The mounting location must be flat and provide proper clearance, rigidity and strength to support the
enclosure and all contained 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. 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. 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 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
telephone as possible in a non-hazardous environment to maximize the protection. The lightning
arrestor must not be installed within the telephone enclosure.
• 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.

Mounting
NOTE: The mounting surface must be able to support the 28-lbs. weight of the telephone.
The enclosure must be securely fastened with 3/8-inch diameter steel mounting bolts located on all four
mounting feet. Stainless steel hardware is recommended in outdoor applications. Refer to Figure 2. The
suggested mounting height is 48 inches to the bottom of the enclosure.
OTE: Refer to the Killark Installation, Operation, and Maintenance Data Sheet enclosed with the unit
N
for additional enclosure information.
Figure 2. Model 352 Series Division 1 Telephone Enclosure Mounting Details
Cable Entries
Refer to Figure 3 for the NPT conduit entries. Ensure any unused openings are sealed with proper fittings
per local standards. Use field wiring suitable for the ambient temperature. Any conduit NPT plugs
(blanking elements) must be explosion-proof with a Type 4X rating.

Hardware Description
External
Models 352-001 and 352-002 each contain 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 to signal an off-hook condition. The enclosure is sealed with ten cover mounting bolts
located around the perimeter of the enclosure’s flange. See Figure 4.

Ring Relay PCBA
The Ring Relay PCBA allows the telephone to activate an external beacon or sounder when the telephone
receives a call. When installed, the Ring Relay PCBA is connected to the main PCBA via a USOC
RJ11C modular connector cord. This allows the telephone input wiring to be connected directly to the
Ring Relay PCBA. The Ring Relay PCBA is located in the rear enclosure. See Figure 6 for mounting,
and steps 3 through 5 in the “Wiring” section.

Wiring
WARNING
The front cover is not hinged to the rear enclosure. When the cover bolts are
removed, the cover must be adequately supported.
1. While supporting the front cover, remove the ten cover bolts on the enclosure flange. Pull the front
cover far enough away to expose the internal connections and disconnect any wiring between the
front cover and rear enclosure. Place the front cover aside.
2. Connect the incoming subscriber line or the telephone line suppressor (if applicable) to TB1 on the
main PCBA. If there is not a Ring Relay PCBA present, see Figure 7.

4. Connect the external sounder or beacon to TB2, for activation with an incoming telephone call.
5. Reconnect the USOC RJ11C modular connector cord to the Ring Relay PCBA, from the main PCBA
on the front panel, before reattaching the front cover.
WARNING
Any external equipment connected to the Ring Relay PCBA must be rated for the
hazardous area where it will be located. Improper installation or equipment may cause a safety hazard
and consequent injury or property damage.
Volume Control Jumper Setting
The handset receiver volume control is factory set to default to its original setting (0 dB) when the
telephone is hung up. To save the volume control setting, jumper J4, which is factory set at positions 2
and 3, must be moved to positions 1 and 2. Refer to Figure 7 for the location of J4.

Attach the Front Cover
After all adjustments have been completed, inspect and clean the machined flange 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.
