You said a lot. I have three rooms 1 is 130’ X 80’, two are aprox. 40’X 60’. All are warehouse space except one of the smaller rooms has a bagging machine in it. You can talk over the noise of the machine but it is rather loud and I think presents a problem there. My customer would like to be able to page with all-page and talkback to all rooms at once. This warehouse stores animal feed and supplies to both large farms and individuals with pets. They have a grain mill and can do custom blending in large volume. The area can get dusty. The large building is open with two rows of metal shelving. It has 16’ walls with an open ceiling to a 5 X 4 pitched roof. It is a new building. The other two rooms are like an older wooden New England barn. Post and beam with 8’ to 10’ceilings. The help is always on the move so a paging system would be ideal. It’s a one-time charge and no batteries to change or equipment to replace.
