Pfannenberg will showcase industrial fire alarm signaling solutions at the 2026 National Fire Protection Association (NFPA) Conference & Expo.
The company announced it will highlight products and application expertise at the Mandalay Convention Center in Las Vegas from June 22-24.
Engineers and facility teams can use these tools to build fire alarm systems for complex industrial environments.
Jacob Vernon, Product Manager for Audible and Visual Signaling at Pfannenberg, said: “As industrial environments become louder and more complex, the need for clear, code-compliant alarm coverage continues to grow.
“Through our PATROL, PYRA, and PROTECT product families, along with tools that make selection easier and more precise, we enable engineers to design reliable, standards-aligned fire alarm systems for harsh industrial settings.”
Pfannenberg fire alarm solutions support performance-based coverage for both public and private mode applications.
These devices comply with NFPA 72 requirements through specific acoustic performance.
The T3 tone in the sounders meets offset requirements of 10 dB for Private Mode and 15 dB for Public Mode.
Both the PATROL and PYRA product ranges are UL listed and fully compliant with NFPA 72 standards.
Pfannenberg sizing requirements exceed the minimum requirements found in NFPA 72 performance-based alternatives.
Products integrate with Building Information Modeling (BIM) software and proprietary 3D coverage tools to support alarm planning.
The PATROL line of audible and combination devices provides adjustable sound output ranging from 85 to 122 dB(A) for high ambient noise levels.
Visual signaling for industrial notification is provided by the PYRA line which offers flexible installation options.
The PROTECT Series features audible and combination devices housed in die-cast aluminum for hazardous and explosive environments.
These devices include 80 selectable tones and four externally selectable additional tones.
Pre-alarm and main-alarm functionality is included to reduce shock reactions among personnel.
Select models carry SIL 2 certification and are certified for Class 1 Division 2 hazardous locations.
The company offers a 10-year warranty across key signaling lines for applications including battery energy storage systems.
