The Paxos safe lock series sets a new standard for reliability due to the consistent redundancy of the system components. It has been statistically calculated that the Paxos electronic lock system will operate for up to 15 million hours before a total failure. The locks can self-diagnose and report errors to the user via the LCD screen. With its modular design the lock system can be retrofitted with ease and updated for connection to multiple lock and input units. Paxos locks are designed in accordance with the latest technology and meet all known safety standards.
