Combination Radial Horn & LED


The unique radial horn on the compact E2xC1LD2R distributes the audible warning signal omni-directionally allowing the visual signal to be orientated optimally. The alarm horn offers a choice of 45 alarm tones and 3 remotely selectable stages. The LED beacon contains an array of 4 high output, multi-function L.E.D.s. with a total of 7 modes of operation – 5 flashing modes and 2 steady modes for use in indicator / status applications. The E2x range features enclosures manufactured from lightweight, corrosion proof GRP and high impact, fire retardant ABS re-entrant flare horns; both of which are suitable for the harshest of environments.
