1.11.010 Intrinsic safety: Visual The IS-mB1 is a compact beacon with an array of six high output L.E.D’s. Approvals include ATEX, IECEx and GOST-R for Zone 0 applications and FM approval for Class I Division 1 and Class I Zone 0 applications. The IS-mB1 is suitable for all intrinsically safe signalling applications including re, security and process control. Light source: Specication: Array of 6 high intensity L.E.D’s.
