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 and unitized amplification for easy maintenance.

The Model 10468-002 Central Cabinet, a central component of a Centra-Page System, is designed to
house up to three Model 10461-002 Card Racks. A Model 10959-208 Audio Messenger Interface (AMI)
and a Model 10961-101 AMI Centra-Page Interface can also be added. Each of the three card racks can
support up to 10 line cards, and each line card supports one station. For ease of wiring, the central cabinet
offers terminal blocks for power and for remote connection of alarm and interface activation switches.

General Information

The Model 10468-002 Central Cabinet is a double-hinged, three-section, wall-mounted cabinet measuring

20.625 W × 18.5 D × 31 H inches. Use the supplied key to open the lockable front door and expose the
front of the center section.

The center section contains the card rack assemblies and has space for an optional Model 10959-208 AMI
and a Model 10961-101 AMI Centra-Page Interface. Swing the hinged center section open for easy
access to the rear of these components, cable connections, and individual volume adjustments.

See Figure 3 for the dimensions of the cabinet mounting holes located in the rear section. Ensure that the
mounting structure selected is sufficient to support the 165 lbs. (74.8 kg) weight of the fully equipped
cabinet. The rear section contains the term inal block s for the ind iv idual stat ion fi e ld wiring.

The cabinet is designed for input and output cables to enter at the top and bottom of the rear section. The
top and bottom each contain six knockouts for cable glands.

Hazardous Areas

The Model 10468-002 Central Cabinet must

be mounted in a non-hazardous area, although other portions
of the Centra-Page system may be located in Div. I or Div. II hazardous areas if appropriate wiring
configurations and barriers are used. Refer to Pub. 42004-356, Control Drawing 72979, for proper
installation of stations for intrinsically safe operation in Class I, Div. I, Group C and D hazardous areas.

A typical Centra-Page System with components in both hazardous and non-hazardous areas is shown in
Figure 1.

Installation

Install the Model 10468-002 Central Cabinet as follows:

1. Carefully unpack and identify the various components. A parts envelope is included containing

screws and washers for mounting cabinet components. Two front door keys are packaged separately.

2. Determine which of cabling knockouts will be used and remove them before mounting the cabinet.

Refer to Figure 2.

3. Mount the cabinet to the wall using the mounting holes in the rear section. A fully-equipped cabinet

weighs approximately 165 lbs. (74.8 kg) and must be mounted accordingly.

4. The standard cabinet is factory assembled and pre-wired. Wiring for power must be provided to the

cabinet, along with any associated loudspeaker and handset stations cables. Bring all field wiring into
the terminal blocks in the rear section through the cable knockouts.

5. Connect the individual handset stations (L1, L2, P, A) and the paging speakers (C, 8 ohm, 70 V) to

the terminal blocks in the wall-mounted rear section of the Model 10468-002 Central Cabinet. The
three rows of ten terminal blocks can support a total of 30 stations. Refer to Figure 4 for an example
of the typical terminal block wiring connections.

6. Make the necessary connections to the three terminal blocks located in the rear wall-mounted section

of the central cabinet labeled P

OWER, ALARM, and INTERFACE. Refer to Figure 4 and Figure 5 for

the wire color-coding. Their functions are as follows:

• TB11 (P

OWER) provides connection of the 21 to 28 V dc negative ground power supply (35

amps maximum).

• TB12 (A

• TB13 (I

LARM) is for remotely mounted alarm switches (normally open/momentary contact).

NTERFACE) is for remotely mounted switches (normally open/momentary contact) for

telephone access, disconnect, and mode select.

N

OTE: If the central cabinet is in a location where the equipment front panels can not be accessed,

remote auxiliary switches can be connected to perform the access, disconnect, and mode select functions.
Since the currents and voltages are very low, almost any kind of momentary, normally-open switch can be
used.
