Fire protection solutions for the rail sector

In the rail sector, Diehl Aviation offers a globally unique fire protection solution. As an experienced system supplier, Diehl develops and delivers state-of-the-art, integrated fire protection systems tailored to the specific requirements of railway operations. This comprehensive solution combines precise detection, intelligent control, and effective fire suppression – all from a single source.

FIRE PROTECTION SOLUTION AT A GLANCE:

• Early detection via smoke detectors: Highly sensitive sensors detect smoke at the earliest stage of development.
• Central control through the Smoke Detection Control Unit (SDCU): Seamless integration into existing systems ensures rapid response and continuous monitoring.
• Efficient fire suppression with the Fire Fighting Module (FFM): A compact module designed for targeted extinguishing in emergency situations.
• Aerosol generators for fire containment: Innovative technology to effectively combat smoke and flames in confined spaces.

For more than 25 years, the company has been successfully active in this field. Diehl’s fire protection systems meet the high standards required in railway operations. Smoke development must be reported within fractions of a second, while false alarms must be minimized to avoid service interruptions and track closures. In addition, fires must be effectively, rapidly, and gently extinguished – both in passenger compartments and technical areas.

SYSTEM SUPPLIER FOR RAIL CUSTOMERS WORLDWIDE

Diehl Aviation is a technology leader in fire protection systems for the rail sector. As a reliable partner, the company supplies globally leading manufacturers such as Siemens and Alstom. All hardware and software development and production are carried out in-house – ensuring the highest standards of quality, innovation, and system safety.

KEY FEATURES

Maximum reliability:
Harmless aerosols from deodorants or insect sprays can easily be misinterpreted as smoke. Diehl Aviation’s smoke detectors reliably differentiate between these substances, effectively preventing false alarms.

Strong aviation synergy:
A current aviation standard requiring high resistance to false alarms onboard aircraft has been successfully transferred to the rail sector – a unique feature on the market.

Wide range of applications:
The Fire Fighting Module for active fire suppression can be used throughout the entire train. In passenger areas, a low-pressure water mist is applied, while nitrogen is used for dry suppression in moisture-sensitive technical systems.

High flexibility:
Diehl Aviation’s fire protection solutions are suitable for all types of trains – from high-speed trains to subways and trams. Whether as a complete system or as a stand-alone detector solution, the modular setup ensures ideal adaptation to customer needs.

Excellent cost-efficiency:
With over 25 years of proven operational experience, the systems offer low life-cycle costs for end customers. The smoke detectors are easy to maintain and clean. Diagnostic and maintenance data is provided via the SDCU through various train communication interfaces (CAN-open, Ethernet, relay).

Certification and safety standards:
Diehl Aviation’s fire protection systems comply with all relevant quality and safety standards.

QUALITY, SAFETY, AND RESPONSIBILITY IN RAILWAY TECHNOLOGY

Diehl Aviation develops systems and components for the rail sector that meet the highest standards of safety, reliability, and environmental sustainability. Whether for new vehicles or retrofit solutions, the company’s products stand for certified quality, standards-compliant implementation, and long-term performance in rail operations.

Safety systems for rail transport
Diehl Aviation’s hardware and software solutions meet the safety-relevant requirements of EN 50716 and EN 50129 (SIL 2). This makes them suitable for use in critical applications with high safety demands – a key aspect of modern railway technology.

Protection against cyber threats
To guard against digital attacks, Diehl Aviation integrates cybersecurity measures in accordance with IEC 62443 (SL1) and CLC/TS 50701. The security concept is further enhanced by digital signatures and user authentication to ensure the long-term integrity and safety of the systems.

Environmentally responsible product solutions
Diehl Aviation develops its products in compliance with internationally recognized environmental and health standards such as UNIFE RISL, REACH, and RoHS. This ensures that material selection and processes prioritize environmental sustainability and health protection. In addition, the company meets the requirements of EN 45545-2 for fire protection in rail applications.

Durability and robustness under real-world conditions
To ensure reliable performance even in harsh environmental conditions, Diehl Aviation qualifies its products according to EN 50155 and IEC 60571. This guarantees that systems remain stable and efficient throughout their lifecycle – even under temperature fluctuations, vibrations, and humidity.
