Help, please, because I can’t find where I can buy this product in new (not used) condition.

Shortly after we released the new alarming modules Sierra Wireless deprecated the Raven XE and replaced it with the LS300 (source.sierrawireless.com/device … ies/ls300/).

You should have better luck finding these.
