INSTALLER/USER INFORMATION
REGARDING FCC RULES
AND REGULATIONS
This electronic key system complies with Federal Com-
munications Commission (FCC) Rules, Part 68.
The FCC registration label on the KSU contains the
FCC registration number, the ringer equivalence 
num-
:
ber, the model number, and the serial number or produc-
tion date of the system.
NOTIFICATION TO TELEPHONE COMPANY
Unless a telephone operating company provides and in-
stalls the system, the telephone operating company
which provides the lines must be notified before a con-
nection is made to them. The lines (telephone num
bers) involved, the FCC registration number, and the
ringer equivalence number must be provided to the
telephone company. The FCC registration number and
the ringer equivalence number of this equipment are
provided on the label attached to the KSU.
The user/installer is required to notify the telephone
company when final disconnection of this equipment
from the telephone company line occurs.
COMPATIBILITY 
WlTH TELEPHONE NETWORK
When necessary, the telephone operating companyprovides information on the maximum number of
telephones or ringers that can be connected to one fine,
as well as any other applicable technical information.
The telephone operating company can temporarily dis-
continue service and make changes which could effect
the operation of this equipment. They must, however,
provjde adequate notice, in writing, of any future equipment changes that would make the system incom-
patible.
INSTALLATION REQUIREMENTSConnection of the electronic key system to the
telephone lines must be through a universal serviceorder code (USOC) 
outlet jack supplied by the
telephone operating company. If the installation site
does not have the proper outlet, ask the telephone corn
pany business office to install one. The correct outlet
jack for this system is a type 
RJ21X.PARTY LINES AND COIN LINES
Local telephone company regulations may not permit
connections to party lines and win lines by anyone ex-
cept the telephone operating company.
TROUBLESHOOTING
If a service problem occurs, first try to determine if the
trouble is in the on-site system or in the telephone com-
pany equipment. 
						

							IntroductionIM! 66-031
Disconnect all equipment not owned by the telephone
company.If this corrects the problem, the faulty equip-
ment must not be reconnected to the telephone line untilthe problem has been corrected. Any 
trouble that
causes improper operation of the telephone network
may require the telephone company to discontinue ser-
vice to the trouble site after they notify the user of the
reason.
REPAIR 
AUTHORIZATION
FCC regulations do not permit repairof customer owned
equipment by anyone except the manufacturer, their
authorfzed agent, or others who might be authorized by
the FCC. However, routine repairs can be made ac-
cording to the maintenance instructions in this publica-
tion, provided that all FCC restrictions are obeyed.
RADIO FREQUENCY INTERFERENCE
The electronic key system contains incidental radio fre-
quency generating circuitry and, if not installed and
used properly, may cause interference to radio and
television reception. This equipment has been tested
and found to comply with the limits for a Class A corn
puting device pursuant to Subpart J of Part 15 of FCC
Rules. These limits are designed to provide reasonable
protection against such interference when operated in
a commercial environment.Operation of this equipment in a residential area may
cause interference to radio and television reception: in
which case the user is encouraged to take whatever
measures may be required to correct the interference.
If this equipment does cause interference to radio or
television reception, which can be determined by 
tum-
ing the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the fol-
lowing measures: Reorient the television or’ radio’s
receiving antenna, and/or relocate the KSU, the in-
dividual telephone stations, and the radio or TV with
respect to each other.

CHAPTER 2
INSTALLATION
MOUNTING 
CONSIDERATIONS
l
The KSU should be attached vertically to any stur-
dy, flat, surface. It may be vertically rack mounted
if desired.

l
The KSU must be located within six (6) feet of a
proper electrical outlet. The power supply requires
a dedicated 
117VAC  .15 AMP circuit, with a third-
wire ground, supplied to a standard (NEMA 
515R)
electrical outlet.
 l 
The distance between the KSU and the
TELCO/PBX  jacks must be 25 feet or less as per
FCC requirements. A nominal distance of 7 feet is
recommended.
 .
The mounting location must be secure and dry and
have adequate ventilation. The temperature range
of the location must be within 32-122 degrees F 
(O-
50 degrees C), and the relative humidity must be
less than 90 percent non-condensing.
 .
If the mounting surface is damp or if it is concrete
or masonry material, a backboard must be attached
to the mounting surface to be used for KSU mount-
ing. Suitable mounting backboards are available
commercially or can be constructed out of 
l/Binch
plywood cut to size.
 l
Tools and hardware reauired for mountina include:.
.
.
.
.

2.
Fasteners - wood screws (l/4 x 1 -in& round
head), toggle bolts, or wall anchors
Screwdriver -to match fasteners
Electric 
drill  - if prepared holes are required
Connecting tool 
- for fastening wires to a type-
66 connector block.
Crimping tool 
- for 623-type modular plugs
MOUNTING PROCEDURE
Unpack, and carefully inspect all equipment for
 shipping damage. Notify the shipper im-
mediately of any damages found. Verify that
the packages contain all parts and accessories
needed for proper installation and operation.
If a backboard is required at the mounting loca-
 tion, attach it securely to provide a stable
mounting surface for the equipment.

4. 5.
6.Afull scale mounting template is supplied in the
packing box. Hold 
ortape  it to the mounting sur-
face, and mark the location of the mounting holes on the mounting surface as they are lo-
cated on the template. The mounting dimen-
sions are shown on Figure 2-l . .
Drill  holes in the mounting surface of a proper
size to accommodate the hardware being used. If necessary, prepare these holes with inserts,
anchors or other attachment devices as dic-
tated by the type of mounting surface.
Attach the KSU to the mounting surface with
 four (4) screws installed through the KSU
mounting flange and into the mounting surface
holes.
Note that the flange holes are elongated
with an enlargement at one end. This feature allows the mounting screws to be partially in-
 stalled in the mounting surface before the
cabinets are hung on them.

Place the individual telephone stations as
desired and in keeping with accepted industry
and office standards. Currently produced 8

SYSTEM WIRING
System cabling may be routed concealed or visible as
the installation location requires, Good engineering
practices must be observed 
and all applicable building
codes must be adhered to.
Table 2-l and Figures 2-2
through 2-4 illustrate the system wiring and connection
points for the key system.
AC Power Connection
The AC power is applied to the system by connectingthe AC power cord to the standard (NEMA 
515R)
electrical outlet which supplies the dedicated 117VAC
@ 15 AMP electrical power.The following precautions should be taken to help
prevent damage to the system which could be caused
by an electrical over-voltage condition.l
Do not connect the ACpower cord until the in-
stallation has been checked per the SYSTEM
CHECKOUT instructions given at the end of
this Chapter.
l Employ a dedicated lVL!AC 15 AMP circuit,
with a third-wire ground, supplied to a stand-
ard (NEMA 
5-15R) electrical outlet for the AC
power connection.l
A plug-in, powerline surge protectof should be
installed between the 
KSUpowercordand the
AC power 
eiectrkai outlet.
Line Connection
The KSU interface connections for the COlPBX lines
are individual 
mdular jacks. Wiring between the KSU
connectors and the demarcation point connectors is viastandard modular line cord. 
The maximum allowed
tip/ring loop resistance is 1900 ohms from the KSU
modular jack to the CO/PBX equipment.
To help Insure that foreign voltages, which could
appear on the CO lines, do not damage the system,
verify that gas discharge tubes orsimiiarprotection
devices are installed, and properly grounded, in all
connected CO lines.
Statlon Connection
Connections between the KSU and the stations are typi-
cally via type 
66M-xx connector blocks which are cableconnected to the KSU 
50-pin male connectors. The
maximum distance allowed from the KSU to a station is
1500 feet using 
#I24 gauge, twisted-pair cable..
If spare conductors exist in the cables that are run be-
tween the KSU 
66M-xx connector block and the station
f 
						

