Installation and Maintenance Instructions

Safety Messages to Installers and Users

It is important to follow all instructions shipped with this product.
This amplied speaker 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 amplied speaker should be considered a part of the warning
system and not the entire warning system.

The selection of the mounting location for the amplied speaker, 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 specically designed for use in these locations.

• Do not connect this amplied speaker to the system when power
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.

Installation and Maintenance Instructions

• After installation, test the amplied speaker 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.

• Establish a procedure to routinely check the amplied speaker
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.

Installation and Maintenance Instructions

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.

Unpacking the Amplied Speaker

After unpacking the amplied speaker, 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.

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 25 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 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 Amplied Speaker

ATTACH THE AMPLIFIED SPEAKER 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 three G-SPA models you are installing:

Mounting the Trunnion-Mount Amplied speaker

For the amplied speaker dimensions, see Figures 3 on page 9 and
4 on page 10. 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.
