Vital Relay PSD, platform screens with safety relays

Vital Relay PSD systems are landing doors fitted with a control system based on safety relays, a tried-and-tested technology that has been in use for over 30 years in the first generations of landing doors. Renowned for its reliability and robustness, this architecture meets the safety and availability requirements of railway infrastructure.

The installation of automated platform screen doors (PSDs) is now an essential solution for supporting the development of rail transport networks. By creating a secure barrier between passengers and the tracks, they help to improve safety for passengers and staff, whilst optimising the operation of the lines.

PSD Vital Relay systems address the key challenges facing railway stations and rail networks:

to improve the safety of passengers and operational staff;
to improve the management of train flows and the punctuality of services;
to optimise the energy performance of interior spaces;
improve the thermal and acoustic insulation of the platforms;
to improve user comfort;
to enhance the appeal of transport infrastructure;
to streamline passenger flows when boarding and alighting.

Custom made, full-height platform screen doors

To best address these challenges, we offer a range of bespoke loading bay doors, which can be fully customised to suit the specific environmental and operational requirements.

Technical specifications

Resistance to a crowd-load of 3,000 N/m applied 1,100 mm above the floor, in accordance with NF P 01-013.
Impact resistance of 700 J using a standard M50 bag (50 kg of tempered glass beads) in accordance with NF P08-301.

Lifespan: 30 years and over.
Temperature: between -25 °C and 55 °C (adjustable as required).
Relative humidity: 5% to 90%.
Electromagnetic compatibility: in accordance with EN 50121-4, EN 61000-6-2 and EN 61000-6-4. The front panel does not block the transmission of radio waves (e.g. no interference with 4G).
Floor and ceiling fixings.
Door leaf with a self-supporting four-sided frame.
Frame: aluminium / steel.
Adjustable width and height of the opening.
Glazing: glass class 1-B-1 in accordance with EN 12600.

Opening speed: 2 seconds per door (adjustable).
Closing speed: 2.5 seconds per door (adjustable).
Maximum closing force: 450 N.
Maximum closing energy: 20 J.
The doors must open in synchronisation with the underground doors.
Low-voltage or extra-low-voltage power supply to the façade (230 V or 48 V AC).
Reporting of door status (closed, locked, fault, etc.) to the monitoring system (and SCADA).

NB: The opening and closing speeds are not set to their maximum performance levels for obvious safety reasons. The speed curves can be adjusted to ensure smooth movement in line with the opening rate of underground station doors. Their speed is determined by the weight of the door leaves and the 20-joule limit.

Recessed walkway lighting that can be disconnected.
Advertising or information screens.
Advertising screens and/or passenger information displays in swing doors.
Advertising screens and/or passenger information displays in the transom.

Other options:

VEC glazing or glazing with glazing beads.
Marking and screen-printing on glass.
RAL colours for aluminium profiles.
High-performance RILSAN insulating coating.
