The BRS is a repeater type signal used to provide a train driver advance notification of the state of the next colour light signal. The signal is derived from displaying a black bar on a circular white background. This signal has 2 states; a diagonal bar and a horizontal bar. Where a third aspect is required, this is achieved from a diagonal black bar on a circular green background.
Designed with consideration to RT/E/S10062 (Long Range CLS) and BR1651pt3 (Fibre Optic Banner Signal).
Features and benefits
- Long life LED light source
- Clear and distinct "black bar"
- 2-state: white horizontal and diagonal aspects
- 3-state: white horizontal and diagonal aspects, green diagonal aspects
- Wide angle viewing
- Backwards compatibility with existing signals
- Auto regulating from 78V to 131V AC
- No external hoods - construction provides phantom immunity
- Each aspect is electrically independent
- Non-corrosive materials used throughout
- Only 110mm thick and weighing 20Kg - requires less substantial infrastructure
- "Plug & Play"; speedy connection / disconnection
- No-maintenance Line Replaceable Unit
- Easily retrofitable
The banner signal weighs only 20kg and measures 110mm thick.
