFF button and place the handset back on the receiver.
ii. You can leave the handset on the receiver and press the SPEAKER ON/OFF
button as well to answer the phone on speakerphone.
1. If you have answered using speakerphone button and want to use
handset, simply lift handset and continue conversation.
b. If the call is from an S3 Communicator, you will need to press 1 to talk to the party
or 2 to listen to the site ID message if the phone is not set to immediate two-way
calling.
2. Calling a station
a. There are multiple ways to call a station from the Command Center:
i. Using SELECT while handset is off hook.
1. Scroll ^ (UP) or v (DOWN) until you have highlighted the desired
extension.
2. Press SELECT on the highlighted extension and wait for an answer.
3. If you would like to communicate on speakerphone, press the
SPEAKER ON/OFF button and then place the handset on the
receiver.
ii. Using SELECT while handset is on the hook.
1. Scroll ^ (UP) or v (DOWN) until you have highlighted the desired
extension.
2. Press SELECT on the highlighted extension and wait for an answer.
3. Call will automatically be on speakerphone.
4. If you desire to use handset just lift it off the receiver and continue
conversation.
3. Ending a station call
a. How you end the call depends on whether the call is on speakerphone or through
the handset.
i. If you are communicating through the handset, you simply place the
handset back on the receiver.

9
ii. If you are communicating through the speakerphone (handset will be on
receiver) then you will need to press SPEAKER ON/OFF which will
disconnect the call.
iii. If you are unsure, pressing the END ALL CALLS button will disconnect all
active calls. This is explained further in the section titled “Ending call with
multiple stations”.
4. Holding a station call
a. Due to code compliance, the process of placing a call on hold may be different
from what you are accustomed to with a call waiting-enabled device. The
operation is embedded in the system to ensure callers will not be unanswered.
i. If you are connected to 1 caller with the Command Center, you will only be
able to place that caller on hold if the phone is on speakerphone.
ii. When another caller is calling in, the HOLD button will become active on
the right side of the display.
iii. Press the HOLD button and 2-way communication will automatically be
enabled with that second caller.
iv. If another call is ringing through, you can press HOLD again and be
connected to that call.
v. See “Answering a call with a call on hold” section for more info on holding
calls.
5. Answering a station call with a call on hold
a. Answering a call while a call is on hold is as easy as pressing HOLD and the next
call in the queue will be answered.
b. You are not able to select which car you talk to when there are multiple calls. The
priority is dictated by the caller that called in first and whether the call has already
been answered. This is executed internally by the Command Center.
c. See “Holding a station call” for additional information.
6. Joining multiple station calls
a. Joining a call or calls is a feature of the Command Center and can be accomplished
by pressing JOIN on the left side of the display for calls that are in progress. This
function does not join two calls together, but rather joins in on a call already in
progress.
i. To join a call, 1 or more phones connected to the Command Center have
to be on an active call.
1. You will be able to see that they are on a call by looking at the
display (the line on a call will be yellow with a “1” on the far right
indicating line is in use).

10
2. Press JOIN to connect the Command Center to the call.
3. You will now be able to communicate with everyone that is active
on this call.
4. You may disconnect from this conversation at any time by hanging
up the Command Center. The calls you joined will stay active until
they have disconnected themselves, or you press the END ALL
CALLS button.
7. Calling multiple stations (paging)
a. Calling multiple stations is accomplished by pressing the PAGE ON/OFF button.
i. The Command Center will ring any phone that is connected to it.
1. This is a one way call only and is for the Command Center to make
announcements.
2. Command center will connect S3 Communicator phones
automatically. Other phones on the line may have to be manually
picked up.
a. S3 Communicator phones set up for line sharing will not
answer a page due to the added menu option required to
reach the phone.
3. The page function will remain “on” until you press END ALL CALLS
to disconnect from all lines that were affected by the page.
a. While page is “on”, placing the handset on the receiver or
pressing SPEAKER ON/OFF will not disconnect the phone
as it typically would in a call. Switch to speakerphone by
placing the handset on the receiver, and switch back to
handset mode by lifting the handset.
8. Ending call with multiple stations
a. To end a call on multiple stations, the easiest and fastest way is to press the END
ALL CALLS button. This of course depends on whether you want disconnect from
one or all of those calls, because pressing that button will end ALL calls.
b. If you just wish to disconnect from one call at a time, then you may do so by
hanging up the phone on a call, which will bring the next call up in the queue to
be answered. This call can be ended by hanging up also and so on down the line
until they have all been ended.
i. You cannot hang up one by one if page was initiated. In this case, you must
END ALL CALLS.

