ESP MAGPRO-DBSS Addressable Sounder Strobe Base – White | MAGfire Fire Alarm System

Intelligent Addressable Fire Alarm Detector Base with Integrated Sounder and Red Strobe

The ESP MAGPRO-DBSS Addressable Sounder Strobe Base is a combined audible and visual fire alarm device designed for use with compatible ESP MAGPRO analogue addressable fire alarm systems.

Part of the ESP MAGfire range, the MAGPRO-DBSS incorporates an integrated electronic sounder and red flashing strobe, providing audible and visual fire alarm notification from a compact detector base.

Designed for professional fire alarm installations, the MAGPRO-DBSS combines detector mounting, audible warning and visual indication within a single unit.

The base is compatible with selected MAGPRO addressable fire detectors, including the MAGPRO-SD1 smoke detector, MAGPRO-HD1 heat detector and MAGPRO-HSD1 combined smoke and heat detector.

When connected to a compatible MAGPRO fire alarm control panel, the sounder and strobe can be controlled through the system's addressable communication protocol.

The unit offers 32 selectable alarm tones and two volume settings, allowing the sound output to be configured according to the requirements of the installation.

With an audible output ranging from approximately 82dB to 100dB at 1 metre, depending on the selected tone and volume setting, the MAGPRO-DBSS provides flexible audible fire alarm notification.

The integrated red strobe flashes at 1Hz, providing a visual indication when the device is activated.

Operating from a 15–32V DC addressable fire alarm loop, the MAGPRO-DBSS is powered directly by the compatible fire alarm system.

Its compact 103mm diameter x 33mm depth design and white finish make it suitable for discreet installation in commercial, educational and other appropriate indoor environments.

The device uses ESP's proprietary MAGPRO communication protocol and is designed specifically for compatible MAGPRO addressable fire alarm equipment.

Certified to EN54-3 as a fire alarm sounder, the ESP MAGPRO-DBSS provides a practical solution for installations requiring integrated audible and visual fire alarm notification.

Combined Addressable Sounder and Strobe

The ESP MAGPRO-DBSS combines two fire alarm notification functions within a single detector base.

Its integrated sounder provides an audible alarm signal, while the red strobe provides a flashing visual indication.

This combined design is useful in installations where both audible and visual alarm notification are required.

Benefits of Combined Sounder and Strobe Technology

• Audible and visual alarm indication
• Compact combined device
• Integrated detector mounting
• Reduces the need for separate devices in suitable locations
• Suitable for addressable fire alarm systems
• Convenient system configuration
• Practical for professional installations

Important: The red strobe provides visual alarm indication, but suitability for applications requiring a certified visual alarm device under EN54-23 must be assessed separately. EN54-3 certification alone does not establish EN54-23 compliance.

32 Selectable Fire Alarm Tones

The ESP MAGPRO-DBSS supports 32 different alarm tone types.

The selected tone is configured through a compatible MAGPRO fire alarm control panel.

This allows the device to be programmed according to the fire alarm system design.

Benefits of Multiple Alarm Tones

• 32 selectable sound patterns
• Flexible fire alarm configuration
• Suitable for different installation requirements
• Tone selection through the control panel
• Supports coordinated audible alarm signalling

The selected alarm tone should be consistent with the fire alarm system's approved design and commissioning requirements.

Adjustable Low and High Volume Settings

The ESP MAGPRO-DBSS features two selectable volume settings.

These allow the sound output to be configured according to the requirements of the protected area.

Low Volume Mode

Depending on the selected tone, the sound output is approximately 82–92dB at 1 metre.

High Volume Mode

Depending on the selected tone, the sound output is approximately 90–100dB at 1 metre.

Benefits of Adjustable Volume

• Two selectable sound levels
• Flexible system configuration
• Suitable for different room layouts
• Supports professional sound-level planning
• Configurable through a compatible fire alarm panel

Important: The required alarm sound pressure level must be determined through the fire alarm system design and commissioning process.

The number of sounder bases supported on a loop depends on the selected operating mode, panel capacity, loop loading and system configuration.

Integrated Red Strobe with 1Hz Flash Rate

The ESP MAGPRO-DBSS includes an integrated red flashing strobe.

The strobe operates at a frequency of 1Hz, providing one flash per second during activation.

Benefits of the Integrated Strobe

• Visual indication during alarm activation
• Red flashing light
• Combined with audible warning
• Compact integrated design
• Suitable for compatible addressable systems
• Helps identify an active alarm condition

The suitability of the visual indication for a particular installation should be assessed against the applicable fire alarm design requirements.

Compatible with ESP MAGPRO Addressable Detectors

The MAGPRO-DBSS is designed for use with compatible MAGPRO addressable detectors.

The detector mounts onto the sounder strobe base, allowing the two components to form a combined detector and alarm notification assembly.

Compatible Detectors

ESP MAGPRO-SD1

Addressable smoke detector.

ESP MAGPRO-HD1

Addressable heat detector.

ESP MAGPRO-HSD1

Addressable combined smoke and heat detector.

Benefits of Detector Compatibility

• Integrated detector mounting
• Suitable for MAGPRO addressable systems
• Combined detector and sounder arrangement
• Compact installation

Important: The MAGPRO-DBSS is a sounder strobe base, not a standalone smoke or heat detector.

A compatible detector must be selected separately where detection functionality is required.

Compatibility with newer detector variants should be confirmed against the relevant ESP technical documentation.

MAGPRO Analogue Addressable Communication

The ESP MAGPRO-DBSS operates using ESP's proprietary MAGPRO addressable communication protocol.

This allows a compatible fire alarm control panel to communicate with and control the device.

The sounder and strobe receive their operating instructions through the fire alarm system.
