I have yet to hear any negative comments from the field on your product.  As you can imagine with the nature of your product, it is the unsung hero of the operation. It fights the battle behind the scenes and they only time people bring it up is if it had a catastrophic failure… and to the best of my knowledge we have had none of those!

We have had no recent design activities for active vehicle barriers so no real opportunities to engage your product in this application.  The one thing that did surprise me greatly during our communication with the barrier manufacturers is the lack of SPD in their standard package. For a device that lives outside in some of the worst environments on the planet, one would think that they would do everything possible to make it as robust as possible… especially since this is classified as a life safety device… it has the ability to protect life but when it fails it has the capability of killing someone.  To me that means boot straps and suspenders to make sure it does not fail.

Again, I would recommend to continue working with the barrier manufacturers, to try and get them to offer SPDs as a standard installed feature. It adds minimal cost to the system and can dramatically increase system reliability. If the barriers ever fall under a UL category that may be a good opportunity to leverage the standard to include SPDs.

If you have a new catalog, I would not mind getting a copy of that for my library.

Thank you and have a good day.
