Very necessary component to making signal function
Your review: Good product, although it would have been nice if it was made MORE CLEAR on your site that this is an absolutely vital part of making the federal signaling device make noise. I read the description of the signaling device, but did not realize that also purchasing this UTM was the ONLY way of getting noise to come through the signal. Had to order the UTM last minute and rush delivery. Lead time is crazy long on this product even when you select overnight shipping as it comes from manufacturer. However, thanks to helpful staff at both Global Industrial and the Federal Signal company, product was received quicker than the usual lead time and it worked out OK.
