Large rooms and high ceilings

The Siemens FDL242 provides fire protection for large areas with high ceilings up to 120 meters. Its seamless integration into Siemens fire systems guarantees reliable detection, enabling uninterrupted operations. The detector simplifies installation with laser-assisted, motorized self-alignment and minimizes false alarms with light and soiling compensation algorithms.
The Siemens FDL242 light beam smoke detector helps you protect valuable spaces such as:
The FDL242 seamlessly integrates into Siemens fire systems, compatible with Sinteso and Cerberus panels. It's loop-powered with an integrated line separator for 24/7 reliability, and offers cloud access for event and soiling data.
One-person installation is fast and easy with laser-assisted reflector mounting and motorized self-alignment. The integrated UI enables efficient operation without extra tools, and opposing detectors work interference-free.
The detector features an integrated user interface and 6 EN 54-12 approved parameter sets for diverse applications. With the Building X Fire Connect app, a single individual can effortlessly perform all necessary tests.
The linear beam detector FDL242 uses light compensation algorithms that adjust for changes in ambient light levels. This feature helps to minimize false alarms triggered by direct sunlight or artificial light sources.
The detector’s infrared beam maintains a constant signal level, even in the presence of dust. This feature not only extends the lifespan but also improves performance and allows for longer maintenance cycles.
The system guarantees accurate alignment of the detector and reflector along the optical beam path — meaning you won't need to manually adjust for building movement due to temperature changes.
An integrated isolator increases safety by preventing the propagation of electrical faults. It removes the need for separate isolation modules, which results in a more streamlined system design.
