Description
The Apollo 45681-331APO XP95 Sounder Visual Indicator Base is a combined addressable sounder and red flashing beacon, engineered for high-performance fire alarm notification in indoor applications. Loop-powered and fully compatible with XP95, Discovery, and CoreProtocol systems, this unit ensures seamless integration into existing fire alarm loops.
Designed with two selectable sound output ranges (55–75dB(A) for low-alert environments like hospitals and 75–91dB(A) for general applications), it supports both individual and group addressing. The integrated visual indicator flashes once per second and synchronises perfectly with alert and evacuate tones to ensure consistent and unmistakable signalling.
Self-test diagnostics for both acoustic and visual outputs reduce maintenance overheads by automatically detecting faults. Additionally, the built-in isolator eliminates the need for separate isolation devices, saving time and installation costs.
Compliant with EN54 standards and housed in a robust polycarbonate casing, this sounder VID base delivers trusted performance in a compact, efficient package.
