General Information
The GAI-Tronics Model 400-001 and 400-002NS RigCom Stations are designed for a common-talk, or
master/slave communication system for the following hazardous locations: Model 400-001: Class I, Div.
I, Groups C and D; Model 400-002NS: Class I, Div. I, Groups B, C, and D, when installed in accordance
with GAI-Tronics Pub. 42004-381, Control Drawing #73214. The system provides push-to-talk, release-
to-listen operation, and has a local on/off volume control switch to activate and control the volume level
for each station independently.
The Model 400-001 includes an attached speaker and
driver unit. The Model 400-002NS does not include
the speaker and driver unit, but does have a 1/2-inch
NPT hole to remotely mount and connect the speaker
driver unit to the station.
The RigCom stations have connections for an
auxiliary microphone and footswitch connection for
remote operation from the station itself.
In this operation, the auxiliary microphone replaces
the speaker as the microphone and the auxiliary
footswitch provides the same functionality as the
push-to-talk switch. With the use of auxiliary items,
the approved hazardous locations are reduced to Class
I, Div. I, Group D.

Operation
The operator has access to an on-off/volume control switch and the push-to-talk switch.
The on-off/volume control switch allows the operator to turn the unit on or off and adjust the volume
level in the listen mode. Turn the unit off by turning the switch completely counterclockwise. For
maximum volume adjust the switch completely clockwise.
The push-to-talk switch controls the audio communication between stations. When activated, the push-
to-talk switch allows the operator to send a message to another station. When not activated, the station is
listen mode and the station receives messages from other stations. When a station is configured as a
Slave station, the push-to-talk switch has no function.
Common Line System
In the Common Line configuration, all of the stations are on common talking path and are normally in the
listen mode. When one of the stations has its push-to-talk toggle switch activated, its audio signal is
supplied to the audio lines. All other units receive the audio signal and broadcast the announcement over
their speakers. The push-to-talk switch must be held down as long as the operator talks. Releasing the
switch deactivates the microphone and returns the unit to the listen mode.

Master/Slave System
In the Master/Slave configuration, a Master station controls the talk-listen function of the Slave units
through external control wiring.
When the Master’s push-to-talk is not activated, the Slave stations are in talk mode allowing the Master to
monitor the Slave’s audio. When the Master’s push-to-talk is activated, the Slaves are in listen mode
allowing the Master to transmit audio to the Slave stations. The Slave’s push-to-talk is not operable, and
their operation is hands-free.

Appendix A
Interfacing a Model 400-001 RigCom Station to a MS39xx RigCom
Station System
The Model 400-001 RigCom Station is designed to operate as a field replacement or system addition to
the MS39xx RigCom Stations.
The MS39xx uses an unbalanced system for communication and uses the negative of the audio pair as the
ground reference for the control signal. The Model 400-001 has the ability to operate unbalanced or
balanced. In the balanced system, the audio pair is not ground referenced and the control signal requires a
ground signal.
For interoperability between the Model 400-001 and the MS39xx Series, configure the Model 400-001 for
an unbalanced system by placing the jumper for P3 in the UNBAL position. No changes are required to
the MS39xx Series. For Master/Slave operation, connect AUDIO– to AUDIO (WH), AUDIO+ to
AUDIO (BL) and EXT CONT+ to KEY. For common line only the audio wires require connection.
The following wiring diagrams are for the different configurations for a RigCom system.

Appendix B
Interfacing a Model 400-001 RigCom Station to EZ Page Stations
The Model 400-001 RigCom Station is designed to operate as an addition to a system of EZ Page stations.
The EZ Page Series and Model 400-001 Stations are designed to operate either in balanced or unbalanced
systems. An unbalanced system for communication uses the negative of the audio pair as the ground
reference for the control signal. In the balanced system, the audio pair is not ground referenced and the
control signal requires a ground signal.
For interoperability between the Model 400-001 and the EZ Page Series Stations, configure the 400-001
and the EZ Page identically, balanced or unbalanced, at location of P3 on the Model 400-001 and P5 on
the EZ Page station.
The following are wiring diagrams for the different configurations for a RigCom/EZ Page system.
