A system as individual as you are.
A Bosch fire alarm system provides you with the opportunity to retain the value of your equipment, as all new systems designed by Bosch interface with previously installed systems. From reliable fire detection to advanced voice evacuation, Bosch delivers a safe, futureproof investment for any kind of location. In a technologydriven world, Bosch offers you exactly what you need.
Reliable – Bosch offers a broad portfolio of EN- and UL-certified products* and systems for accurate, reliable fire detection and notification. Our solutions provide precise, life-saving information at critical moments – you can count on us.
Flexible – Bosch gives you the opportunity to configure your own system according to your specific needs based on the modular principle. The system adapts to the nature and size of your facility’s application, so you are provided with flexibility in your buying decisions.
Customer-specific – Bosch offers you the unique software development kit (SDK) suite, containing all the tools to design customer-specific fire safety management systems and software modifications.

All you need to detect, report and visualize a fire
Special detectors – In buildings that do not allow the installation of point-type detectors, e.g. linear heat detectors, aspirating smoke systems, flame detectors and beam detectors provide customized protection.
Manual call points – Our range includes single-action and doubleaction manual call points which can be employed in our addressable LocalSecurityNetwork (LSN) as well as in conventional technology. Both large and small design types are available for different applications.
Interface modules – Input, output or combined high- and low-voltage relays for the controlled activation of a group of signaling devices and for the connection of conventional peripherals: The interface modules in the 420 Series have been specifically developed for connecting to the LocalSecurityNetwork improved version, which will help you optimize your fire detection scenario.
The 500 Series is totally different, because it uses a virtual optical chamber. It is ultra-slim and lies flush with the ceiling – a distinct advantage which does not detract from the appearance of attractive rooms. Color rings that can be mounted in the detector also allow the units to be perfectly coordinated with the color of the surrounding ceiling.
Discreet styling outside, Bosch know-how inside: The 500 Series has style built in. Inside it is packed full of proven know-how from Bosch. And that is something you can rely on. The unique technological approach ensures that you have made the right investment for the future.
Powerful technology: The 500 Series is a scattered-light fire detection system with a dual detection area. Because the sensors monitor two independent light areas in open space, the detector is extremely reliable. The invisible detector is also available as a multi-sensor detector with a carbon monoxide (CO) gas sensor. This combination of scattered-light sensor and CO gas sensor allows alarms to be evaluated using intelligent signal processing methods. This greatly decreases the likelihood of false alarms and increases the number of possible applications since this detector even works well in environments that are unsuitable for standard photoelectric detectors
Award collection – not dust collection: The fact that there is a virtual optical chamber inside the Smoke Detector 500 Series means that it does not stick out of the ceiling. The smooth surface does not gather the usual visible dirt in rooms with high dust build-up. So it offers high reliability and it is easy to clean. On top of that, it saves service time and costs. The level of dirt build-up is continuously measured. A trouble signal indicates when a unit needs to be cleaned.
Giving architects more freedom: The low mounting profile of the 500 Series makes it invisible on any ceiling. The unique mounting method blends in easily with decor, allowing architects to focus even more on design and the general appearance.
