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.

Wiring For Tip & Ring
• After mounting the telephone follow these steps.
• Run tip, ring and ground wires from the local exchange into the lower junction
box. The tip and ring wires must not be connected to the local exchange until
installation is completed. A sealing fitting must be installed within 45.7 cm
(18") on the exchange side of the lower junction box.
• Attach the tip and ring wires to the orange and blue wires from telephone
using twist on wire connectors. Attach #10 ring lugs to the end of the three
green wires and attach these wires to the ground screw in the junction box.
• For tone (DTMF) dialing operation of the telephone, connect the two brown
wires together and protect the connection with a twist-on wire connector. For
pulse dialing operation of the telephone, separate the two brown wires and
insulate the ends to prevent accidental contact with the interior of the junction
box.
• Check the wiring and close the junction box.

Government Certification
Attached to the telephone are labels for Industry Canada and the United States Federal Communications Commission. These identify
equipment certifications indicating the 60 and 70 series telephones meet certain telecommunications network protective, operational
and safety requirements. These agencies do not guarantee the equipment will operate to the user's satisfaction.
Before installing this telephone equipment, users should ensure it is permissible to connect the equipment to facilities of the local
telecommunications company.
Equipment must be installed using acceptable connection methods. In some cases, the telephone users inside wiring, associated with
a single line service, may be extended by a certified connector assembly (telephone extension cord). The customer should be aware
that in some situations compliance with the above conditions may not prevent degradation of service.
Repairs to certified equipment should be made by a supplier designated authorized maintenance facility.
For their own protection users should ensure the electrical ground connections of the power utility, telephone lines and internal
metallic water pipe systems, if present, are connected. This precaution may be particularly important in rural areas.
CAUTION: Users should not attempt to make ground connections, but should contact the appropriate electrical inspection authority
or electrician.
Load Number (LN)
The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop
used by the device. Termination on a loop may consist of any combination of devices subject only to the requirement that the total of
the Load Numbers of all the devices does not exceed 100.
Notification to Telephone Company
Upon request, the customer must notify the telephone company of the particular line to which the connection will be made and provide
the Industry Canada or FCC registration number. The local telephone company may request disconnection of the telephone where
alterations or malfunctions affect the telephone’s performance.
United States Federal Communications Commission
This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the
instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for Class
A computing device pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection against such
interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause
interference in which case the user, at his own expense, will be required to take whatever measures may be required to correct the
interference.
Interference
There is no guarantee that interference will not occur in a particu lar installation. If interference to radio or television reception from this
equipment is suspected, proceed as follows:
1. Unplug the set, check for the interference.
2. Re-orient the receiving antenna.
3. Relocate the set with respect to the receiver.
4. Move the set away from the receiver.
If necessary, consult the supplier or an experienced radio/television technician for additional suggestions.
FCC Rules and Ringer Equivalence Number
This equipment complies with Part 68 of the FCC Rules. On the side of this equipment is a label that contains, among other
information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this information
must be provided to the telephone company.
The REN is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the
telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs
should not exceed five. To be certain of the number of devices that may be connected to the line, as determined by the total RENs,

Avaya Product Return
Avaya products have been quality tested and are in full working order when shipped from the factory, given the
rugged nature of these products, shipping is not expected to damage a unit. In the unlikely event of a
malfunction, Avaya follows the three step procedure below.
Step I - On-Site Correction
• The most common source of difficulties with a new product is improper installation in one of two ways:
incorrect wiring connections or connection to an incorrect po wer source.
• Product wiring needs to be properly connected to the on-site wiring. Correct wiring instructions are shown in
the user manual included with the product.
• Connecting a telephone to a standard power source, rather than tip & ring, will blow the telephone’s internal,
user-replaceable fuse. In the event of fuse burn-out, disconnect the telephone from the power source,
replace the fuse, and reconnect following the wiring diagrams provided with the product.
Step II - Return Materials Authorization (RMA)
• When a product has been installed following user manual instructions, and the unit fails to operate, the user
must contact Avaya to obtain authorization to return the product. This can be done by completing a RMA
form online at www.Avaya.com, or by calling the service telephone number given in this manual.
• After providing information on the product, the owner and the nature of the problem, Avaya will issue a RMA
number, to be shown on documentation returned with the product.
• In addition to the RMA number, shipping documents should include name, address and telephone number
of the owner along with contact information for the person responsible for the re pair and/or the user who
identified the malfunction.
• (Where a product is being returned for repair from outside of USA, customs documentation must show the
product’s serial number, date of export [date of purchase], and a notation that the equipment is: “USA goods
returning.”)
Step III - Factory Authorized Service
• Once received, each product is carefully inspected and tested. If the product is under warranty, repairs are
completed and the product returned to the owner, generally within five working days of receipt by the
factory.
• A product that has been subjected to misuse, neglect or accident or is beyond the warranty period will be
evaluated. The service department will provide the owner’s representative with a repair cost estimate. Once
approved, repairs are completed and the product returned, generally within five working days.
