General Information

GAI-Tronics Centra-Page systems provide dependable paging and party line communications for rugged
and haza rdous industrial fa c ilities. Centr a-P age systems feature centrally-locate d electronics p rovi ding
environ me nta l prot e c tion and unitized a mplification f or eas y maintena nce. S tandard C ent ra- Page central
cabinets can support up to 30 handset stations, and in most cases, up to 60 paging speakers. Alarms and
telephone interfacing can also be added to a Centra-Page system.

The Model 69460-001 Crew’s Quarters Muting Card is used in Centra-Page systems to provide up to
three selected tones and/or s p eech mess ages for broadcast in living areas such as conference rooms and
crew’s quart ers .

The Model 69460-001 Card plugs into the 10461-002 Centra-Page Card Rack in the same manner as a
standard Model 69037-101 Station Card. The 69460-001 is then wired to the selected output on the
Model 10961-001 AMI Centra-Page Interface, which can be used to signal the 69460-001 Card to
broadcast the tone. Jumpers on the Model 10961-001 can select one or all of the three tones to activate
the output to broadcast the alarm on the 69460-001 card.

OTE: The Model 69460-001 Card is for use with speakers only because it does not contain a ha ndset

N

station power supply. To connect a station in the crew’s quarters area, use a standard Model 69037-101
Station Card and do not wire any speakers to the card.

Installation

Jumper Settin gs

The Model 69460-001 Card contains three jumpers (P5, P6, P7). These jumpers set the logic levels of the
card's input control lines to either active HIGH (24 V) or active LOW (0.7 V). For operation in a
standard Central Page system using the Model 10961-001 Interface Panel or Model 10460-002 Interface
Panel, the jumpers must be set to active HIGH. Active HIGH is the factory default setting for all jumpers.
The active LOW setting is used only in special applications in which a custom-designed interface panel is
present or the card is being controlled by a device other than the interface panel. Refer to Figure 1.

Table 1. Jumper Settings

Jumper Function Active High Active Low

P5 Input #1 Short pins 2&3 Short pins 1 & 2
P6 Input #2 Short pins 2&3 Short pins 1 & 2
P7 Input #3 Short pins 2&3 Short pins 1 & 2

Card Rack Installation

1. Open the Centra-Page system central cabinet to access the front panel.

2. Slide the Model 69460-001 Card into the card rack slot associated with the speaker to be muted.

Ensure that the connector at the rear of the card has plugged firmly into the connector in the card
rack.

3. Snap the white clip on the front of the card into place to secure the card in the card rack.

4. Open the Centra-Page cabinet to access the rear of the card rack. Attach the new terminal block label

as noted in Figu re 2.

5. Use No. 14, 16, or 18 AWG cable to complete the connections to the speakers. The distance between

th e centr al c abi net and the speak ers det erm ines the wire gau ge that is requ ire d: t he greater th e
distance to be covered, the larger the wire gauge that is needed. Refer to GAI-Tronics Pub. 42004­135 for more information on speaker installation and wiring.

6. Refer to Figure 2 and Figure 3. The Model 10961-001 AMI Centra-Page Interface is equipped with a

Crew’s Quarters activation output (TBX04 position 9 - the black wire). Connect the black wire from
the 10961-001 TBX04 to the card rack terminal block position 2. Jumpers P1, P2 and P3 on the
69452-001 Interface PCBA are used to control which of the three tones will be broadcast to the
crew’s quarters. The jumper in position 1 and 2 make the tone non-active. The jumper in position 2
and 3 make the tone active. One or all the jumpers can be active. For example, to broadcast tones 1
and 2 only to the crew’s quarters, put P1 and P2 in position 2 and 3 and allow P3 to remain in
position 1 and 2.

Operation

Card Indicators

The card cont ai ns th ree in dicat or L EDs that are visib le f ro m the f ron t of th e card r ack. Th ese L EDs are
used to identify the card functions as follows.

Table 2 - Indicator Functions

LED Color/Position Function

Red (top) 24 V dc power is present on the card.
Green (middle) Audio is present on the speaker output.
Yellow (bottom)

One or more of the control inputs is active, which enables the
speaker output.

Speakers

8-Ohm O ut Operati on

When using the 8-ohm output connections, always use speakers of proper voice coil impedance and
power han d ing capability. Cons ult GA I - Tronics P ub. 42004-135 and 42004-220 for more details on
speaker installation and wiring.

70.7 Vol t Out Op eration

Greater speaker line distances from the central cabinet can be obtained by using the 70.7 V output
connection compared with using 8-ohm output. The individual speaker’s power level is determined by
the tap settings on the line-matching transformer. The use of these transformers allows the speakers to be
placed at longer distances from the central amplifier system without significant power loss.

The sum of the speaker power settings must not exceed the total power available from the amplifier
PCBA. For example, the 69460-001 PCBA’s 70.7 V output (~16 W out with ~27 V dc in) can drive
approximately eight speakers tapped at 2 watts each or four speakers tapped at 4 watts each.

Speaker Wiring Distance Guide

Cable distance should be kept as short as possible to reduce the power loss. The following chart
illustrates the correlation between three typical wire sizes and the distance that speakers with integral
dri vers or horns with sep ara te drivers c an be pl aced from the c e ntral card ra c k for a –1 dB loss (-20%
power loss). For a 0.5 dB loss, divide all lengths in half.
