DoorKing’s new 900MHz Wireless Expansion Kits let you add access ponts in those hard-to-wire places, eliminating costly labor, trenching and conduit runs. Simply add a base station to a DKS telephone entry system, and a remote station (up to 48 of them) to a DKS access device and the wireless connection is made seamlessly, up to a 1000′ range. DoorKing even has a repeater for those hard to reach remote sites, doubling the wireless range.
