System Sensor LENS-B3 L-Series Indoor WallCeiling Mount Strobe, LED Lens, Blue

Enhance your emergency communication and mass notification systems with the System Sensor LENS-B3 blue LED strobe lens. This L-Series lens converts compatible wall- or ceiling-mounted strobes into bright, color-coded visual alerts—ideal for security, surveillance, monitoring and noisy environments where audible alarms may be missed. The blue LENS-B3 is engineered for simple, snap-on installation to L-Series LED strobes (part number LENS-B3, L-Series), enabling quick retrofit or expansion without rewiring. Intended for indoor use on non-fire-printed devices, the lens supports both ceiling and wall mount applications to suit a variety of facility layouts. By adding a dedicated visual indicator, you can improve situational awareness, accelerate response times during ECS/MNS events, and maintain a professional, integrated emergency lighting strategy. Add the System Sensor blue strobe lens to your security or emergency lighting plan to boost visibility and compliance—order or contact us to integrate color-coded alerts into your next project.
