G SERIES USER MANUAL
2.0 INTRODUCTION
2.9 RRFB Light Bars: Overview
Standard G Series products support up to four RRFB light bar fixtures, or up to eight for dual EMS systems. The
FHWA Interim Approval 21 March 20
th
, 2018, defines the flash pattern of the RRFB and specifies the J595
standard for photometrics. Each light bar consists of a left and right module, with each module having eight LEDs
connected in series. In addition, each end of a light bar has a single “confirmation” LED that pedestrians can see
from across the street and know with confidence that the light bars are flashing in response to their pressing of
the pedestrian pushbutton. Opaque adhesive covers are included to optionally cover the confirmation LED if
desired.
See
for information on installing and aiming light bars.
When programming intensity for
RRFBs
, minimum current settings must be applied to maintain
SAE J595 compliance, (see
Intensity
). Contact Carmanah for
guidance.
