General Information
GAI-Tronics’ Class I, Division 2 VoIP telephones are constructed of durable glass-reinforced engineered
plastic and are weatherproof rated NEMA 4X. User operation is identical to that of a standard analog
telephone; simply lift the handset and dial the desired telephone number. Autodial telephone models dial
a preprogrammed number when the handset is lifted
from the cradle.
GAI-Tronics’Class I, Division 2 VoIP telephones are
available in wired and wireless versions with two
model types: handset and handset with auxiliary
headset jack (see Table 1).
Wired Div. 2 VoIP telephones connect to a 10/100
BaseT Ethernet network. The telephones are
powered by PoE (Power-over-Ethernet) or an external
ac or dc power source. VoIP telephones provide
point-to-point communication between personnel
throughout a facility over an existing LAN.
WiFi models connect to a WLAN (wireless local area
network) meeting the IEEE 802.11 a/b/g/n standard.
An external ac or dc power source is required for
operation.
In addition to providing SIP telephone operation, Div.
2 VoIP telephones provide real-time alarm reporting.
This enables system supervisors to monitor the telephones’ activity to address caller needs or maintenance
issues immediately. All models also have configurable inputs and outputs.

VoIP Subscriber Tips
For existing and new subscriptions to an interconnected VoIP service provider, the following points
should be addressed:
•Provide accurate physical address information to the VoIP service provider to ensure that emergency
services can quickly be dispatched to the location.
•Be familiar with the VoIP service provider’s procedures for updating the address and promptly update
address information in the event of a change.
•Have a clear understanding of any limitations of the local 911 service.
•Be aware that VoIP telephone services may not work if the power is out or the Internet connection is
down. Consider installing a backup power supply, maintaining a traditional telephone line, or having
a wireless telephone as a backup.
•For questions about interconnected VoIP and 911, or VoIP in general, see

Installation
Important Safety Information
When installing any GAI-Tronics telephone equipment, please adhere to the following guidelines to
ensure the safety of all personnel:
•NEVER install telephone wiring during a lightning storm.
•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.
•Install a UL Listed telephone line suppressor (customer-supplied) on the telephone line.
•Use silicone sealant or equivalent around and inside of all conduit entries
•Install a Cat5 data line lightning surge protector 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.
GAI-Tronics recommends the following precautionary steps to protect the unit during installation:
•Install this unit using appropriate Division 2 wiring methods.
•Run the subscriber line inside conduit to ensure that the unit is vandal resistant.
•Use the conduit entries located on the bottom of the enclosure to prevent any condensation forming
inside the conduit from dripping into the unit. Additionally, using bottom conduit entries makes
water less likely to enter the unit at the conduit connection points.
•Use Teflon™ pipe joint tape or a thread sealing compound around the conduit threads to seal
threaded connections and prevent water from entering into the unit at the conduit location.
•Apply a small amount of silicone sealant inside and around the end of the conduit pipe that is inside
the unit. The sealant helps to prevent any condensation formed inside the conduit from dripping into
the unit. This is especially important when using the conduit entry located on the top of the
enclosure. (Manufacturers of silicon sealant include Dow Corning, Duron, General Electric, and
DuPont.)
•Sealed fittings should be installed at all cable entry points to prevent liquids from entering the unit.
