Loa Chống cháy nổ GNExS2 BExH120 Alarm Horn Sounder 123dB(A) E2S Vietn, STC Vietnam
STExS2F Alarm Horn Sounder
The STExS2F is a high output, 123dB(A) alarm horn sounder 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.
