Installation and Maintenance Instructions
Model G-SPK Global Series Loudspeaker
Safety Messages to Installers and Users
It is important to follow all instructions shipped with this product.
This loudspeaker 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 loudspeaker should be considered a part of the warning system
and not the entire warning system.
The selection of the mounting location for the loudspeaker, 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.
• 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.
• Never alter the unit in any manner. Safety in hazardous locations
may be endangered if additional openings or other alterations are
made in units specically designed for use in these locations.
• Do not connect this loudspeaker to the system when power/audio
system is on.
• All effective warning speakers 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 loudspeaker system to ensure that it is
operating properly

Installation and Maintenance Instructions
Model G-SPK Global Series Loudspeaker
• Keep the unit tightly closed when in operation.
• After testing is complete, provide a copy of this instruction sheet
to all personnel.
• Establish a procedure to routinely check the loudspeaker system
for proper activation and operation.
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.

Specic 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 non-
metallic 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.

Installation and Maintenance Instructions
Model G-SPK Global Series Loudspeaker
Unpacking the Loudspeaker
After unpacking the loudspeaker, 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
Support at [phone] or [phone].
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.

Installation and Maintenance Instructions
Model G-SPK Global Series Loudspeaker
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 21 for available options. When creating
certain xture combinations, it is necessary to replace the end caps of
E-box before mounting the product. If you are creating combination
xtures, refer to instruction manual 25500259 for specic 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 Loudspeaker
ATTACH THE LOUDSPEAKER SECURELY: To prevent injury, this
apparatus must be securely attached to the mounting surface
in accordance with the installation instructions. Use installer-
supplied fasteners suitable for the mounting surface.
The mounting method and the installer-supplied mounting hardware
depend on which of the three G-SPK models you are installing:
Mounting the Trunnion-Mount Loudspeaker
For the loudspeaker dimensions, see the gures on the next pages.
Mount the trunnion bracket to a at surface using the two 7.0 mm
mounting holes (Figure 2). Use installer-supplied fasteners suitable
for the surface to which the device will be mounted.
