I know the ZF 7982 is at end of life. We have a lot of them and are considering reusing in remodeled buildings. Looking for a way out in the ball park idea of general principles of spacing them in open area with columns, behind sheet rock wall, concrete / plaster walls. I just have no idea about places to put them that would give me X percent coverage at X strength. I don't even know what percent or strength is basic. I've just always been told to put them here and there.
Thanks for any help or information you can pass along or direct me to.
One ignorant guy.
