How long must an alarm business keep the training records for a system on file?

An alarm business is required to keep training records for a system on file for a minimum of three years. This duration ensures that sufficient documentation is available to demonstrate compliance with state regulations and to provide evidence of the training that personnel have received in operating alarm systems. By maintaining these records, an alarm business can also monitor the certification and skill level of its employees, which is crucial for maintaining safety and service standards in the alarm industry. The three-year requirement strikes a balance between adequate record-keeping for regulatory purposes and the practicality of managing historical data.
