Notes: 
I. Use 2 or 3 pair twisted wire to prevent the possibility of crosstalk. 
2. Review Installation Precautions as listed on Page 15. 
3. Stations 9-16 require the imtallation of MT-STUA/A$ or C. See Page 23-24. 
4. Single line telephones require only tip and ring but it is recommended to wire 
single lines just like keyphones so that future upgrading is easier for the installer.

Notes A 
1. For Central Office lines in positions 5,6,7 or 8, MT-STU/A, B or C must be 
installed. For E&M Tie lines in positions 5,6,7 or 8, MT-STU/C must be 
installed. 
2. Incorrect wiring of CO may cause malfunction. If so refer to Troubleshooting 
Section. MT-SKI/A provides 2 CO lines and 4 key telephone circuits. 
l MT-STU/A provides 2 CO lines and 4 key telephone circuits. 
. l MT-STU/B provides 2 CO lines and 4 single line telephone circuits. 
l MT-STU/A provides 2 CO lines and 2 E&M tie lines and 4 key telephone 
circuits. 
3. When connecting a 16H to another 16H, the single line port on one system 
connects to the C.O. line port on the other system. A l-pair wire is needed for 
the connection.

TO INSTALL EXPANSION CARDS 
1. Remove the 4 screws from the main PCB and replace them with the standoffs 
supplied with the expansion board. 
2. Position the expansion card so the modular jacks appear on the left side of the 
KSU. 
3. Plug the ribbon cable into the proper connector on the main PBC. 
4. Secure the expansion card with the 4 screws previously removed. 
5. When installing the expansion card towards the top of the Main PBC, CO lines 
5,6 and Stations 9,10,11 and 12 are added. When installing the expansion card 
towards the bottom of the main PBC, CO lines 7,8 and Stations 13, 14, 
15 and 
16 are added.

3. Plug the 3-pair modular cord supplied with the KSU into the modular plug 
labeled PAGE. 
Connect the Voice pair (blue & yellow wires) to the 600R input of the 
amplifier. 
The black and white wires are dry contact points that can be used, for example, 
to mute background music over page. Connect the black and white wires to the 
mute terminals of the amplifier. (The relay can also be used to ring a bell during 
Common Audible Ring**)

3. Plug the 3-pair modular cord supplied with the KSU into the modular plug 
labeled DOOR. 
Connect the Voice pair (blue 8~ yellow wires) and the power pair (green & red 
wires) to the back of the doorphone. 
The black and white wires are ~IY contacts used to operate customer provided 
electric door lock unit.

							INTERNAL MUSIC SOURCE 
The internal music source of the MT-16H has two selections. To change the internal 
music source refer to Figure

EXTERNAL MUSIC SOURCE 
Although the MT-16H is provided with an internal music source, an external music 
source such as a radio or tape player can be connected to the system. 
TO CONNECT TO A.N EXTERNAL MUSIC SOURCE

1. Connect the external music source to the external music jack using a l/8 in. (3.5 
l ovefvo~ mm) mini photo plug. See Figure 15.

Note: 
1. The MOH plug between the page and the doorphone modular plug (Figure 14) 
is used to turn the external music audio output on and off. The yellow/black 
wires perform this function. When no calls are on hold, the source is turned off. 
No AC voltage. DC voltage only with slave relay! KSU relay rating 
24 vdc, .5 
amp. 
2. Always used shielded cable. 
3. Do not connect radio source to same AC outlet as KSU. 
4. Locate music source a 
minimum of five (5) feet away from KSU to prevent RF1 
interference. 
5. For no music on hold or background music disconnect connector 5 from main 
PCB.

							CONNECTING A PRINTER OR TERMINAL (SMDR) 
A printer or terminal for the purpose of station message detailed recording can be 
connected to the MT-16H. To enable this feature, the optional SMDR card must be 
installed into the system. An RS-232C connector and cable are required for 
connection of the printer orterminaL .- 
1. Install the two plastic standoffs provided with the SMDR card into the KSU 
base. 
2. Insert the RS-232C connector through the hole in the KSU labeled SMDR. 
3. Align the SMDR card with the connector on the main PCB and the 
standoffs. Press card into place.

							POWER FAILURE TRANSFER 
The MT-16H provides up to 6 PFT circuits. On the main PCB, station 7 and 8 can 
be configured as PFT circuits. 
1. 
2. -If-stations 7 and 8 are being used as single line stations on the system, they will 
automatically be connected to CO lines 1 and 2 respectively if dip switches 6 
and 7 are set as follows: 
Dip6-ON-COltoSLT7 
Dip7-ON- CO2toSLT8 
If stations 7 and 8 are being used as key telephones on the system, CO lines 1 
and 2 will be automatically connected to two single line telephones connected to 
the TTC plug on the left side of the KSU. For this scenario to operate, dip 
switches 6 and 7 are set as follows: 
Dip 6 - ON = CO 1 to Tip 1, Ring 1 
Dip7-ON- CO2toTip2,Ring2

In  Note: scenario 2, the SLT’s do not operate until power has 
failed. Any device

When using the MT-STU/B, the first twosingle line circuits are automaticaIIy 
connected to the CO lines served by the MT-STU/B. For example:
