Specially designed circuitry and solid state
components eliminate high voltage transient
failures and preventfalse ring-inthrough linein-
duced AC voltages or remote two-wire
telephone instrument dialing. Design
guarantees that 200 miliseconds of ringing
signal will trigger the ring-incircuitry, and also
providesprotectionagainst dropout of holddur-
ing battery reversal.
Equipped with a lightemitting diode to indicate
busy or idle line condition. Also available with
circuitry that protects against false "Dial-1
transfer" withastrapoption for 500msDelayed
Hold Release.
b. SB4100A KTU LlNE CARD FOR OFF-
PREMISES EXTENSIONS
A complete KTU line circuit with the additional
circuitry required to permit duplication of key-
set features and supervision at remote loca-
tions to provide off-premises extension service
with one control pair. Provides means for two,
or more, connected stations to completely con-
trol a telephone circuit. One unit required at
each location. Loop limits 1800 ohms.
C. SB4200A MUSIC-ON-HOLDCARD-
Provides KTU Line Card, Music-On-Hold and
Bell System Interconnect interface (MOH),
(STC) functions all on one 18-pin circuit card.
With these built-in features, installation con-
sists only on connecting of two leads from the
music source to two points on the KTU moun-
ting shelf. No other auxiliary devices or wiring
isrequired. The built-in MOH specification cir-
cuitry provides DC isolation, amplitude limiting
at -12 dbm and at least 85 dbm cross-talk
attenuation. Equipped with LED to indicate
busy or idle condition.
d. SB4201 FM RECEIVER FOR MUSIC-ON-
HOLD
A complete music source designed to be used
in conjunction with SB4200A is normally suffi-
cient to provide service for an entire installa-
tion. Receiver is mounted on a 18-pin KTU line
card-sized circuit board which inserts in any
KTU line card position. Music is transmitted
from the SB4201A to SB4200A line cards on
pins 3 and 18via common straps in the KSU.
Standard KTS manual intercom similar to
WECO 401. Manufactured to SANIBAR's strict
quality control for long, trouble free service.
INSPECTION
Inspectthe unit thoroughly as soon as possible
after delivery. Visually inspect for broken and
loose wires, or chassis damage. If any part of
the unit has been damaged intransit, report the
extent of damage to the transportation com-
pany immediately.
MOUNTING
The SB6630B KTS is designed for wall moun-
ting and should be mounted firmly to a suitable
backboard as required. Three mounting holes
are provided for use with
fh" lag boltsor wood
screws. Clearance isprovided for upto
3/4" O.D.
washers. Locate the desired position for the
KTS and mark the top center keyhole location.
NOTE: The KTS may be mounted as close as
desired to adjacent equipment or ceiling. No
clearance for the hinging of the cover is
required.
Screw the KTS to the wall with the one top
mountinghole,then locate the two lowermoun-
ting holes.
INSTALLERCONNECTIONS
The SB6630B KTS isfactory wired and requires
only minimal amount of installer wiring for
most installations. A prewired connector allows
the power supply to be quickly installed. All
normal user functions appear at the three
feature blockslocatedon the chassis. Figures4
& 5 show the basic wiring for the system and
power unit.
Feature Block Connections
Line cards and special feature cards plug into
the 6 standard 18-pinconnectors. The required
functions appear for distribution at the ap-
propriate locations of the feature blocks.
Card positions 1 thru 6 are wired for standard
line cards (such as the SB4000F or WECO
400D).
a. For card positions 1thru 6, all wiring is per
conventional practice with the following excep-
tions. Pins 3 and 18 appear individually ,at the
feature blocks (rather than bussed) for use on
special function cards. Pin 10 iswired for inter-

rupted 18VACfor buzzers. Pin 11 iswired for in-
terrupted 105VAC for ringers. Therefore either
interrupted buzzer or ringing can be chosen for
common audible by strap option on the line
card. For buzzers, option-T. For ringers, option-
W.
b. Eachof thethree feature blocks iswired for
two circuit card connections as shown below.
Figure 3 gives the functions as they appear at
the blocks.

through either the leftor right cut-outsprovided
inthe cover. (Using the left cut-out may require
that the cord lay over the top of the ring
generator.) The line cord is then plugged into
the 117V, 60
Hz AC supply.
NOTE: Although the chassis and positive bat-
tery are grounded through AC linecord, there is
the possibility of lightning damage due to a
voltage difference to true earth ground. It is
therefore recommended that connection be
made to a good ground. Such as a main cold
water pipe, to binding post El.The largest wire
that Elwill accept is 12 AWG.

CIRCUIT DESCRIPTION
Please refer tothe schematic drawings Figures
4
& 5 for the following descriptions.
SB6610B Power Supply
117VAC isapplied to the primary winding (Blk-
Blk)of transformer TI.The transformer has two
secondary windings. One winding istapped to
provide 10 and 18 VAC which provides the lamp
and buzzer output voltages. The other winding
has an output of 32 VAC which isfull-wave rec-
tified by diode bridge CR1-CR4 to produce
5
4OVDC across capacitor C1. Transistors Q1 and
Q2, together with Zener diode CR5, form a pre-
regulator which keepsaconstant 30VDCacross
the input of VR1. VR1 is an integrated voltage
regulator which maintains a constant 24VDC at
its output. VR1 is internally current limited, so
no output fusing is necessary.
SB6610B-401Ringing Generator
AC linevoltage appears acrossthesplit primary
windings and associated network of T2.
Because of the diode CR1, much more current
flows in one direction than the other, causing
the secondary voltage to have a heavy 30 Hz
component. Capacitor C1 and the secondary
winding are resonant at 30 Hz, so that the out-
put voltage across T2-4 and T2-3 will be an ap-
proximate sine wave, with a fundamental fre-
quency of 30
Hz.
Interrupter
When AC common is applied to the interrupter
on the ST lead, the motor will run. IOVAC,
18VAC and 105VAC are interrupted by cam-
driven contacts to provide Lamp Wink, Lamp
Flash, Interrupted Buzzerand Ringingvoltages.
TESTING
Key Telephone System
Iftrouble isencountered with the SB6630B Key
Telephone System, check that all installer con-
nections or strap options have been made pro-
perly. Refer to the individual circuit card
descriptions for test of the units. The KTS fix-
ture contains noelectrical components that are
normally considered subject to failure.
However, possible wire breakage or poor wire
terminations may be verified using normal con-
tinuity checking procedures with a standard
multimeter (Simpson 263 or equivalent).
Power Supply Assembly
If the system difficulties is determined to be
related to the power unit, make sure that the
system power requirements have not exceeded
the powersupply ratingspecified insection 2.0.
Make sure that the installer connections are
made properly. Verify that the connector is
mating properly. If trouble persists, verify that
all powersupply voltage outputs are present us-
ing a standard multimeter. Refer to the
schematic diagrams for locatingwhere the out-
puts appear. (NOTE: It may be necessary to
removethe power supply from the KTS toverify
the problem if itisdue to shorts
in the system).

If it has been determined that there has been a
card, chassis, or power failure; do not attempt
to make field replacement of electrical parts.
The
SB6630B is warranted for a period of 2
years from date of purchase.
