D2xB1XH1 Haz Loc UL1971 Xenon Strobe - Synchronized

The D2xB1XH1 features a high output UL1971 rated 18.18cd, 5 Joule Xenon strobe beacon. Low current consumption and in rush in a robust marine grade aluminum Type 4/4X, IP66 enclosure ensure the D2xB1XH1 is suitable for the harshest of haz loc environments. Multiple D2xB1XH1 units will auto-synchronize when powered from the same power source removing the need for any additional sync modules in the circuit.

One device, globally certified: NEC/CEC CI D2 and CII D2; NEC CI Zone 2 and Zone 22; CEC Zone 2 & 22 and CII D2; ATEX, IECEx Zone 2 & 22.
UL1638/UL1971 tested - suitable for public mode fire alarm, ADA compliant, hearing impaired applications.
