Bosch LH2-UC15E loudspeaker Grey Wired 15 W

The Horn Loudspeaker LH2‑UC15E is specifically designed for excellent sound reproduction in marine applications (meeting standards such as IEC 60068-2-11) 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 plastic (ABS). The horn is standard supplied with a stainless steel mounting bracket.

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. For enabling loudspeaker supervision, a wire loop from the secondary side of the horn loudspeaker is available in the connection area. This wire loop is normally closed, but when used with the supervision board, it is cut and connected.
