Overview
Model EA401 Explosive Atmosphere Telephone
This Explosive Atmosphere telephone provides safe and reliable communication in hazardous
locations, up to and including Class I Division 1. Only standard wiring and fittings are required to
connect the telephone to the system; no barrier is necessary. Since the heavy duty cast aluminum
enclosure is basically soundproof, an external device to signal incoming calls is required.
Features
Enclosure
• cast copper free aluminum with powder coat finish
Internal Sealed Cavities
• completely seal the unit
Keypad
• standard configuration with an additional row of buttons for Last
Number Redial, Link/Flash to access PABX features and Line Release
to duplicate hanging up the handset
• one inch diameter buttons for gloves-on operation
Circuitry Coating
• circuit boards have a UV cured epoxy coating which provides protection
from corrosive agents such as H
with high humidity
Magnetic Reed Hook Switch
• no moving parts, activates when the handset is removed from or placed
in the telephone cradle
Tone (DTMF) Operation
• selectable in the field; factory set to operate to tone (DTMF) exchanges
Intrinsically Safe Handset Operation
• the output from the telephone to the handset passes through an
intrinsically safe barrier ensuring a high degree of safety
Field Replaceable Handset
• the 10’ handset cord is designed for industrial applications and is
attached to the telephone by a connector for ease of replacement
Field Replaceable Fuse
• a fitting in the bottom of the enclosure provides access to the fuse
Hearing-Aid Compatibility
• the handset is compatible with inductively coupled hearing-aid devices

Installation and Operation
Model EA401
Warnings
• In no case should this telephone apparatus or wiring be installed in a location where
acetylene may be present in the atmosphere.
• Two back cover retaining bolts on the model EA401 are factory sealed. Damage to the
seals voids the warranty and safety approvals, and may compromise unit safety.
• It is the responsibility of the installer to advise a supervisor if any telephone equipment or
wiring in a hazardous location may not comply with regulations and standards applicable to
that location.
• Avoid creating a spark by striking tools or metal objects together, against concrete, stone, or
any similar substance.
• Test equipment capable of producing an electric spark must not be used in an explosive
atmosphere.
• All apparatus should be completely assembled and properly sealed before reconnecting
power.
General Requirements
• A EA401 telephone should only be installed with proper authorization. It is necessary for
the customer and the telephone company to have a definite agreement regarding the
location of the telephone unit, auxiliary apparatus, and protector (i.e. lightning arrestor at the
demarcation block).
NOTE:
• To maintain maximum protection, broken or worn parts must be replaced immediately. Any
abnormal conditions should be immediately corrected. Periodic inspections are
recommended.
• Unless otherwise specified, the customer must provide and install explosion-proof conduit
and fittings approved by the Canadian Standards Association (CSA) or listed by
Underwriters Laboratories (UL). The customer is also responsible for having the system
inspected and approved by the appropriate electrical inspector in accordance with local
legal requirements and National Electrical Code Standards.
• EA401 telephone sets and associated external bells and control relays are designed to
provide security against ignition of the surrounding atmosphere. All parts of the apparatus
which might produce an electrical spark are completely enclosed. All passages to the
outside are made such that any spark or flame will be cooled to a temperature below the
ignition threshold before reaching the outside atmosphere.
• If the handset or cord is damaged, it must be replaced with part EA10H handset assembly.
Handsets and cords are not covered under warranty other than to be free of defects at time
of installation.
• If the telephone is found to be defective or in need of repair, it must be returned to the
manufacturer. No field repair is possible other than replacement of the handset and fuse.
• Telephones in good condition may be moved from one location to another.

Installation and Operation
Model EA401
Installing the EA401
• Declassify the hazardous location before proceeding with any
installation or electrical wiring.
• Follow all appropriate electrical codes and use only approved electrical
fittings for the installation.
• Choose a wall location that is free of obstructions and permits space for ½”
NPT conduit runs
• Ensure mounting can support 16.5lbs. (7.5kg), plus the weight of any
peripheral equipment.
• Ensure that none of the electrical connection circuits are live.
• Use the template provided to locate and drill holes for mounting screws.
Use ¼” bolts or screws to mount the unit.
• Secure the unit to the wall:
• Attach lower conduit nipples to the telephone and ensure a minimum five
thread engagement.
• Mount an approved explosion proof junction box within 45.7 cm (18") of the
telephone’s lower sealing cavity and bring telephone wires into this box.
Caution: Installation or
electrical wiring in a
hazardous location
could result in serious
injury to personnel or
damage to property.
See: Figure 3 - Typical
Installation.
See: Figure 2 Dimensions.
Tip: Use ¼” bolts or
screws to secure the unit
to the wall.
Tip: Fittings compatible
with 1/2 inch NPT
nipples, conduit, or 1/2
inch explosion-proof
flexible couplings not
exceeding 45.7 mm (18
inches) may be fitted
directly.
