Apollo XP95A Open Area Sounder – White (55000-042USA)
The Apollo XP95A Open Area Sounder (55000-042USA) delivers powerful audible alarm note for use in open area fire alarm applications. Designed for compatibility with Apollo Discovery UL and XP95A fire alarm systems, the sounder provides reliable warning signals while offering advanced monitoring and addressing capabilities.
Powered directly from the detection loop, the 55000-042USA eliminates the need for a separate power supply, helping to simplify installation and reduce wiring requirements. The sounder communicates with the fire alarm control panel, allowing the system to monitor device status and identify faults quickly.
The unit offers two selectable sound output levels of 92 dB(A) and 100 dB(A), enabling installers to match the alarm volume to the application. In addition, tone harmony ensures multiple sounders operate together, creating a clear and consistent alarm signal throughout the protected area.
Furthermore, the sounder supports both individual and group addressing, providing flexibility when setting alarm zones and disaster response strategies. A built in short circuit isolator helps maintain loop integrity by isolating faults and allowing the remainder of the system to continue operating.
