Advanced Fire Detection for both Passenger and Technical Compartments.
Aspiration Smoke Detectors, Point Type Detectors (Smoke, Heat, and CO), and Linear Heat Detectors on RS-485 bus.
We can build systems that can run on an RS-485 vehicle and/or train bus, with a decentralized car architecture.
We can use both addressable detectors and also conventional sensors.