11
9. Calling outside line
a. The Command Center can connect to an outside line if a valid external line is
present. There are two ways to accomplish this:
i. Scroll ^ (UP) or v (DOWN) to highlight the external line and press SELECT.
When you hear the dial tone, you can dial an external number.
ii. Another (and the most common) way is to press SPEAKER ON/OFF or to lift
the handset off the receiver. When you hear a dial tone, press 99 to get an
outside line followed by the number you wish to call.
10. Answering outside line
a. Answering a call from an outside line is basically the same as answering a station
call.
i. When Command Center is ringing you have the option to pick up the
handset and talk to the party.
1. If you would like to switch to speakerphone, press the SPEAKER
ON/OFF button and place the handset back on the receiver.
ii. You can leave the handset on the receiver and press the SPEAKER ON/OFF
button as well to answer the phone on speakerphone.
1. If you have answered using speakerphone button and want to use
handset, simply lift handset and continue conversation.
b. If the call is from an S3 Communicator, you will need to press 1 to talk to the party
or 2 to listen to the site ID message if the phone is not set to immediate two-way
calling.
BASIC OPERATIONS FROM A STATION
1. Answering Command Center call
a. Answering a call from the Command Center depends on what device is being
called. The main devices that will be attached to the Command Center will be:
i. S3 Communicator - you will not need to do anything at the S3C to answer
this call.
ii. S3 Communicator Master Station - same as the standard S3Communicator,
but you can also lift the handset to talk after the call has been established.
iii. Any POTS telephone connected to the Command Center can pick up and
have immediate two-way calling.
2. Calling Command Center
a. Dial extension 0 from any station connected to the Command Center.

12
3. Ending Command Center call
a. To end a Command Center call from a station depends on the device being called.
i. S3 Communicators will disconnect automatically when the Command
Center ends the call.
ii. Any other phone on the line – place the phone back on the hook or see
what the manufacturer of that particular phone requires to end a call.
4. Holding Command Center call
a. If you are on a phone that is capable of holding a call, you will need to refer to that
manufacturer’s instructions on how to do so. The Command Center extension that
you are connected to will stay on hold indefinitely until you remove the hold.
5. Calling another station
a. To call another station from a station, you must know the extension that the other
station is connected to.
i. You may call only 1 station at a time from any 1 station.
ii. If a station is already on a call, you will get a busy tone notifying you of this
status.
6. Answering station call
a. Refer to “Answering Command Center call”.
7. Ending a station call
a. Refer to “Ending Command Center call”.
8. Calling outside line
a. To connect to an external/outside line, lift the handset off the receiver. When you
hear a dial tone, press 99 to get an outside line, followed by the number you wish
to call.
9. Answering outside line
a. Answering a call from an outside line is much like answering a call from the
Command Center: it depends on what device is being called. Devices that may be
calling are:
i. S3 Communicator - you will not need to do anything at the S3C to answer
this call.
ii. S3 Communicator Master Station - same as standard S3 Communicator,
but you can also lift handset to talk after call has been established.
iii. Any POTS telephone connected to the Command Center can pick up and
have immediate two-way calling.

