For how long must a fire alarm log book be maintained?

A fire alarm log book must be maintained for a period of three years. This duration is established to ensure that there is a sufficient record of the fire alarm system's performance and any incidents related to its operation. Keeping the log for this length of time allows for a thorough review of past events, which can be crucial during inspections or audits by fire safety authorities. It also ensures that any patterns or recurring issues can be identified and addressed effectively. Maintaining the log book for three years provides a balance between record-keeping for safety and practicality for facility management.
