The following will provide a quick overview of what you need to ensure your small emergency vehicle’s warning light system complies with NFPA 1901. A small apparatus is defined in NFPA 1901 as a vehicle with a bumperto-bumper length of less than 25 feet, and has the optical center of all optical warning devices at less than 8 feet
Each apparatus, less than 25 feet long, is divided into eight (8) warning zones – four upper and four lower.
Calling for Right of Way: Apparatus responding to an emergency. Blocking Right of Way: Apparatus at emergency scene. White light not permitted.
The minimum flash rate allowed is 75 flashes per minute for any single optical source and 150 flashes per minute from all of the light sources visible at any data point (i.e., at least two warning lights are required in each zone). Failure of a lighting device should not leave a data point without a signal.
Zone B & D Upper Level and Zone C Upper and Lower Levels are covered by the fully populated lightbar chosen in Zone A…
