How long must records of all signals, tests, and operations be maintained at the supervising station for off-premises monitoring?

The correct duration for maintaining records of all signals, tests, and operations at the supervising station for off-premises monitoring is 1 year. This requirement is established to ensure that monitoring companies can effectively manage and evaluate their performance, as well as provide necessary information for audits or regulatory reviews. Keeping these records for a year strikes a balance between having sufficient historical data for operational oversight while not placing excessive burdens on the company regarding data retention and storage costs.

It is critical for alarm monitoring businesses to maintain these records to demonstrate compliance with industry standards and regulations, as they offer a record of activity that can be reviewed should there be any discrepancies or issues that arise with monitored alarms.
