About Harding Technologies

Harding Technologies is a North American life safety manufacturer based in Edmonton, Alberta. Founded in 1969 as Harding Instruments by a team of University of Alberta professors, the company designs and manufactures intercom systems and Notify, its communication and emergency alert platform, and distributes the Advanced Axis AX fire alarm line across the Americas. All processes are registered to ISO 9001 international quality standards.

Harding Technologies is located at 9564 Yellowhead Trail NW, Edmonton, Alberta, T5G 0W4, Canada. All manufacturing takes place at this facility.

Harding was founded in 1969 and has been in continuous operation for over 50 years. The company opened its manufacturing division in 1974 and has been manufacturing institutional and industrial electronic products from Edmonton ever since.

Yes. All Harding Technologies processes are registered to ISO 9001 international quality management standards. This covers design, manufacturing, testing, and shipping for all products that leave our facility.
Harding manufactures intercom systems for correctional, behavioural health, educational, and institutional applications, along with Notify, a communication and emergency alert platform for schools and commercial buildings. Harding also distributes the Advanced Axis AX fire alarm line across the Americas. Additionally, Harding manufactures electronic products for other manufacturers in oil and gas, oil sands, heavy equipment, and telecommunications industries.

Harding sells directly to customers and through verified distributors across the Americas. Regional representatives support business development in their territories, but orders are placed with Harding directly or through a verified distributor. For intercom and Notify products, contact sales@harding.ca. For fire alarm products, contact SalesFireUS@harding-tech.com. Representative maps for both product lines are available on the Contact page.

Intercom Systems

Harding's intercom systems are digital systems specifically designed for high-security and institutional environments. They feature a distributed IP architecture, zero call blocking design, digital signal processing for superior audio clarity, and a fault-tolerant platform with comprehensive diagnostics. The current generation has replaced the legacy MicroComm DXI in new installations.
Zero call blocking means that no station in the system is ever blocked from making or receiving a call, no matter how many simultaneous calls are active across the facility. In a correctional facility during a critical incident, or in any high-security environment where communication cannot fail, this design is not a feature but a fundamental requirement.
Harding's intercom systems are specifically designed for correctional and high-security facilities, behavioural health institutions, K-12 schools and educational facilities, government and municipal buildings, military installations, and commercial and residential environments. They are installed in maximum-security prisons, US Army garrisons, behavioral health hospitals, schools, and commercial landmarks across the Americas and internationally.
Harding's intercom systems are designed for a service life of 20+ years. We maintain technical documentation for the full lifespan of the system and continue to support legacy MicroComm DXI systems installed decades ago through our Tech Support Hub with full documentation. When you specify a Harding intercom system, you are specifying a system with a manufacturer committed to supporting it for the life of the facility.
A Harding intercom system supports up to 6,400 stations, which covers everything from a small detention centre to a major correctional campus. Contact our technical team for guidance on system sizing for your specific facility.
Yes. Harding intercom systems are designed for integration with programmable logic controllers, door control systems, and the broader security management infrastructure of a facility. Harding works with the project integrator during the specification phase to confirm interface points and compatibility requirements before equipment is ordered.
Multiple station types are available to suit different facility environments, including standard wall-mount stations, flush-mount correctional-grade stations, tamper-resistant stations for high-security areas, and privacy stations (ICE 421/431 series) for interview rooms and legal consultation areas where audio confidentiality is required. Stations can be VoIP or analog, and analog stations are available in both 2-wire and 4-wire configurations, so the system can match a new build or the wiring already in place. Station types and faceplates are selected during the specification phase.
Yes. Harding intercom systems are fully software configurable. Changes, additions, and modifications to the system are implemented in software, which means facility renovations, expansions, and operational changes do not require expensive replacements. The modular construction also supports phased construction projects.
The DXI is our legacy intercom system. It is no longer available for new installations and is supported through our Tech Support Hub with full documentation. Our current-generation system features a distributed IP architecture for greater flexibility in large or complex facilities. If you are specifying a new build or planning a full retrofit, the current-generation system is the right choice. If you are supporting or extending an existing DXI installation, our team has the expertise to help keep it running and to plan a transition when the time is right.
Yes. Harding intercom systems include discrete audio monitoring capability, allowing authorised operators to monitor specific stations without activating a visible call indication at the monitored location. This is a standard operational requirement in many high-security environments.
Yes. The system includes audio level alarm detection, which can alert operators to abnormal audio conditions at any station. In correctional and high-security settings, this provides an additional layer of situational awareness beyond traditional call-and-respond communication.

