Introduction
The GAI-Tronics Centra-Page system provides dependable paging and party line communications for
rugged and hazardous industrial facilities. Centra-Page features centrally located electronics that provide
environmental protection for components. Standard Centra-Page cabinets can support up to 30 handset
stations. Alarms and telephone interfacing can also be added to Centra-Page systems.
General Information
The Model Centra-Page 10461-002 Card Rack is one of the primary components of a Centra-Page
system. All Centra-Page systems require at least one card rack, which houses the individual line cards
that correspond to specific handset stations and speakers in the system. The card rack contains
termination points for 22 to 28.8 V dc power as well as the alarm/tone generator and the telephone
interface connections.
Each card rack has the capacity for holding up to ten GAI-Tronics Model 69037-101 Line Cards. These
cards plug easily into the rack with the card ejectors at the top and components to the right. The cards are
keyed so that they cannot be plugged in backwards. Centra-Page systems using the Model 10468-002
Centra-Page Central Cabinet have maximum capacity of three card racks and therefore 30 line cards (and
stations). Some large Centra-Page systems involve custom cabinets or other customer-designed
installations.
All of the handset stations and speakers in a Centra-Page system are homerun (individually) wired back to
the card rack(s). Terminations for each station and associated speaker are found in the rear of the card
rack. For wiring information, refer to Figure 1, which illustrates a typical Centra-Page system, to the
Model 10468-002 Centra-Page Central Cabinet manual, Pub. 42004-222, and the individual component
manuals.
When a Model 10961-001 AMI Centra-Page Interface is used in a Centra-Page system, priority encoded
tones are sent over all speakers in the system through the line cards. Refer to Pub. 42004-345 and 42004-
371 for details of operation. Additionally, a telephone line can be connected to the system allowing off-
site personnel to communicate to those in the plant or facility.
