(Specifier Note:  The purpose of this guide specification is to assist the specifier in correctly specifying a battery monitoring system and its installation.  The specifier needs to edit the guide specifications to fit the needs of specific projects.  Contact a Cellwatch Product Representative to assist in appropriate product selections.  Throughout the guide specification, there are Specifier Notes to assist in the editing of the file.

References have been made within the text of the specification to the current Master Format Section numbers and titles; specifier needs to coordinate these numbers and titles with sections included for the specific project.
