Supporting safety in evolving access control environments
As physical security systems become more integrated and intelligent, evaluating the performance and safety of each component is critical. UL 294, the Standard for Access Control System Units, provides a standardized framework for testing and certifying access control devices, helping manufacturers meet applicable requirements for reliability and function.
End-to-end system integrity for modern access control
Access control systems are foundational to facility security. They help manage entry and exit points, mitigate risks such as theft and vandalism, and contribute to the overall safety of people and property. From traditional keypad entries to advanced biometric authentication, the goal remains the same: admit authorized individuals and restrict unauthorized access.
Modern systems often include:
- Control units – The decision-making hub, validating user credentials.
- Human Machine Interfaces (HMI) – Devices like smart card readers, keypads or biometric scanners.
- Indicating devices – Visual or audible signals, such as strobes, buzzers or alarms.
- Output components – Components like maglocks, Request to Exit (REX) devices and relay modules that manage physical door operations.
With the growing presence of smart Internet of Things (IoT) devices in security networks, robust testing becomes even more important to maintain system integrity and operational safety.
What is UL 294?
UL 294 defines minimum construction, performance and operational requirements for electronic and electromechanical systems that control:
- Entry or exit from secure spaces.
- Access to equipment or systems by electronic, electrical or mechanical means.
This Standard applies to systems managing one or more access points and includes optional reporting and recording functionality (though data accuracy is not assessed by the Standard). UL 294 also recognizes four levels of performance, from Level I (basic) to Level IV (high-security equipment).
- Related Standards – If an access control system includes burglar alarm functions, UL 1076, the Standard for Proprietary Burglar Alarm Units and Systems, or UL 2610, the Standard for Commercial Premises Security Alarm Units and Systems, may also apply.
