SB125 — Explosion Proof Stainless Steel Sounder Beacon
The SB125 is a flameproof sounder beacon combination for potentially explosive atmospheres. ATEX and IECEx certified for gas and dust zones and SIL2 compliant, it pairs a high-output horn sounder with up to four beacons on a single 316L stainless steel backplate.
Each unit uses a 316L stainless steel housing with a UV-resistant coating with a borosilicate glass lens, optionally protected by a 316L stainless steel guard. Up to three tones can be selected from 59 preloaded options with external switch pause control, and the sounder and beacons can be triggered jointly or independently. One beacon can be replaced by a push button or junction box. Ambient range is −40°C to +70°C.
For a GRP enclosure, see the SB150.
Typical applications: oil and gas, petrochemical, chemical plants, offshore platforms, marine, refineries.
