2.4.E.  OPTIONS FOR POWER SUPPLIES AND REINFORCED
LED SIGNS
To avoid power supplies or signs providing energy in vain and/or to
attract the attention of motorists, they can be paired with one or more
of the options below:
Daily, weekly or yearly clock:
Makes it possible to schedule a time slot for the operation of the sign
in order to save energy during periods where lighting of the LEDs is not
necessary.
Example: near a school, it makes it possible to schedule the lighting
according to the school entry and exit times.
Doppler radar:
This radar is capable of detecting all types of vehicles approaching or
moving away from it. It is also possible to programme a speed threshold,
ideal for limit signs.
Size detector:
Detector with an adjustable height enabling the activation of a light system
when a vehicle exceeds the size limits.
Counter direction detection:
Sensor enabling the start-up of a light system during the detection of a
vehicle moving in the opposite direction.
Twilight sensor:
Automatically adapts the light intensity according to the ambient luminosity.
Temperature sensor:
Adds a temperature threshold for the activation of the sign.
Synchronisation of the lighting of the signs by modem or radio:
Enables the simultaneous operation of signs to the side and on the centre
line on the same road, or the synchronisation of several signs on succes-
sive pedestrian crossings.
Delay system:
Keeps the sign lit up for a pre-defined time following the issue of an
activation request via a modem or radar.
Sequencer:
Sequences the flashing of the LEDs of several parts of a sign or of several
signs.
Pedestrian call button:
Activation of a sign or light system after a pedestrian presses a button
provided for this purpose.
