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.

The Model 400-001 and 400-002NS RigCom Stations are designed to be field replacements for the
previous MS39xx Series RigCom stations. As a field replacement for the MS39xx Series, the Model 400
Series must be configured as an unbalanced station.
Along with operation with the MS39xx Series RigCom stations, the Model 400 Series are designed to
operate with the EZ Page Series of GAI-Tronics equipment.

Speaker Horn Assembly (Model 400-001 Only)
After unpacking the unit, locate the speaker horn and the driver unit. The speaker horn assembly must be
put together prior to installation.
Place the speaker bell over the driver bushing. Position two large diameter fiber washers with the large
diameter steel washer sandwiched between them on the speaker bushing. Place the small diameter rubber
washer into the speaker horn tip, followed by the small diameter fiber washer. Screw the speaker horn tip
to the driver bushing until it is snug.
Installation
These enclosures must be installed by trained, qualified and competent personnel. Installation must
comply with state and national regulations, as well as safety practices for this type of equipment.
Model 400-001 and 400-002NS must be installed in accordance with GAI-Tronics Pub. 42004-381,
Control Drawing # 73214.
CAUTION Do not install this equipment in hazardous areas other than those indicated
on the approval listing in the Specifications section of this manual. Such installation may cause a
safety hazard and consequent injury or property damage.
The mounting location must be flat and provide proper clearance, rigidity and strength to support the
enclosure and all contained devices.
Securely fasten the enclosure to the mounting location, using (customer-supplied) 7/16-inch diameter
steel mounting bolts and washers, or washer head bolts.
WARNING
Insure proper grounding to protective earthing.
Do not disconnect equipment while energized.
Inspect and clean the machined flange flame joint surfaces of both the cover and box. Surfaces must be
smooth, free of nicks, scratches, dirt or any foreign particle build-up that would prevent a proper seal.
Surfaces must seat fully against each other to provide a proper explosion-proof joint. Clean surfaces by
wiping with a clean lint-free cloth.
Make certain no cover bolts are omitted. Use only those bolts supplied with the enclosure. Recommended
torque setting of cover bolts = 17 ft-lbs, (23 N-m)

Wiring
Station Wiring
Attach the conduit or cable glands to the ¾ inch NPT holes on the bottom of the enclosure. Feed the low-
voltage wiring conduit on the left side hole, from front view, and the power wiring through the right side
hole, from front view. Attach the wires to the terminal blocks located on the PCBA within the enclosure.
See Figure 4 and charts for connection points and descriptions.
If using the 10438-001 Auxiliary Microphone Assembly, connect the assembly to the station at terminal
block TB4-1 (+) and TB4-2 (-), shield to TB4-5, if used. The maximum distance from the station is 50
feet using No. 18 AWG wire.
If using the 51052-003 Auxiliary Footswitch Assembly, connect the assembly to the station at terminal
block TB4-8 (+) and TB4-9 (-), shield to TB4-5, if used. The maximum distance from the station is 50
feet using No. 18 AWG wire.

System Line Balance
Each system requires termination of the audio pair wires with the 1 kΩ/1-watt resistor assembly included
with each unit. The line balance resistor assembly is made for easy installation into the customer-
supplied junction box. NOTE:Only one line balance resistor assembly is needed per system.
For cable runs that are approximately 4000 feet (1219 m) or longer, it is recommended that the resistor
assembly be installed in a junction box (customer supplied) that is close to the center of the system. Refer
to Figure 5 and Figure 6. The junction box must be suitable for the applicable hazardous location in
which it is located.

System Wiring
The maximum line length for the complete system, while still maintaining maximum output signal, is
15,000 feet for a system with less than ten stations. This is based on No. 18 AWG wire, the stations
spaced equidistantly, and one station in the talk mode at a time. For each station in talk mode, the signal
level reduces by half. For systems with more than ten stations refer to Figure 7 for the maximum line
distance.
