Installation and Maintenance Instructions
Model G-SND Global Series Sounder
Safety Messages to Installers and Users
It is important to follow all instructions shipped with this product. This
sounder is to be installed by a trained electrician who is thoroughly familiar
with and will follow all applicable national and local codes in the country of
use.
This sounder should be considered a part of the warning system and not the
entire warning system.
The selection of the mounting location for the sounder, its controls and
the routing of the wiring are to be accomplished under the direction of the
facilities engineer and the safety engineer. In addition, listed below are some
other important safety instructions and precautions you should follow:
• Read and understand all instructions before installing or operating this
equipment.
• To avoid electrical shock hazards, do not connect wires when power is
applied. Failure to observe this warning may lead to serious injury or
death.
• Never alter the unit in any manner. Safety in hazardous locations may be
endangered if additional openings or other alterations are made in units
specically designed for use in these locations.
• Do not connect this sounder to the system when power is on.
• All effective warning sounders produce loud sounds, which may
cause, in certain situations, permanent hearing loss. Take appropriate
precautions such as hearing protection. The device should be installed
far enough away from potential listeners to limit their exposure while
still maintaining its effectiveness.
• After installation, ensure that all threaded joints are properly tightened.
• After installation, test the sounder system to ensure that it is operating
properly
• Keep the unit tightly closed when in operation.
• After testing is complete, provide a copy of this instruction sheet to all
personnel.
• Brass inserts have the potential to store charge when they are not
plugged. Consideration should be taken to prevent these from becoming
a sparking hazard.

Installation and Maintenance Instructions
Model G-SND Global Series Sounder
• Establish a procedure to routinely check the sounder system for proper
activation and operation.
• This equipment is suitable for use in Class I, Division 2, Groups A, B,
C, D; Class II, Division 2, Groups F and G; Class III or non-hazardous
locations only.
• WARNING: EXPLOSION HAZARD — Do not disconnect the
equipment unless power has been switched off or unless the area is
known to be non-hazardous.
• WARNING: EXPLOSION HAZARD — Do not remove or replace the
fuse when energized.
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.
With respect to the potential electrostatic charging hazard as mentioned
in the certicate “Specic Conditions of Use”, under normal conditions
of use, these devices are for xed installations and not generally
in contact with people. The risk of ignition is low. In addition,
maintenance, cleaning, and extreme environmental factors (ex. high
velocity dust laden atmospheres or high pressure steam) should be taken
into account by the end user, using local Explosive Atmosphere (Ex)
Electrical installations design, selection, inspection, and maintenance
Codes and Standards. Cleaning of the devices should only be done with
a damp cloth.

Specic Conditions of Use:
1. The Modular Audible Device enclosure incorporates a sinter and
the volume is greater than 100 cm3, therefore use of the Modular
Audible Device in carbon disulphide gas atmospheres is not
permitted.
2. The Modular Audible Device has external non-metallic surfaces
which may provide electrostatic charging hazard. See the
manufacturer's instructions for further information.
3. The Modular Audible Device has metallic components in the nonmetallic walls of the enclosure which can store electrical charge
and therefore may provide a potential electrostatic discharge.
The metallic brass inserts have a capacitance of 24 pF. See the
manufacturer's instructions for further information.
cULus Zone Certications:
The following models are C1, Zone 1 and 21 certied: G-SND-MV-D
and G-SND-MV-T. Models not mentioned are not suitable for Class,
Zone locations.

UL Fire Alarm Certications: See page 30.
Unpacking the Sounder
After unpacking the sounder, examine it for damage that may have
occurred in transit. If it has been damaged, do not attempt to install or
operate it. File a claim immediately with the carrier, stating the extent
of the damage. Carefully check all envelopes, shipping labels, and tags
before removing or discarding them. Disposal of all shipping materials
must be carried out in accordance with national and local codes and
standards. If any parts are missing, please call Federal Signal Customer

Installation and Maintenance Instructions
Model G-SND Global Series Sounder
Creating Combination Fixtures in the Field
The Federal Signal Global Series Ex de products can be connected
together in the eld using interchangeable E-box end caps and a
proprietary coupling system (Figure 1).
Figure 1 Sounder and sounder combination xture
The proprietary coupling system allows for simple and cost effective,
wiring from product to product, often eliminating the need for
expensive Ex wiring practices and Ex rated glands. The E-box is
available only when factory installed on an Ex d unit or when used
as a E-box spacer adjoining an existing E-box. Please refer to the
accessories listed on page 28 for available options. When creating
certain xture combinations, it is necessary to replace E-box end caps
before mounting the product. If you are creating combination xtures,
refer to instruction manual 25500259 for specic instructions and
details.

A note about combination xtures: If the product is Ex db marked
only, it is for use in gas atmospheres. If the product is Ex db e marked,
it uses the increased-safety terminal enclosures and is only for gas
atmospheres. If the product is Ex tb marked, it is for installation in
dust atmospheres.
Mounting the G-SND Sounder
ATTACH THE SOUNDER SECURELY: To prevent injury, this
apparatus must be securely attached to the mounting surface
in accordance with the installation instructions. Use installersupplied fasteners suitable for the mounting surface.
The mounting method and the installer-supplied mounting hardware
depend on which of the two G-SND models you are installing:
Mounting the Surface-Mount Ex d Sounder
Mount the sounder to a at surface using the four 8.5 mm mounting
holes. Use installer-supplied fasteners suitable for the surface to
which the device will be mounted.
