Apollo Discovery Base Sounder Visual Indicator Red Flash

Reliable Dual Alert Technology for Intelligent Fire Detection Systems

The Apollo Discovery Base Sounder Visual Indicator (Red Flash) is a sophisticated addressable fire alarm component that provides both audible and visual alerts in one compact unit. Designed for seamless integration into Discovery and XP95 protocol systems, this device delivers dependable performance and flexibility for a wide variety of environments—from commercial offices to healthcare facilities, educational institutions, and public buildings.

Ideal for applications that require high-impact visual warnings, the red flash ensures clear visibility during alarms, especially in areas where hearing protection is used or ambient noise levels are high. This loop-powered unit offers a combination of intelligent control, wide configurability, and simple on-site adjustment, making it a trusted solution for modern fire detection installations.

Compact and Versatile Installation

The Discovery Base Sounder Visual Indicator is designed to be mounted directly onto either an XPERT 7 or XPERT 8 base, allowing for quick and easy installation with minimal disruption. Using the SA5000-20X XPERT 8 Base, installers also benefit from an integrated Short Circuit Isolator (SCI), which protects the loop against wiring faults without compromising overall system integrity.

For applications where no detector is required, a range of base caps is available (sold separately), allowing the sounder and visual indicator to be used as a standalone signalling device.

Flexible Tone and Volume Configuration

A key feature of the Apollo Discovery Base Sounder Visual Indicator is its range of 15 evacuation tone pairs, including the familiar Apollo evacuation tone. These tones can be configured during commissioning to match local regulations or to reflect specific operational needs within a facility. Each tone also has a secondary alert tone, ideal for pre-alarm warnings or staged evacuation procedures. To accommodate different environments and acoustic conditions, the sounder supports seven volume settings, with output levels ranging up to 95 dB(A) at 1 metre. This adjustability ensures effective coverage while minimising noise disturbance, particularly in quiet or sensitive areas.

Easy On-Site Setup and Testing

Commissioning is made even simpler thanks to the device’s ability to be configured on-site at the device location. Using a magnetic wand, engineers can walk from device to device to set individual volume levels, which are then saved collectively on the control panel. This streamlines the process of system setup and fine-tuning, saving both time and resources. Additionally, the unit includes a unique acoustic self-test function, allowing the sound output to be verified without triggering the full fire alarm system—an invaluable feature during maintenance checks.

Dual Control and System Integration

This model supports independent control of the sounder and visual indicator, enabling tailored signalling strategies based on the requirements of each installation zone. The unit communicates over the loop using Apollo’s Discovery and CoreProtocol® digital systems, providing features such as group, global and individual device control, as well as real-time status reporting. Such intelligent configurability ensures that the sounder and visual indicator respond precisely as intended during fire events, contributing to the overall safety and efficiency of the alarm system.

Compliance and Build Quality

The Discovery Base Sounder Visual Indicator is manufactured to comply with the EMC Directive 2014/30/EU and the Construction Products Regulation (EU) 305/2011. It meets all necessary performance and durability standards for use in regulated fire safety systems and is constructed from high-grade, flame-resistant materials. A full Declaration of Conformity is available via the Apollo Fire Detectors website.
