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’ SelfMonitoring and Reporting Telephone (SMART)

flexibility.
When used with the GAI-Tronics’ Telephone
Management Application (TMA) each telephone is
monitored and the status is reported. For complete details,
please refer to the on-line help included with TMA.
This manual applies to the following models:

The GAI-Tronics SMART Telephone product line provides the flexibility to address a diverse range of
applications. A wide variety of functions can be achieved by altering the configuration data stored in the
telephone’s non-volatile memory. These 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)
Maximum call duration
These functions are initially programmed during manufacturing and testing. After installation, they can
be programmed remotely via DTMF data call.
All SMART Telephones are line-powered and can be connected to the 24 V dc or 48 V dc analog station
port of Private Branch Exchange (PBX), Private Automatic Branch Exchange (PABX) or KSU.
Connection may not be made 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 be programmed to generate an auto-dial
maintenance call when certain sensor events are discovered. Access to the SMART Telephone’s
maintenance mode is restricted through the use of the maintenance access PIN. The maintenance access
PIN should be distributed only to trained maintenance personnel.

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 coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and tighten
all cover bolts to 30 ft-lbs. Make certain no cover bolts are omitted. Use only those bolts supplied with
the enclosure.
When installing any GAI-Tronics telephone equipment, please adhere to the following guidelines to
ensure the safety of all personnel:
Electrostatic Discharge (ESD) Protection: Your telephone has an earth ground terminal provision.
Ensure that it is connected to ground in accordance with all local safety regulations and the National
Electrical Code (NEC). Grounding must be ensured for safe and stable communications. Do not use
long and coiled ground wires. Please note proper grounding does not eliminate the need for lightning
protection for the telephone or the telephone system.
NEVER install telephone during a lightning storm.
Install a UL Listed lightning arrestor on any telephone installed where the telephone or telephone
cable is at risk of being exposed to lightning strikes. The lightning arrestor must be installed as close
to the telephone as possible in a non-hazardous environment to maximize the protection. The
lightning arrestor must not be installed 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.
GAI-Tronics’ SMART Telephones are designed to operate on telephone lines as detailed in the “General
Information” section of this manual. The telephones are designed to operate with one telephone per line.
If telephones are operated in parallel or party-line configuration you may experience sporadic telephone
operation, difficulties with programming, or premature disconnection of calls. Additionally, if special
features, e.g. voice mail, call waiting, etc, are not disabled, the telephone may not function.
