NOTICE
The table above identifies the light bar’s flash pattern
compliance. (for software revision ARJM44B or higher).
Patterns listed as “Yes” comply with the flash requirements
and light output requirements for the identified lighting
standard. Patterns listed as “No” do not comply with either the
flash requirements or the light output requirements for the
standard. A non‑compliant pattern should only be used after
those you are trying to warn have been trained to recognize
the pattern as a warning signal. The end user is responsible
for choosing the light patterns that meet their jurisdiction’s
requirements.
NOTE
Pattern 27 ‑ all lights on.
Pattern 28 ‑ each light sequentially lights for 2 seconds with
the exception of designated steady burn heads.
