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 classied as
Zone 1 with a temperature classication 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 certication 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 components 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 specic 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 surfaces are nished in powder coat paint and external hardware is manufactured from stainless steel to resist corrosion.
