STC fields 11 AC-Powered school safety systems for Madison Borough, NJ
TEMPE, AZ - 03/04/2010 - Madison Borough, NJ recently purchased 11 AC-powered school flasher systems designed by Solar Traffic Controls with 3M
Driver Feedback Urban (DFBU) radar signs. Installation was completed by Jen
Electric.
The equipment was to replace pre-existing AC equipment which was
non-functioning due to age. For ease of retrofit, STC designed the systems
around the existing, power ready AC line already available on the poles. The
project uses AC flashers and an AC-to-DC converter unit powers the radar
signs.
During non-school hours, the system flashers and radar sign are dark and the
speed limit is regulated by a static speed limit sign. During school
hours-morning drop off, midday and afternoon release- the AC flashers and
the radar sign are activated. Driver's speeds are displayed on the radar
sign and the AC LED lamps augment the radar sign. Together, they provide a
reminder to drivers of the reduced speed limit in the school zone during the
schools designated periods.
Time-based operation of the units is accomplished using the STC-01 time clock. With 11 units to program STC provided a complementary STC-01 Desktop
Programmer (STC-01DTP). The DTP allows the school schedule to be programmed
right at the user's desk without the need of a computer, PDA or interface
cables. Once the program is entered and verified it is uploaded to a memory
chip, the memory chip is taken to the field and inserted into the field
clocks where the program copies itself into the field clocks.
The project required furnishing 11 of the new 3M Driver Feedback Urban
(DFBU) radar signs. The sign features an LED display with both yellow and
red characters, steady or flashing display and auto night dimming. The sign
also includes embedded white LED lamps used with a strobe function, data
logging, high-speed blanking and user adjustable thresholds. Signs are
configured for 12 VDC operation, are solar friendly and can be run from an
AC/DC power supply.
