BExCS110-L2 Omni-directional Alarm Horn & LED Beacon

The flameproof BExCS110-L2-R combination omni-directional alarm horn sounder and high output LED beacon is suitable for Zone 1, 2, 21 & 22 applications. Approved to IECEx and ATEX standards.

The unique radial horn on the compact BExCS110-L2-R distributes the audible warning signal omni-directionally allowing the visual signal to be orientated optimally. Sound level ouputs are up to 115dB(A) at 1 metre with a choice of 32 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. DC voltage versions feature three remotely selectable stages enabling multiple warnings to be signalled from one device.