Notify

Notify is Harding's communication and emergency alert platform. It brings paging, emergency alerts, and facility response controls together in one IP-based system, so the right message reaches the right people the moment it matters. It draws on Harding's proven intercom technology and is configured to match the way each facility responds to an emergency.
With the press of a button, or through secure access from a mobile device, authorized users can send live or pre-recorded messages, trigger lockdown procedures, and activate connected devices such as cameras, alarms, horns, and strobes. Notifications are encrypted, and the system can tell responders where an alert came from, down to the specific building or area.
Notify is designed for K-12 schools and other educational campuses, and for commercial and multi-residential buildings. In a school, a single command can announce over the paging system, lock down doors, activate cameras, and tell staff and responders exactly where the emergency is. In a commercial or residential building, property managers and security teams can reach occupants quickly and coordinate a response across one building or a whole portfolio of properties. Notify can also be set up so that any building you designate can trigger an alert across an entire district or network.
Notify is built to work with the procedures and equipment a facility already relies on, including door lockdown, cameras, and paging. Because every school and building responds to emergencies a little differently, Harding works with your integrator and project team early to confirm what connects, how it should behave, and who can trigger what. Contact our team at sales@harding.ca to talk through your requirements.

Advanced Axis AX

Harding is the exclusive distributor of the Advanced Axis AX across the Americas. Advanced Electronics is the manufacturer. The Axis AX line includes addressable fire alarm panels, detectors, modules, and bases in both UL (US) and ULC (Canadian) listed versions. Advanced Electronics is part of Halma PLC, a FTSE 100 global group of life-saving technology companies.

The Advanced Axis AX is both UL and ULC listed, a complete addressable fire alarm product line for UL and ULC projects, designed for commercial and high-rise applications. It supports up to 200 panels in a single network, includes integrated voice evacuation with PerfectSync audio synchronisation, features AlarmCalm false alarm management technology, and integrates with building management systems via the Commander field controller. It is certified to UL 864 10th Edition (US) and ULC standards (Canada).

UL (Underwriters Laboratories) is the US listing standard for fire alarm equipment. ULC (Underwriters Laboratories of Canada) is the equivalent Canadian certification. They are not interchangeable. Projects in the United States require UL-listed equipment. Projects in Canada require ULC-certified equipment. The Axis AX is both UL and ULC listed, so a complete addressable fire alarm system is available for either market. Because each country has its own requirements for how a panel operates, panels are supplied in a UL version for the US and a ULC version for Canada, while many detectors and devices carry both marks. If you are unsure which applies to your project, contact our fire team.

The Advanced Axis AX is designed for hotels and high-rise buildings, residential towers, battery energy storage facilities requiring early thermal runaway detection, hospitals and healthcare, schools and education, and commercial and retail properties. The system scales from single-panel commercial sites to complex 200-panel institutional networks.

PerfectSync is Advanced's audio synchronisation technology that ensures voice evacuation announcements are perfectly synchronised across all floors and zones of a building simultaneously. Without synchronisation, audio from different floors can overlap and create confusion during an emergency. PerfectSync eliminates this problem and is a standard feature of the Advanced Axis AX system.

Yes. The Advanced Axis AX integrates with building management systems (BMS) via the Commander field controller, allowing fire alarm events to be communicated to and coordinated with the broader building management infrastructure.

Yes. The Advanced Axis AX addresses battery energy storage system applications, providing early warning detection for lithium-ion battery thermal runaway. Early detection at the off-gas stage, before heat or smoke sensors would trigger, gives facility operators the maximum possible time to initiate a response. Contact our fire team to discuss BESS-specific requirements for your project.

The FxIP was an earlier fire alarm product line designed and manufactured by Harding. It is no longer available for new installations but is fully supported by Harding with technical documentation, legacy product resources, and phone support. All FxIP documentation is available on the Tech Support Hub.