							IMI 66-031Installation
jacks, it is a good practice to connect them to earth
ground.Doing this may help prevent them from induc-
ing radio frequency and/or AC interference into the 
SYS-tern
The polarity between the individual wires in a par-
ticular voice or data pair is not critical; however do
not connect the voice circuits to the data 
CirCuits.
Cable CIipsEach cabinet-mounted 
50-pin male connector is
equipped with a retaining clip. This clip is designed to
secure the matted connection once it is made. The clip
does this by snapping into a slot on the cable-mounted
connector when it is pressed together with the 
cabinet-
mounted connector. This retaining clip must be pulled
back slightly to un-snap it before the connectors can be
separated.
DSSIBLF Console Connection
The optional DSS/BLF console may be installed at any
station port to work in conjunction with a companion sta-
tion connected to the adjacent port (e.g.; port 10 for sta-
tion and port 11 for console).
The installed distance limit between the KSU and a con-
sole is the same as that specified for a regular station.
Connect all four wires (voice pair and data pair) of the
console cable to the station connector block.
The voice pair connections of the console can be used
simultaneously to enable a PA port function. Refer to
the paragraph in this chapter headed Area Paging In-
terface 
- Station PA Port.Per that discussion, wire a PA
amplifier input to the DSS/BLF console voice-pair at the
connector block clip terminals. Use an audio matching
transformer, as discussed in the referenced paragraph
and Figure 2-3, to provide isolation. If an enable signal
is required with the particular 
PAequipment being used,
the console and PA equipment connections are limited
to station ports 23 and 25.
The 
DSS/BLF console port must be programmed as a
DSSIBLF port (see Chapter 3 for programming details)
before console operation can take place. The console
port must be also programmed as a PA port if a PA
amplifier has been connected to the voice pair as part
of the system.Busy Lamp Field Stations
An optional keyset is available which is equipped with
a 14 station Busy Lamp Field (BLF). Up to eight BLF
stations can be connected to the system. A BLF station
f
can be connected to any odd or even station port in the
system per the following guidelines.
The installed distance between the KSU and the
BLF station must be limited to 1000 feet or less.
The data-line paired station port cannot be used as
a BLF stationconnection or as a regular station
connection. Data-line pairing is: 1 O-l 
1,12-13, 14
15,16-17,18-19,20-21,22-23, and 24-25.
The overload paired station port cannot be used as
a BLF station connection but can be used as a
regular station connection.Overload pairing is: 1 
O-
12, 1%13,14-16,15-17, 18-20,19-21,22-24, and
23-25.
A port, paired in either manner with a BLF station,
can be used as a PA port if desired.
Power Failure Station Connection
The system provides a tip and ring-pair connected to
line 1 as an emergency power failure circuit. This power
failure pair is available at 
clip terminals on connector
block J-l as detailed on Table 2-l and Figure 2-4. A
power failure pair is only active 
durfng a commercial ACpower failure. An industry standard, single-line
telephone, such as a Comdial model 2500-xx, can be
connected to a power failure pair and used to provide
communications capability until the AC power to the
system is restored.
A-Lead Control Device Connection
The KSU can detect an A-lead (A and Al) control sig-
nal when it is applied to lines 7 and 8. An A-lead con-
trol device can be bridge-connected to these lines via
clip terminals on connector block J-2 as detailed on
Table 2-1 and Figure 2-4.
Data Device Connection
When a 
serial data printer is used for SMDR and COS
printout, connect it to clip terminals on connector block
J-l as detailed on Table 2-1 and Figure 2-4.
The distance between the device and the KSU can beup to 500 feet in a quiet electrical environment.
Shielded cable may be required at some sites for long
runs. For longer distances, a limited distance modem
must be used to relay the data communications be-
tween the KSU and the data device.
When preparing a cable for connection to a data device,
refer to the manufacturer’s manual for the equipment
being interfaced, and make the following wiring connec-
tions:
*Wire the KSU RD line (data from printerto wmmon
equipment) to the device TD (transmit data) output
pin,
2-3 
						

