telephone or it may branch off from a junction box.
See: Figure 3 - Wiring
Alternatives
•Declassify the hazardous location before proceeding with any
installation or electrical wiring.
WARNING
Do not connect this device to any power source other than telephone tip
and ring, doing so will destroy the circuitry and void the warranty.
Caution: Installation or
electrical wiring in a
hazardous location
could result in serious
injury to personnel or
damage to property.
•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. See: Figure 1 - Overall
Dimensions
•Ensure mounting can support 5 lbs (2.3 kgs) and any additional anticipated
load.
•Ensure that none of the electrical connection circuits are live.
•Secure the unit using screws or bolts through the mounting tabs.
•Remove the screw cover.
Tip: Use #8 or M4
screws or equivalent
bolts to secure the unit to
the wall.
•Run tip and ring wiring to the unit using appropriate electrical fittings.
•Attach the telephone tip and ring leads to the terminal strip. See: Figure 2 - Electrical
Connections
•Replace the screw cover ensuring that the faces of the cover and the
enclosure are in contact.
•Apply power to the system.
•Test the unit by calling from another unit on the exchange.
Maintenance
•Declassify the hazardous location or disconnect the line before
proceeding with any maintenance or repairs.
•To maintain hazardous area compliance the only field repair permitted is the
replacement of the driver assembly. All other repairs or alterations must be
carried out by Avaya or an Authorized Service Depot. See Warranty and
Disclaimer for details.
•When replacing the screw cover ensure that the faces of the cover and the

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 power 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 this device to a standard power source, rather than tip & ring, will destroy the circuitry
and void the warranty.
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 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 repair
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.
