I need to set up a paging system that covers a 130’ by 80’ by 16’ warehouse with an open cathedral ceiling. Two other rooms 35’ by 45’ also are included. My customer wants “all-page with talkback”. Valcom has an all-page but it is only one-way. Page with talkback can only be done on a zone-by-zone basis. Do I understand this correctly? Does anyone know of an all-page with talkback for an area of this size?
Thanks.
