New & Upgraded Alarm Horn Sounders- GNExS & STExS

New & Upgraded Alarm Horn Sounders – GNExS & STExS


E2S Warning Signals are pleased to announce new products and significant upgrades to the GNExS and STExS explosion proof alarm horn sounder ranges and the STExC1 combined sounder with Xenon beacon.

NEW PRODUCTS: For applications requiring the maximum audible warning effectiveness E2S have now launched the GNExS2H and STExS2H high output alarm horn sounders. With a maximum sound pressure level output of 127dB(A) at 1 metre (118dB(A) at 10 feet) the new ‘2H’ super high output flare horn design ensures unparalleled levels of audibility in hazardous locations.

UPGRADES: All GNExS and STExS units have been upgraded and now feature new electronics utilising the latest in D class amplifier technology providing improved sound output levels, in-rush control and a full range volume control. Now tropicalised as standard ensuring suitability for the harshest of environments.

  • GNExS1F and STExS1F short flare horn product versions producing up to 115dB(A) SPL with a maximum current consumption of only 221mA.
  • GNExS1R and STExS1R radial horn versions are compact sounders with an SPL of up to 113dB(A) and providing an omnidirectional sound dispersion.
  • GNExS2F and STExS2F long flare versions now feature two user selectable power modes enabling a choice of the standard 120dB(A) SPL or the high output setting creating a 123dB(A) alarm.

The 64 alarm tones include internationally recognised frequencies and patterns and the first and second stages can be selected independently of each other. For non-standard alarm tones and alarm stage configurations, E2S provide customisation to meet specific requirements.
The four alarm stages/channels can be remotely activated via common positive or negative switching. New cabling configurations permit both reverse and standard polarity line monitoring across multiple alarm stages. Additionally, the four of the alarm stages can be activated and line monitored via independent outputs – ideal for use with PLC based systems employing line monitoring modules on each channel.

All mounting brackets, plus the beacon guards on the combination signal STExC1, are now A4 316 Stainless Steel as standard.
The GNExS and STExS alarm horn sounder ranges provide robust solutions for life safety notification in the harshest of environments. The GNEx range employs an enclosure manufactured from corrosion free GRP (glass reinforced polyester) and is approved to IECEx, ATEX, Ex EAC and INMETRO for all Zone 1 applications. The STEx range features a 316L stainless steel enclosure and is IECEx, ATEX, Ex EAC, INMETRO and DNV approved for Zone 1, 2, 21 & 22 explosion proof signalling applications. Both ranges are SIL1 compliant to IEC 61508.
