D2xB1LD2-H UL1971 Haz Loc Đèn Led Đồng bộ hóa

D2xB1LD2-H được tự động đồng bộ hóa nhấp nhay và sáng được kiểm tra theo tiêu chuẩn UL1971 được áp dụng cho các hệ thống báo cháy, ADA cho người khiếm thị. Các tiêu chuẩn được chứng nhận UL/cUL cho Class I Div 2, Class II Div 2, Class I Zone 2/22, IECEx và ATEX cho Zone 2 và 22 áp dụng cho các khi vực nguy hiểm.

The D2x1BLD2-H utilizes an array of high power Cree® LED's, orientated to optimize visibility in any direction. Multiple D2xB1LD2-H units will auto-synchronize when powered from the same power source removing the need for any additional sync modules on the circuit. The D2xB1LD2-H contains a supervisory diode and duplicated pluggable terminals that not only simplify installation but also enable a 4 wire connection. UL1971 effective candela rating of 38.38cd.
