E2S STExS2 Explosion Proof Sounders

 

E2S STExS2 Explosion Proof Sounders for Hazardous Area Signalling Applications

The STExS2F are high output 123dB(A) alarm horn Explosion Proof Sounders with a re-entrant flare horn. The robust IP66 corrosion proof 316L stainless steel enclosure ensures the STExS2F is suitable for all Zone 1, 2, 21 & 22 explosion proof signalling applications. Featuring 64 first stage/channel alarm sounds which can be selected via an internal switch. The alarm tone frequencies for the first 2 stages are independently selectable. Each tone can be remotely triggered e.g. via an external relay, to change to a second, third or fourth stage/channel alarm sound. The enclosure features a threaded flame path, triple cable entries and a large termination area – all of which significantly reduce installation time.