							InstallationIMl66-@31
Wire the KSU TD (data to device from KSU) pin to
the device RD (receive data) pin.
Wire the KSU SG (signal ground) pin to the device
SG (signal ground) pin.Wire the KSU CTS (clear-to-send status from
device to KSU) pin to the device FITS (request-to-
send) output pin.
NOTE: The KSUrequires a positive voltage, wtth
respect to signal ground, in order to send data.If required, wire the KSU 
FITS (request-to-sendstatus signal from the KSU to the device) pin to the
device DSR (data-set-ready) input pin.
If required, wire the KSU PG (protective ground)
tine(s) to the device protective ground 
pin(s).
Data Format
Configure the data device to match the following data
format and to receive data at the baud rate that is set
by COS programming.l
7-bit data with 2 stop bits and no panty - fixedl
Baud rate of 110 baud (defautt) - can be changed
to 300 baud through class of service programming.
System Grounding
It is required that a grounding wire, separate from the
three wire AC line cord, be used. A ground stud is to-
cated on the KSU for this purpose.wire #lO or#l2, in-
sulated, solid copper wire between the ground stud and
a 
reliable earth ground such as a metal cold water pipe
or a building frame ground.
Common Audtble and Auxiliary Station interface
Two sets of relay closure drycontact points are avail-
able at the J-l station connector block.l
One set (J-l connections) provides a dry-contactclosure whenever any of the 
TELCOIPBX lines,
connected to the KSU, ring.l
The other set provides a dry-contact closure when-
ever system station 17 rings.
These contact closures track the ringing pattern in bothcases. The contacts are closed during the ringing
period and are open during the silent perfod.
A typical connection is illustrated in Figure 2-2. Refer
to the paragraph headed Area Paging Interface for adiscussion for using these terminals in the 
attemate
paging function.
Do not exceed a I amp at 24 volts (.5amp at 48 volts)
load on these control terminals.
If the load requlre-
ments exceed thls Ilmlt, connect the load through
an external slave relay.
DO NOT CONNECT THESE
CONTROL TERMINALS DIRECTLY TO THE 
117VAC
LINE.24 
						

							IMI 66-031Installation
Area 
Paging Interface - Station PA Port
A station port can be configured by class of service
programming to be a PA port. As a PA port, it can be
used to couple a station voice path to an external device
(see Chapter 3 for programming details).
The audio input of an external paging amplifier can
be connected to the audio pair of the station port as
illustrated in Figure 2-3.
The audio input connection must be isolated with a
600 ohm to 600 ohm audio matching transformer.
Terminate the audio input of the paging amplifier
with a 620 ohm (nominal value) resistor.
If station port 23 is programmed as a PA port, the
Common Audible contact points are automatically
reconfigured as PA enable terminals. The contact
closure now occurs when PA station 23 is dialed.
The normal common audible function, as discussed
previously, is disabled as long as station 23 is a PA
station.
If station port 25 is programmed as a PA port, the
Auxiliary Station Interface (station 17 audible) con-
tact points are automatically reconfigured as PA
enable terminals. The contact closure now occurs
when PA station 25 is dialed. The normal auxiliary
station interface function, as discussed previously,
is disabled as long as station 25 is a PA station.
Area Paging Interface - Llne Port
A fine port can be configured by COS programming to
be an AUXILIARY port. As an AUXILIARY port, it can
be used to couple a station voice path to an external
device. This is done from any station with that tine ap-
pearance by pressing the proper line key to select the
AUXILIARY port.
DTMF tones or dial pulses can be
dialed through the AUXILIARY port as needed.l
The audio input of an external paging amplifier can
be connected to the tip and ring leads of the line
Poe*l
The audio input connection must be isolated with a
600 ohm to 600 ohm audio matching transformer.
Terminate the audio input of the paging amplifier
with a 620 ohm (nominal value) resistor.A DTMF tone select, zone-paging amplifier can be
employed if desired.If used, the zone-select code must
be dialed after the AUXILIARY port line select key is
pressed.
Musk On Hold
If music on hold is to be part of the system, connect aKX registered music source to the KSU input jack
(phono jack) provided for this purpose. The impedance
of this input is approximately 500 ohms. Level adjust-
ment of the music source may be necessary. This may
be done during system checkout.
