Bulletin 855R Industrial Beacons


The Bulletin 855R industrial beacons improve how industrial operators deliver warning and status indications to workers on the plant floor. The family of 110 mm industrial round beacons offers enhanced performance compared to other beacon lines and can meet a broader range of signaling needs.


A single Bulletin 855R beacon can offer both audible and visual indication, helping to prevent confusion on the plant floor in the event of a critical machine or equipment condition alert. With multiple light-pattern options and multiple mounting options, the beacons can be used for a diverse mix of signaling applications.


The use of maintenance-free LED technology and using one beacon family to signal up to three machine or equipment conditions reduces costs. Other functionalities include the ability to provide up to 15 DIP switch selectable light patterns in groups of seven, multicolor functionality, two profile options, high-brightness functionality, and an audible mounting base that’s compatible with all LED beacon modules.


All 855R devices are available in 24V DC, 120V AC, or 240V AC global ratings. The 855R product family is certified to meet cULus, CE, KCC, RCM, UKCA, and Morocco requirements for global applications. A high IP66/67 and UL Type 4/4X/13 ingress protection rating makes the product family suitable for indoor or outdoor industrial signaling applications.
