I was roaming the internet and i happened to remember a site that had a diverse mix of siren's, all of which are different. But when Josh asked me about the range on a 2t22 I went to go look it up. We stumbled across two sirens which all split off from the model 7T. Scroll down in the following map below and find Model 7TT and 7TTT. Can someone tell me and Josh what the difference between the two are. All information would be appreciated Thanks.
