Introduction
The GAI-Tronics Centra-Page System provides dependable paging and party line communications for
rugged and hazardous industrial facilities. It features centrally located electronics providing
environmental protection of components. A standard Centra-Page Central Cabinet can support up to 30
handset stations. Alarms and telephone interfacing can also be added to a Centra-Page system.
The Model 473-002 Outdoor Wall Station is used for paging and line communications. When installed
in accordance with control drawing No. 72979, the station provides intrinsically-safe operation in
Class I, Div. 1, Group C and D hazardous areas. Additionally, the station is listed for use in Class I,
Div. 2, Groups C and D; Class II, Div. 2, Groups F and G; and Class III, Div. 2 hazardous areas. The
station, which includes a push-to-page handset and a party line selector, is housed in a weatherproof
enclosure for outdoor installation.
General Information
The Model 473-002 Outdoor Wall Station is housed in a non-metallic, weatherproof, Type 4X housing
measuring 6.88 W
× 10.5 D × 14.58 H inches. See Figure 1 for the dimensions of the station mounting
holes located in the rear section.
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.
