There is described an auditor system and method for a building management system environment comprising a blockchain component and an alarm remediation and auditing device. The blockchain component provides communication between the auditor system and a network of peer-to-peer nodes. The alarm remediation and auditing device provides interaction between the auditor system and one or more user, wherein the alarm remediation and auditing device is further configured to process building information associated with a selected remediation type received from the blockchain component as well as requirement for regulatory compliance. The auditor system performs an audit of transaction records of the decentralized ledger relating to the remediation type without providing any new transaction records to the decentralized ledger that relate to the remediation types of the building automation system and do not relate to the audit.

Auditor system and method for a building management system environment

Alarm issue management for a building automation system comprising a decentralized ledger as well as first, second, and third systems. The decentralized ledger has immutable transaction records validated and secured by a network of peer-to-peer nodes, and the ledger utilizes proof of work to synchronize the nodes. The first, second, and third systems access the transaction records of the ledger relating to a remediation type of a building automation system. The first system provides a first transaction record to the ledger relating to the remediation type. The second system reads the first transaction record of the ledger and provides a second transaction record to the ledger relating to the remediation type based on the first transaction record. The third system reads the first and second transaction records of the ledger and performs an audit of the first and second transaction records of the ledger relating to the remediation type.
