Secure solutions for maintenance areas and server rooms Expensive computer equipment and vital information are stored in a company’s maintenance areas, computer rooms or server rooms. Aptus access control systems and alarms protect these rooms from unauthorized access. An access control system with smart alarm control keeps your technical equipment safe at all times and only allows authorized users to access the room. Aptus multi control units notify you of events in the maintenance area such as fire or forced entry. To facilitate key management, all Aptus readers are proximity readers and our systems can be expanded with alarms.
