Apollo Multi-Tone Open-Area Sounder Visual Indicator with Isolator – White (55000-294APO)
The Apollo 55000-294APO Multi-Tone Open-Area Sounder Visual Indicator combines powerful audible and visual alarm notification in a single addressable device, making it ideal for indoor open-area fire alarm applications. Designed for use with Apollo XP95 and Discovery fire alarm systems, it provides clear warning signals while simplifying installation and system integration.
The device combines a high-performance sounder with a visual indicator to ensure alarms can be both heard and seen. In addition, it complements Apollo’s range of Intelligent Base Sounders, Integrated Base Sounders, and Multi-Tone Open-Area Sounders, enabling a consistent signalling solution throughout a fire detection system.
The 55000-294APO offers a choice of industry-recognised alarm tones, including Apollo, Slow Whoop, and DIN tones. Users can also select between 92 dB(A) and 100 dB(A) output levels to suit the installation environment.
Furthermore, the sounder supports synchronisation of Alert and Evacuate tones, ensuring consistent alarm operation across multiple devices. Individual and group addressing provides additional flexibility, while the built-in short-circuit isolator helps maintain loop integrity and system availability in the event of a wiring fault.
