Introduction
GAI-Tronics Centra-Page system provides dependable paging and party line communications for rugged
and haza rdous industrial fac ilit ies. Centr a-P age fea tur e s central ly-lo c ated electronics that provi de
environmental protection and unitized amplification for easy maintenance. Standard Model 10468-002
Centra-Page 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 Centra-Page systems.
The heart of the syst em is a centrally- located card r ack containing pri nted circuit board assembli es
(PCBAs) Model 69037-101. One plug-in PCBA, also referred to as a line card, is placed in the central
card rac k ass e mb ly for each independ e nt statio n and sp eaker. Ea c h line ca rd contai ns a handset dc po w er
source, dual-switching relays and a 16-watt speaker amplifier with 8-ohm and 70.7 V line outputs.
Additionally, each card has a paging-level speaker volume control (which does not
level), and a removable link to silence the speaker amplifier for page calls from that station, preventing
acoustic feedback. Each card also contains five LED indicators for operating condition or mode.
The Model 69037-101 Station Line Card plugs into a Model 10461-002 Centra-Page Card Rack located
in the central cabinet. The central cabinet is installed in a non-hazardous area. The Model 69037-101
contains both the handset amplifier power supply and an amplifier for an associated speaker or
horn/driver combination.
As shown in Figure 2, the LEDs located along the edge of the card allow a technician to easily perform
tr oubleshooting at th e central cabin et. Ea c h line ca rd conta ins a 16-wat t audio amplifier fed f rom the
page line bus that is intended to drive loudspeakers in the vicinity of the handset station. There is a
volume control and mute link on the input to each amplifier. The control and link are actually located on
the 10461-002 Card Rack so adjustments for various locations are maintained even though line cards are
replaced or exchanged.

The function of the mutin g is to silence th e l oudspeak ers in the vi cinity of a handset stat ion when p age
calls are initia ted fr om that sta tion. This prevents acoustic feedback w hich ma y be a proble m depe nding
on loudspeaker location. The equipment is not configured for this option when shipped from the factory.
If the muting feature is desired, please refer to the 10461-002 Card Rack manual for instructions on how
to enable this option.
Installation
1. Open the Centra-Page cabinet to access the front panel.
2. Slide the 69037-101 card into the grooves associated with the
proper station. Make sure that the conn ector at t he rear of th e
card has plugged firmly into the connector in the card rack. All
the components should face to the right. The card is keyed so
that it cannot be plugged in backwards.
3. Snap the white clip on the front of the ca rd in to pla ce t o sec ure
the card in the card rack.
4. Open the Centra-Page cabinet to access the rear of the card
rack.
5. Refer to Figure 1. Complete the connections to the terminal
blocks a s noted.
6. Make the connections to the speakers using 14, 16, or 18AWG

cable. The gauge of wire needed is determined by the distance
betwe en the cent ral cabinet and the sp eakers . Th e l arger the wire gauge, the greater the dista nce t h at
can be covered
7. Adjust the speaker level using a small standard screwdriver inserted into the hole labeled SPKR.

Card Status LED Indica tors
The following tables illustrate how to determine the status of the station card based on the combination of
the LED indicators that are lit.
Speaker Amplif ier Status
CR23 (red) is the “in use” indicator, and CR24 (green) is the speaker amplifier power indicator.
Speaker Amplifier Status
CR23
(Red)
CR24
(Green)
Speaker Amplifier Power Off Off* Off
Speaker Amplifier Fuse (F1) is Open Off* Off
Speaker Amplifier On – No audio Off On
Speaker Amplifier On – Audio Signal Present Modulated by audio signal On
With no audio present – Speaker Amplifier Failure On On
*CR24 is a power indicator for the speaker amplifier. When CR24 is off, CR23 must be off.
Handset Status
CR13 (red) and CR15 (yellow) are the handset status indicators, and CR16 (green) is the handset power
indicator.

Speakers
8-Ohm Out Opera tion
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 Volt Out Operation
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 69037-101 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 W iring Distanc e 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.
