Howler Siren Use

After trying out the system, MEMS is now in the process of adding the "Howler" siren to our emergency warning system. Each remount will have the addition of the Howler as a standard feature. We are currently retrofitting the supervisor's vehicles. Here is a brief description of how to operate the system.


The Howler siren is to be used just as you would use your air horn. It is set up on an 8 second timer so once activated it will run and then time out and shut off. The switch is located next to the air horn switch. While the siren is activated just push the Howler button when needed. It will change tones automatically as you change them with your siren. If you want to deactivate it before it times out simply push the switch again. Howler provides deep, low frequency tones, which are able to penetrate other vehicles, alerting drivers and pedestrians of your approach. Howler is not a replacement to the vehicle's primary siren; Howler adds a minimum eight second penetrating burst of low frequency siren sound for use in heavy traffic, intersections or other high ambient noise conditions.


Any questions please feel free to come by the Shop and we will demo it for you.
