Installation
ATTENTION
—Installation should be performed by qualified personnel and only in
accordance with the National Electrical Code or applicable local codes.
Safety Guidelines
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.
•
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
as possible to maximize the protection. It must not be installed within the enclosure supplied with the
telephone. Please consult our Service Center at 800-492-1212 for further information.
•
Do not install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•
Do not touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
Security Hardware
Models 227-001, 277-001, 277-002BH, and 277-002BHAC are vandal resistant. The front panel of each
of these models is attached to its enclosure with security screws. A GAI-Tronics Model 233-001 Security
Screwdriver or Torx T-25 security head tip (sold separately) is necessary to install the security screws.
Model 247-001 and 257-001 Telephones’ front panels are attached with standard Phillips head screws.
Conduit Installation Details
(Applicable to Models 247-001 and 257-001)
GAI-Tronics recommends installing telephone lines in conduit to protect against accidental damage and
vandalism. The following measures help prevent moisture from entering the enclosure (see Figure 1 and
Figure 2):
•
Conduit should enter the enclosure from the bottom whenever possible.
•
Sealed fittings should be installed at all cable entry points.
•
Silicone sealant or equivalent should be applied around and inside all conduit entries to prevent
moisture ingress.
