u Suitable for marine and industrial applications in
humidity-, chlorine- and salty environments
The compact Horn Loudspeaker LH2‑UC06 is
specifically designed for excellent sound reproduction
in marine applications and other industrial
environments.
The units are rugged, water- and dust-protected, and
resistant to the corrosive effects of seawater and most
industrial atmospheres.
The horn loudspeaker is made from a high impact ABS
material. This strong, fire-retardant and corrosion
resistant material is chemical resistant and thermally
stable, making it ideal for even the harshest
environments. The horn is standard supplied with
corrosion resistant ABS mounting bracket.
Functions
u Tough, high impact ABS material with UL94 V0
fire‑retardant properties
u Water– and dust‑protected to class IP 67
u Type approval certified EN 60945
(4.33”) in a wall or ceiling by means of 4 screws (not
standard supplied). In this case, the bracket is
removed and 4 marked holes – at the rear of the horn
rim – needs to be drilled.
The horn loudspeaker is standard supplied with a
sturdy ABS mounting bracket allowing the sound beam
to be accurately directed.
The horn loudspeaker is supplied with a 1 m
color‑coded 6‑core cable, with each color connected
to a different primary tap on the matching
transformer. This makes it easy to select nominal
full‑power, half‑power, quarter‑power or eight‑power
radiation (i.e. in 3 dB steps) without opening the unit
during installation. The horn loudspeaker can be
optionally flush mounted in a diameter hole of 110 mm
