The LH3-UC25XL horn loudspeaker is specifically designed and certified for installations where explosive gas-air mixtures are likely to be present. The horn is constructed from anti-static Polyamid material, making the horn sturdy and light weighted. The longer flare design of the horn results in a higher sound pressure level where longer distance areas can be covered.
Functions
The horn loudspeaker is standard supplied with a sturdy stainless steel 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 EX cable gland (M20) in the rear cover, which can be removed for entering the inside connection terminal block. 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 100 V input voltage, with taps on the primary winding for different power settings. The different power taps can easily be selected by connecting to the appropriate terminal of the 6-way terminal block.
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 if used with the supervision board, cut and connected.
