Apollo Discovery Base Sounder Visual Indicator White Flash

Advanced Addressable Sounder with Integrated Visual Alert (White Flash)

The Apollo Discovery Base Sounder Visual Indicator (White Flash) is a feature-rich, addressable fire alarm device designed to deliver both audible and visual alerting from a single compact unit. Suitable for use in a wide range of commercial, industrial and public sector environments, this loop-powered sounder combines powerful performance with intelligent configurability. Its white flash output makes it particularly suitable for modern interiors or areas where a less intrusive visual signal is required.

Designed for seamless use with Apollo Discovery and XP95 protocols, the device supports flexible system integration and is compatible with XPERT 7 and XPERT 8 detector bases. With a wide selection of tones, volume levels and control features, the unit offers installers and commissioning engineers a reliable solution for creating tailored fire detection and evacuation strategies.

Dual Signalling for Comprehensive Coverage

The Discovery Base Sounder Visual Indicator is engineered to provide both audible and visual warnings, ensuring maximum visibility and intelligibility in an emergency. The white flash visual signal is particularly effective in bright environments or where the standard red flash is not desired. The sounder and visual indicator can be controlled independently, allowing for customised operation based on location, risk level or alert type. This flexibility makes the unit suitable for a wide range of applications, from open-plan offices and retail spaces to healthcare facilities, hospitality settings and educational institutions.

Multiple Tone and Volume Options

To accommodate different regulatory requirements and building types, the sounder offers a choice of 15 tone pairs, including the standard Apollo evacuation tone. Each tone pair includes a secondary alert tone, which can be used for warning occupants of a possible evacuation or to signal specific site events. The device also includes seven adjustable volume settings, with a maximum output of 95 dB(A) at 1 metre. Volume adjustments can be made on a device-by-device basis using a magnetic wand, with final settings stored centrally via the fire control panel. This approach ensures that each sounder is appropriately configured for its specific location, helping to maintain clarity without unnecessary noise intrusion.

Quick, Flexible Installation

The Discovery Base Sounder Visual Indicator is designed for simple, fast installation. It connects directly to Apollo's XPERT 8 or XPERT 7 base units, with no additional wiring required beyond standard loop connections. When installed using the SA5000-20X XPERT 8 Base (sold separately), the unit also features a built-in short circuit isolator (SCI), which enhances system integrity and allows for continued operation in the event of a wiring fault.

This ease of installation and modular design reduces labour time and makes the unit suitable for both new builds and system upgrades.

Smart Features and System Compatibility

Designed with system control and diagnostics in mind, the unit offers group, global and individual control functions, as well as status reporting, all configured via the fire control panel. The device supports Discovery and CoreProtocol® digital communication, ensuring it can be deployed across a wide variety of addressable Apollo systems. Installation and commissioning are further supported by a unique acoustic self-test function, allowing engineers to verify operation on-site without disrupting building occupants. Set-up can be completed at the device location, simplifying the commissioning process and ensuring accuracy across all devices in the system.

Standards and Compliance

The Apollo Discovery Base Sounder Visual Indicator (White Flash) complies with the EMC Directive 2014/30/EU and meets the requirements of the Construction Products Regulation (EU) 305/2011. It is built using high-grade, fire-resistant materials and has been tested for performance and durability in line with industry standards. Full documentation, including the Declaration of Conformity, is available from the Apollo Fire Detectors website.
