power supplies (such as Models PS8 or PS15) may be
conveniently connected to the SAP612 to distribute power
to
the intercom stations. Or, the SAP612 may be used with
a non-TWpower source. Switchable200-ohmline termina-
tionsare built into the SAP612 for proper line termination
when using a non-TW power source. The SAP612has
two
balanced, wnsformer isolated program inputs. Program 1

2.2 ELECTRICAL WSTAL1,ATION
2.2.1 POWER
NOTE
Most
%W user stations arepowered from channel one,
which is called a "wet" channel because it carries the DC
current in addition to thc channcl 1audio. Channel
2 isa
"dry" channel because it carries audio only. It isimpor-
tant to remember this, since it can have an effect on chan-
nel rissignment later (see pxag~iplrs2.2.1.2 and
2.2.1.3
below for specifics).
ing an additional PSR to the CH
3-4 TNPUT would pennit
channel one assignment to cither buss
1 orbuss 3. Using
threePS8'S would pennit buss 1.1 or
5 to be used for
channel one assignment.) Since
TW power supplies arc
equippedwith termination resistors, set the terniinalion
switcheson the rear panel of the SAP612 to the External
position (switch out).
2.2.1.3 Using other Power Sources(Figure 2-1)
TW systems require 18-35 volts DC (32 volts nominal).
Thepower source must provide adequate filtering soas
not to introduce noise into the system. Connect the exter-
nal power supply ground lead to pin 1 of the CH
1-2
INPUTconnector; connect the positive lead to pin 2. Set
all termination switches tothe Internal (Switched-in) posi-
tion. In this application, buss one is used lo supply powcr
only and cannot be used as an intercom buss. Channel
oneof allexternally powered user stations must he as-
signed to buss ooe.
2.2.1.2 Using TW Power Supplies
22.1.4 System Capacity
Connect
TW power supplies (such as theRTS Models Todetermine power supply loading, add together all of tho
PS8 orPS15)to the
CH 1-6 LNPUT jacks on the back of userstationsthat will bepowered from aparticularbuss(les:;
the SAP612. One to three power supplies may be con- stations which are self-powered). Note: the SAP612 dis-
nected. Using more than onepower supply not only in- tributes DC power, but uses no power itself. Refer to your
crenses the system capacity, hut alsooffeerssomewhat power supply manual for power supply capacity informa-
more flexibility
in chan~~classignment. (ThePS8 and tion.
PSIS supply power on cha~ii~clone, orllin
2, of their out-
put connectors. Therefore, if only onepower supply is
used, all externallypowered user stations must have chan-
nel oneassigned to the singlepowered buss. For ex-
ample, if onePS8 is connected to the CH 1-2
NUT, all
externally powered stationsmusL have channel one per-
m3nently assigned to buss I on the front panel. Connect-

SECTION 3: OPERATION
The front panel ofthe SAP612contains 12pairs of
switches: one pairTor each user station string. The user
slation strings 1-12are identified across the top of the
frontpanel. Channels
1 and 2 for each string arcidcn-
tifled along the bottom of the panel. Buss numbers 1-6
are identifiedto the right of each pair of switches. Assign
an intercomchannel to abuss by settingthe appropriate
switch to the desired buss number.
All channelsassigned
to
a particular buss can intercommunicateand exchange
call signals.
IMPORTANT
I
bch TW user station that receivespower via the
SAP612 must have channel 1 assigned to a
poweredbuss.
