The STExS1R is a high output, 115dB(A) alarm horn sounder with a re-entrant flare horn. Low current consumption and high SPL in a robust IP66 corrosion proof 316L stainless steel enclosure ensure the STExS1R 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.
