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.