13

telephone.
1. Press TALK/END.
2. Enter the number of the station you wish to call.
5. Answering calls
a. Calls to an S3C will be answered automatically. When the S3C picks the phone up,
you will hear an audible beep and the LED will start flashing. The call will end
automatically as well and gives you an audible “they have hung up” followed by
the LED shutting off.
CONNECTING TO OTHER COMMAND CENTERS
Calls can be placed from one Command Center to another, similarly to an elevator phone or an
outside line. Additional hardware and cabling is required to accomplish this as shown in figure 1. The
elevator phone block depicts elevator phones capable of sharing a single line as with the Wurtec S3
Communicator phones.
Figure 1: Block diagram representation showing connections required for Command Center to Command
Center communications along with Telco and elevator phone connections.

15
In this scenario Command Center 1 can call Command Center 2 or vice versa via the following steps:
1. Select the extension that the other Command Center is connected to, in this case EXT 001.
2. The other Command Center will answer with its automated response asking for the
number of the phone that you would like to talk to.
3. To ring the other Command Center, directly dial 0.
With S3 Communicators configured to share a line as the elevator phones connected to Command
Center 1, a call can be placed from Command Center 1 to any of the phones via the following steps:
1. Select the extension that the phones are connected to, in this case EXT 003.
2. The S3 Communicators will respond with their automated response asking which phone
(1 – 8 or 0 for all) you want to talk to.
Likewise, to place a call from Command Center 2 to any of the S3 Communicators:
1. Select the extension that the other Command Center is connected to, in this case EXT 001.
2. The other Command Center will answer with its automated response asking for the
number of the phone that you would like to talk to.
3. Dial the extension that the phones are connected to, in this case 3.
4. The S3 Communicators will respond with their automated response asking which phone
(1 – 8 or 0 for all) you want to talk to.
Calling from Command Center 1 to an outside line works the same way as outlined above with a single
Command Center:
1. Dial 99 from the Command Center to get the dial tone from the outside line, then the
number that you want to call.
To place a call to the outside line from Command Center 2 in this scenario:
1. Dial 99 to get a dial tone from Command Center 1.
2. Dial 99 again to get a dial tone from the outside line, then the number that you want to
call.

16

TROUBLESHOOTING
1. Keypad not working
a. Ensure Command Center is powered up.
b. Ensure phone is off hook if you are attempting to use number pad.
2. Arrow keys not working
a. This function is disabled when on a call.
b. Ensure Command Center is powered up.
3. Have a good phone line, but hear a busy tone when attempting to call out
a. You must first dial 99 to get an outside line. If you do not, you will get a busy tone.
b. Make sure the display on the Command Center shows the external line as green
and “0” as the status when phone is on hook.
i. If the external line is displayed as red and has “X” as the status, the
Command Center does not recognize a good line.
ii. Verify you have at least 24VDC on the line.
4. Command Center does not respond to Touch Tone when calling remotely
a. Verify the phone you are using is not set to “pulse” dialing. All S3 products will
only recognize tone dialing.
b. Using a land line telephone, the Command Center should respond to touch tones
with no problems.
c. If using a cell phone, it may be because of bad cell reception or just may not work
at all with some phones. In this case, it is recommended you use a land line or be
onsite to perform any programming.
5. Handset is not working
a. Verify the handset is connected properly to the Command Center and at the base
of handset.
b. If the phone is on speakerphone, the handset is disabled.
i. While phone is on speakerphone, place handset back on receiver.

19
ii. If at some point the Command Center was placed on speaker without
returning the handset back to the receiver, both may not function
properly and you will need to ensure phone is on hook by returning
handset to receiver and turning off speakerphone.
TECHNICAL SUPPORT
Tech support can be reached at [phone] or toll free at [phone], Monday through Friday,
8:00 a.m. to 5:00 p.m. EST>
DAILY CHECKS
The Command Center is intended to be self-sufficient, so minimal maintenance is required to keep it
in operating condition. The Command Center will display any warning messages or error conditions
that are detected until acknowledged, so it should be checked at a minimum of once per day.
MAINTENANCE
The Command Center battery is the only component that will require regular maintenance and should
be replaced at least once every 5 years.
