Confidentiality Notice
This installation, operation, and maintenance manual contains sensitive business and technical
information that is confidential and proprietary to GAI-Tronics. GAI-Tronics retains all intellectual
property and other rights in or to the information contained herein. Use this information only in
connection with the operation of your GAI-Tronics product or system. Do not disclose this manual in any
form, in whole or in part, directly or indirectly, to any third party.
General Information
GAI-Tronics’ Class I, Division 1 SMART Hazardous
Area telephones are constructed of cast aluminum and
are weatherproof and corrosion resistant. They combine
standard telephone operation with GAI-Tronics’
SMART (self-monitoring and reporting telephone)
technology to provide optimum performance and
flexibility.
Using GAI-Tronics’ TMA (Telephone Management
application) (purchased separately) provides status
monitoring and reporting for each telephone. For
complete details, please refer to the TMA’s on-line
help.
This manual applies to the following models:
•Model 352-101—Division 1 SMART Hazardous
Area Telephone
•Model 352-102—Division 1 SMART Hazardous
Area Telephone with Ring Relay
•Model 352-103—Division 1 SMART Hazardous
Area Telephone with Headset
•Model 352-104—Division 1 SMART Hazardous Area Telephone with Ring Relay and Headset
GAI-Tronics’ SMART telephone product line provides flexibility to address a diverse range of
applications. Altering the configuration data, in the telephone’s non-volatile memory, achieves a wide
variety of functions. The configuration options include:
•call progress detection, control, and call logging,
•auto-calling, auto-answering, and auto-dialing facilities,
•function inhibiting (e.g., tone pad and manual keypad dialing), and
•maximum call duration.

GAI-Tronics initially programs these functions during manufacturing and testing. Reprogram them
remotely, if necessary, via DTMF data call, after installation.
All SMART telephones receive power from the telephone line for connection to a 24 V dc or 48 V dc
analog station port of a PBX (Private Branch Exchange), PABX (Private Automatic Branch Exchange) or
KSU (Key Service Unit).
Do not make connections to pay telephone extensions or shared service (party) lines.
TMA users can schedule auto-dial maintenance calls to alert maintenance personnel of any unusual sensor
or fault conditions that exist. SMART telephones can also generate an auto-dial maintenance call upon
discovery of certain sensor events. Use of a maintenance access PIN restricts access to the SMART
telephone’s maintenance mode. Distribute the maintenance access PIN only to trained and authorized
maintenance personnel.
Hardware Description
External
Models 352-101 and 352-102 include a handset with approved cable gland, standard keypad, volume
control button, and applicable approval labeling. The handset rests on a cradle, which has a magnetic reed
switch, behind it, to signal off-hook conditions. Ten cover mounting bolts, around the perimeter of the
enclosure’s flange, seal the enclosure (see Figure 2).

For the Division 1 SMART telephone models with the headset option, a removable headset and headset
activation bracket replace the cradle and handset.

Internal
All standard components mount to the rear of the front cover, except for the ring relay PCBA (when
installed) (see Figure 4).
WARNING
—The front cover is not hinged to the rear enclosure. Adequately support the cover
when removing the flange bolts.

Ring Relay PCBA
The ring relay PCBA allows the telephone to activate an external beacon or sounder when the telephone
receives a call. The ring relay PCBA connects to the main PCBA via a two-wire cable assembly. This
cable assembly allows communication between the main PCBA and the ring relay PCBA. The ring relay
PCBA is in the rear enclosure (see Figure 4 for mounting, and steps 3 through 5 in the Wiring section).
Installation
Installation Guidelines
Only trained, qualified, and competent personnel shall install these enclosures. Installation must comply
with state and national regulations, as well as safety practices for this type of equipment.
CAUTION
—Do not install this equipment in hazardous areas other than those indicated
in the Approvals 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 internal devices.
WARNING
—Securely fasten the enclosure to the mounting location, using 3/8-inch diameter
steel mounting bolts and washers, or washer head bolts.
WARNING
—Do not disconnect equipment while energized.
Insure proper grounding to protective earthing.

WARNING
—The front cover is not hinged to the rear enclosure.
Securely support the front cover while removing the cover bolts.
ATTENTION
—Only qualified personnel shall install this equipment, which must be in
accordance with the NEC (National Electrical Code) and/or applicable local
codes.
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.
Apply a light coating of Killark LUBG lubricant to the flange surfaces and close the cover. Install and
tighten all cover bolts to 30 ft-lb. Do NOT omit any cover bolts. Use only the bolts supplied with the
enclosure.
Adhere to the following guidelines when installing GAI-Tronics telephone equipment to ensure the safety
of all personnel:
•Electrostatic Discharge (ESD) Protection: These telephones have an earth ground terminal.
Connect this terminal to earth ground in accordance with all local safety regulations and the NEC
(National Electrical Code). Safe and stable communications require proper grounding. Do not use
long and coiled ground wires.
NOTE:Proper grounding does not eliminate the need for lightning protection for the telephone or the
telephone system.
•NEVER install a telephone during a lightning storm.
•Install a UL Listed lightning arrestor on any telephone where the telephone or telephone cable is at
risk of exposure to lightning strikes. Install the lightning arrestor as close to the telephone as possible,
in a non-hazardous environment, to maximize the protection. Do NOT install the lightning arrestor
within the enclosure supplied with the telephone.
•NEVER install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•NEVER touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•USE CAUTION when installing or modifying telephone lines.
The General Information section details the types of telephone lines that GAI-Tronics’ SMART
telephones operate on. These telephones only operate with one telephone per line. Operating telephones in
parallel or in a party-line configuration may cause sporadic telephone operation, difficulties with
programming, or premature disconnection of calls. Additionally, if unique features, e.g., voice mail, call
waiting, etc., are not disabled, the telephone may not function.
Front Cover Removal
WARNING
—The front cover is not hinged to the rear enclosure. Adequately support the cover
while removing the cover bolts.
1. Support the front cover and remove the ten cover bolts from the enclosure flange.
2. Pull the front cover far enough away to expose the internal connections.
3. Place the front cover aside.
