The D1xB2X21 is a globally approved explosion proof 21 Joule Xenon beacon.
The robust IP66, Type 4/4X corrosion proof LM6 marine grade aluminium
alloy enclosure ensures suitability for all Class I/II Div 1, Zone 1, 2, 21 & 22
applications.
Approved to UL1638 and CAN/ULC S526 for fire alarm use the D1xB2X21 beacons produce a high
output Xenon flash required for effective signalling in environments with elevated levels of ambient
light. The field replaceable colour filter enhances the strobe and is constructed fr m UV stable PC.
The robust enclosure features a threaded flame path, four cable entries. Mounting options include
surface via integrated lugs, pendant or by addition of optional multi direction stainless steel
bracket. SIL1 compliant to IEC61508 (2010) as standard – SIL2 version available.
