United States
Ajax Systems has reached another major milestone in the USA and Canada: Ajax hubs meet Level A4 requirements for system reliability under the ULC S304 standard and encrypted communication demands under UL 2610. For Ajax Systems, this process also became a unique opportunity to help shape compliance criteria, aligning them with the realities of modern security systems.
What are UL 2610 and ULC S304
In North America, security system benchmarks are prominently shaped by two leading safety science organizations — UL Solutions and UL Solutions in Canada. They develop standards, certify products, and audit compliance to help manufacturers build high-quality security solutions for the USA, Canada, and international markets.
UL 2610: secure system communication
The UL 2610 standard establishes requirements for commercial alarm systems, with a strong focus on secure communication. Ajax devices comply with the encrypted line security criteria, covering communication supervision, encryption, and integrity.
This compliance further confirms the reliability of Ajax systems' advanced sabotage protection, previously validated through NIST certification.
ULC S304: dependable security architecture
The Canadian ULC S304 standard defines control unit reliability, integrity, and resistance to tampering. It classifies system security into four levels, with Level A4 as the highest. Achieving this level means that a system has successfully passed rigorous testing across key criteria:
- Physical security: reinforced enclosures, tamper alarm, and anti-removal mechanisms
- Electrical protection: resilience to power surges, reliable behavior during power loss, and backup power support
- Signal integrity: secure, encrypted communication with rapid detection of faults or interference
- Operational reliability: stable performance under prolonged stress and extreme environmental conditions
- Failover and redundancy: continued operation during partial failures or targeted disruptions.
Evaluation that drives evolution
Currently, compliance with both UL 2610 and ULC S304 standards has been achieved for Ajax control panels available in the North America region — Hub 2 (4G) Jeweller and Hub 2 Plus Jeweller. Compliance details are available in the official UL Prospector.

Beyond certification, reaching Level A4 within the ULC S304 framework became a unique case of co-shaping industry standards with the certification body. The last comparable level of compliance was achieved years ago by legacy systems built on older technologies. Therefore, the Ajax team worked closely with UL to update their requirements to today's technological realities, setting a new industry precedent for how modern security systems are assessed.
The certification of Ajax systems to Level A4 was a landmark achievement, rooted in a spirit of innovation and close cooperation with UL. When it became clear that legacy test protocols were not yet adapted to the complexities of modern IP-based architectures, Ajax and UL worked side by side to bridge the gap.
By sharing deep technical expertise, Ajax helped UL pioneer an extended testing procedure that modernized industry benchmarks for digital communication security. This collaborative effort ensured that advanced technology was matched with equally advanced evaluation methods. The result is a certification that reflects both Ajax's technical excellence and a shared commitment to elevating global security standards.
Why this compliance matters
Compliance with UL 2610 Encrypted Line Security and ULC S304 demonstrates a high level of system trustworthiness, making the system suitable for Class A security installations.
This enables Ajax devices to be used for protecting critical infrastructure, high-value commercial assets, and environments requiring government-level protection. For Ajax partners, it opens opportunities to work with high-security facilities such as banking and financial institutions, military and government sites, data centers, and other high-risk commercial or industrial locations.
Technology that redefines standards
Committed to the highest levels of protection and reliability, Ajax solutions continuously push technological boundaries. The systems not only comply with global standards but, in some cases, surpass them, which becomes the driving force for the evolution of industry expectations. This new level of collaboration with laboratories and authorities helps raise the bar for modern security and, as a result, shape a safer environment.
