Explosion Proof Xenon Strobe Beacon 21J

Description

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 from 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.
