Description

Bosch LH2-UC15E 15W Marine Horn Loudspeaker

The Horn Loudspeaker LH2-UC15E is specifically designed for excellent sound reproduction in marine applications and other industrial environments. The housing is rugged, water- and dust-protected, and resistant to the corrosive effects of seawater and most industrial atmospheres. The horn loudspeaker is made from an UV-stable, glass reinforced polyester (GRP). 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 a stainless steel mounting bracket.

Key features:

  • Suitable for marine and industrial applications in humidity-, chlorine- and salty environments
  • Glass reinforced polyester housing with fire-retardant properties
  • Water"“ and dust-protected to class IP67
  • Provisions for internal mounting of the optional supervision boards
  • Type approval certified EN 60945 and EN54-24 certified
Functions

The horn loudspeaker is standard supplied with a sturdy mounting bracket allowing the sound beam to be accurately directed. The mounting bracket has a ratchet facility to ensure it stays correctly positioned. The connection cable is fed out through an ABS cable gland (PG13.5 standard supplied) in the rear cover, which can be removed for entering the inside connection terminal. For loop-through connection, the rear cover is fitted with a second hole (covered with a blanking plug as standard supplied). The horn loudspeaker includes a transformer for both 70 V and 100 V input voltage, with taps on the primary winding for different power settings. Nominal full-power, half-power, quarter-power or eight-power radiation (i.e. in 3 dB steps) can easily be selected by connecting to the appropriate terminal of the 6-way screw terminal block. The horn loudspeaker has built-in protection to ensure that, in the event of a fire, damage to the loudspeaker does not result in failure of the circuit to which it is connected. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation. The horn loudspeaker has ceramic screw-terminal connection blocks, thermal fuse, heat-resistant high temperature wiring and has a provision for internal mounting of the optional line/loudspeaker supervision boards.
