Safety Message to Installers, Operators, and
Maintenance Personnel
It is important to follow all instructions shipped with this product. This
device is to be installed by a trained electrician who is thoroughly
familiar with local codes.
The selection of the mounting location for the device, its controls and
the routing of the wiring is 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.
• Do not connect this unit to the system while the power is on.
• All effective warning speakers produce loud sounds, which
may cause in certain situations, permanent hearing loss. You
should take appropriate precautions such as wearing hearing
protection.
• All effective warning speakers produce loud sounds, which may
cause, in certain situations, permanent hearing loss. The device
should be installed far enough away from potential listeners to
limit their exposure while still maintaining its effectiveness.
• After installation, test the sound system to ensure that it operates
properly.
• After testing is complete, provide a copy of these instructions to
all operating personnel.
• Establish a procedure to routinely check the speaker installation
for integrity and proper operation. Any maintenance must be
performed by a trained electrician in accordance with NEC
guidelines and local codes.
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.

120 Series Loudspeakers and Sounder
An Overview of the 120 Series
The Federal Signal 120 Series Loudspeaker complies with the ATEX
Directive for operation in gaseous hazardous areas classied as
Zone 1 with a temperature classication of –20 °C to +70 °C T4, –20 °C
to +55 °C T5, and –20 °C to +40 °C T6.
The loudspeakers are designed for use in industrial public address
and general alarm applications where ATEX certication is required.
They are available in either an ATEX Zone 1 explosion-proof version
or a CE compliant, marine-grade industrial version.
The Model 120 Series Loudspeaker, including the marine versions
(loudspeaker and MS1), has a main enclosure with dual gland entries
and an FLP end cap. The model is tted with a nose cone, outer and
inner horn, driver, and an adjustable mounting bracket. The compo-
nents within the main enclosure—transformer, transformer and PCB
Assembly, PCB—vary depending on the model.
The 25-watt loudspeakers provide an appropriate amount of sound
for the ambient environment. Each speaker is transformer-coupled to
ne tune the sound output for each application and balance the audio
load. Available audio inputs are 100 Vrms, 70 Vrms, and 8 ohms.
A stainless-steel ratcheted mounting bracket locks the sounder in
position at a specic angle without slipping. The bottom surface of
the mounting bracket also contains three mounting holes, to adapt to
a variety of surfaces.
The loudspeaker is rated for IP66/67 according to EN60529 through
the use of a neoprene O-ring seal. All exterior cast aluminum surfac-
es are nished in powder coat paint and external hardware is manu-
factured from stainless steel to resist corrosion.

Special Conditions for Safe Use
To maintain the loudspeaker certication, do not attempt to repair
the ameproof enclosure. Units requiring repair to the ameproof
enclosure must be returned to Federal Signal for service.
The maximum ame path gap for the IIB variants is the same as
for gas group IIC.
All terminal screws, used or unused, must be tightened 0.5 N • m
to 0.7 N • m.
Condições especiais para o Uso Seguro:
Para manter a certicação do auto-falante, não tente restaurar a
cobertura à prova de fogo. As unidades cujas coberturas à prova
de fogo necessitem ser restauradas deverão ser enviadas à em-
presa “Federal Signal” para seu devido conserto.
O intervalo máximo do trajeto da chama para as variantes de ga-
ses IIB é o mesmo que para o grupo de gases IIC.
Todos os parafusos das terminais, estejam as mesmas em uso ou
não, deverão ser apertados à pressão de 0,5 N • m a 0,7 N • m.

120 Series Loudspeakers and Sounder
Check label details to ensure the unit is of the correct electrical rat-
ing and hazardous area classication.
For permanently connected equipment located in safe areas, the
equipment supply should be provided via a disconnect device lo-
cated in close proximity to the equipment and within easy reach
of the operator, which is marked as the disconnecting device for
the equipment.
For permanently connected equipment located in a hazardous
area, the equipment supply should be provided via a disconnect
device located in a safe area or via a suitable ATEX approved dis-
connect device located inclose proximity to the equipment, which
is marked as the disconnecting device for the equipment.
Where the disconnect device takes the form of a circuit breaker it
must be properly sized for the required current. The wiring feed-
ing the equipment must be properly sized for the required current.
Recommended cable specication: Elastomeric insulated and
braided armored for xed wiring in ships and offshore units to
BS6883 or IEC92-3.
Maximum core size: 2.5 mm2
Recommended cable gland: Hawke 501/453/univ or equivalent

120 Series Loudspeakers and Sounder
Installing the Product
This product must be installed and maintained only by qualied per-
sonnel who have received the relevant training. During installation
ensure that all external screw threads and ameproof faces are suit-
ably greased. Recommended torque on all external xings is 5 N • m.
Check details on the label to ensure the unit is of the correct electrical
rating and hazardous area classication.
Ensure the unit is securely mounted using the supplied bracket. Use
M12 for the center hole and/or 2 x M6 in the outer holes (Figure 2).
You can adjust the angle of the loudspeaker by using the external
ratcheted brackets on each side of the body (Figure 3 on page 12).

Accessing the Terminals and Glands
To access the cable terminals remove the end cap by rst remov-
ing the four M5 socket-head cap screws (Figure 3 on page 12).
The M20 gland entry is located in the main enclosure. Ensure the
cable is terminated in accordance with the gland manufacturer’s
instructions using approved cable glands. Any unused entry must
be sealed with a suitably certied stopper plug.
NOTE: Loudspeakers in close proximity must be connected in the
same phase.
