A recreation of the federal signal model 5/7 siren. Model 5s use a 5hp motor and 7s use a 7hp motor I think so due to me having no other motors for right now, I am going to count this is both a 5 and 7 siren. This is 8/12 port dualtone and was created almost entirely in designspark again and has a lot of detail! This model 5 cad recreation or 3d model also includes the service pannel with realistic like clips and is the best one I've ever made.
