How to use this page
Fire alarm tools support battery backup, loop load, address capacity, and DIP switch checks. They are intended for quick verification during design coordination, shop drawing review, and site troubleshooting. Final fire alarm design must follow the approved system manufacturer guidance, local civil defense requirements, and project cause-and-effect matrix.
Use the tools to catch capacity issues early, document assumptions, and support review conversations before final approval.
