D1xB2XH2 UL1971 Auto Sync Explosion Proof 190cd Strobe

The D1xB2XH2 is the brightest explosion proof Xenon Strobe light/beacon available for public mode fire alarm, ADA compliant, hearing impaired applications. The unit is UL/cUL approved for Class I Div 1, Class II Div 2, Class I Zone 1 suitable for both gas and dust environments.

The lightweight, marine grade, enclosure has been designed to create the optimal fire signal. Its innovative construction includes both conduit or surface mounting capabilities - without the need for any additional accessories. For complete flexibility an optional stainless-steel bracket enables the light to be rotated and positioned in any orientation.
Multiple D1xB2XH2 units will auto-synchronize when powered from the same power source; removing the need for any additional sync modules on the circuit.
