The cost of a basic wireless panic button system will be the sum of the chosen panic buttons and remotely activated devices. A standard paging system could include a VS4820 base station, a single VNS2610 wireless PA speaker, and one panic button, and would start at approximately $1,600. The total cost will mostly be based on the number of wireless panic buttons, PA speakers, LED message boards, and other visual alert devices that are needed to provide full notification coverage.
