April 28, 2015 – The E2x series of non-sparking alarm horn sounders, Xenon strobe beacons and combined devices from E2S have gained approval for Zone 2, 22 applications to the latest IECEx and ATEX standards for gas and dust applications, says E2S. These approvals complement its existing Class I & II Division 2 UL and cULs approvals.

The main enclosure of the E2x is manufactured from corrosion-proof PPS, and the re-entrant horns from high impact, fire retardant ABS, E2S said. Selected models are available with the 360° radial horn option.
 
The series consists of 45 tone, three channel/stage electronic alarm horn sounders with an output of up to 121dB(A) @ 1 metre (112dB(A) @ 10ft/3m). E2x visual signals include Xenon strobe 5 and 10 Joule beacons, available with a choice of six lens colours and provide up to 1,000,000 peak candela. Combination signals offer a SPL of 116dB(A) @ 1 metre (107dB(A) @ 10ft/3m) with a 5 Joule Xenon strobe. For PA applications the E2x loudspeakers are available as 15 or 25W in either line transformer or low impedance versions.
 
Operating voltages include 12, 24 or 48Vdc and 115 or 230Vac. Dual cable entries, either M20x1.5 or ½ in. NPT (or a combination of both sizes) facilitate easy installation and in-out wiring configurations, E2S said.
