A wireless bell system will always be more cost-effective when compared to a hard-wired system given the costly wiring that could be a major part of the overall system installation cost. The most economical system utilizes the VNS2211 bell controller, which starts at approximately $650, which includes the controller and one speaker. A standard wireless break bell system would include a VS4820 paging base station and a single VNS2610 wireless PA speaker and start at approximately $1550. The actual cost of each wireless bell system is based mostly on the number of speakers needed to provide full area audio coverage.
