Universal Emergency Mushroom Button
PB55B-SO is a high-visibility illuminated emergency push button designed for instant assistance signaling in restroom, access control, and public safety applications.
Its large red mushroom actuator and high-brightness LED illumination provide clear visibility even under bright ambient lighting, while the weather- and vandal-resistant construction ensures reliable performance in demanding environments.
When not illuminated, the button remains visually neutral, blending seamlessly with modern architectural finishes. The unit operates on field-selectable 12/24V DC power and includes an adjustable 85 dB piezo sounder for immediate audible confirmation.
