Fire Alarm Battery Tests
In March of 2025, the California Office of the State Fire Marshal (OSFM) issued a code interpretation clarifying that NFPA 72 does not require power to be disconnected for a 24-hour period as part of a battery test (see OSFM CI 25-03).
On July 2, DSA announced modifications to DSA requirements pursuant to OSFM CI 25-03. Based on early feedback from stakeholders, DSA provides the following clarification: DSA will not require disconnecting power for 24 hours prior to commencing battery tests. Two related slides have been updated to reflect the revised DSA requirements for battery testing based on the OSFM interpretation.
