Introduction
GAI-Tronics Centra-Page systems provide dependable paging and party line communications for rugged
and hazardous industrial facilities. Centra-Page systems feature centrally located electronics that provide
environmental protection and unitized amplification for easy maintenance. Standard 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 Model 476-002 Flush-Mount Station is used for paging and party line communications. When
installed in accordance with a control drawing 72979, the station provides intrinsically-safe operation
in Class I, Div. 1, Groups C and D hazardous areas. The station is equipped with a push-to-page
handset and party line selector.
General Information
The Model 476-002 Flush-Mount Station is enclosed in a metallic housing with a front panel measuring 6
H
× 3.5 W inches. See Figure 1 for the dimensions of the wall cutout needed for flush mounting the
station.
Although there is no absolute limit on the number of stations in simultaneous use on a given intercom path
(party line 1 or 2) for a conference-type call, the effectiveness of the sidetone rejection circuit diminishes
and overall performance begins to diminish after four or more stations are connected together. Therefore, it
is recommended that conference-call party line conversations be limited to four simultaneous users.
