The Apollo 45681-330APO Sounder Visual Indicator Base is a loop-powered unit that combines an audible sounder and visual indicator with a standard Intelligent Mounting Base.
Part of the Apollo fire detection range, this device is compatible with XP95 and Discovery protocols, making it ideal for integration into new or existing Apollo addressable fire alarm systems.
It provides both audible and visual fire alarm signalling, ensuring clear alerts in enclosed areas such as offices, schools, healthcare facilities and retail spaces.
For applications where the device is needed as a standalone sounder or beacon without a detector fitted, an optional cover cap is available.
