General Information
GAI-Tronics’ Class I, Division 1 VoIP Telephones are constructed of cast aluminum and are
weatherproof and corrosion resistant. User operation is identical to that of a standard analog telephone—
simply lift the handset and dial the desired telephone number.
GAI-Tronics’ VoIP Telephones are designed for connection to a 10/100 BaseT Ethernet, and operate
from either Power-over-Ethernet or an external power source. The VoIP Telephones provide point-topoint communications between personnel throughout a facility over an existing LAN.
This manual applies to the following models:
Model 352-701 Division 1 VoIP Telephone
Model 352-703 Division 1 VoIP Telephone with Headset
In addition to providing standard telephone operation, the VoIP
telephones feature real-time alarm reporting enabling system
supervisors to monitor the telephones’ activity and address
caller needs or maintenance issues immediately. Also, four
user-configurable inputs and two outputs have been provided
for peripheral control.
System Requirements and Limitations
GAI-Tronics VoIP Telephones require Power-over-Ethernet or
a local 24–48 V dc power source for operation. Two VoIP
telephones can be connected in a peer-to-peer configuration
without the need for a LAN, however, a 10/100 BaseT Ethernet
with SIP server is required for systems containing three or more
VoIP Telephones. Conferences are limited by the customer’s
LAN media capabilities and the services available at each end
point.

Tips for VoIP Subscribers
If you have or are thinking of subscribing to an interconnected VoIP service, you should:
Provide your accurate physical address to your interconnected VoIP service provider to ensure that
emergency services can quickly be dispatched to your location.
Be familiar with your VoIP service provider’s procedures for updating your address, and promptly
update address information in the event of a change.
If your power is out or your internet connection is down, be aware that your VoIP service may not
work. Consider installing a backup power supply, maintaining a traditional telephone line, or having
a wireless telephone as a backup.
If you have questions about VoIP in general, see http://www.fcc.gov/cgb/consumerfacts/voip.html.

comply with state and national regulations, as well as safety practices for this type of equipment.
CAUTION
on the approval listing in the “Specifications” section of this manual. Such installation may cause a
safety hazard and consequent injury or property damage.

enclosure and all contained devices.
Do not install this equipment in hazardous areas other than those indicated

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. When the cover bolts are
removed, the cover must be adequately supported.
ATTENTION
Installation should be performed by qualified personnel and only in
accordance with the National Electric al Code 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 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. Trim ground wires to the required length. Please note proper
grounding does not eliminate the need for lightning protection for the telephone or the telephone
system.
NEVER install the telephone during a lightning storm.
Install a Cat5 data line lightning su rge prot ec tor on any phone installed where the phone or phone
cable is at risk of being exposed to lightning strikes. The lightning arrestor must be installed as close
to the phone as possible in a non-hazardous environment. The lightning arrestor must not be installed
within the telephone enclosure.
USE CAUTION when installing or modifying Cat5 data lines.
