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.
