Emergency Vehicle Warning Systems
Improve safety by increasing driver compliance and yield rates to station-exiting emergency vehicles.
Every driver and pedestrian has experienced the momentary panic of hearing a siren from an emergency vehicle and not knowing how to react. Is the vehicle in front of or behind you? What direction is it traveling? What is your best course of action for getting out of the way and allowing them to get to their destination as quickly as possible?
Emergency vehicle warning systems like Carmanah’s, comprised of a customizable configuration of high-intensity flashing beacons and a local wireless controller, can alleviate this stress and improve safety by providing road users with a highly visible warning that emergency vehicles are entering a roadway.
Typically installed at fire halls, hospitals, and police stations—but versatile enough to be used in a variety of applications—these systems allow first responders to activate Carmanah’s compact, reliable and robust high-intensity beacons from up to 1,000 ft. away. Proven to increase awareness and yield rates, our beacons give emergency personnel the ability to exit safely and get on their way quickly.
