The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform.

BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control (HVAC), lighting control, access control, and fire detection systems and their associated equipment.

There was a time when buildings were tied to the proprietary protocols of manufacturers, so if customers wanted to upgrade or expand, they had only one supplier choice. Delta Controls felt this was wrong. They wanted people to choose their systems, and stay with them, not because we were the only option, but because their systems perform consistently, and exceed expectations.

Delta Controls has been instrumental in the development of the BACnet protocol, having played a leading role in the organization since the early nineties. Delta Controls was one of the first manufacturers to have fully BTL listed operator workstations, and has the most robust BACnet product architecture available.

BEC are members of the BIG-EU, an organisation which Promotes the development of the BACnet standard, enabling open data exchange and ensuring interoperability of different building automation components.


BACnet is designed to allow HVAC/R, lighting, life safety, access, security, power, vertical transportation and other building system control devices to work together on the same network.


BACnet affords facility owners and manager’s maximum flexibility and cost-effectiveness, by allowing control products made by different manufacturers to be integrated into a single, uniform system.


The BACnet protocol was initiated by Mike Newman of Cornell, and developed to be a consensus standard, under full public scrutiny. Today, as an international standard, it cannot be changed without public review and comment – ensuring it remains robust and practical.


BACnet is now considered the leading international protocol, gaining worldwide certification including a European standard (CEN) and ISO standard (ISO 16484-5).

The World’s first fully integrated BACnet system featuring full interoperability and internet accessibility

Delta’s building automation system includes HVAC/R, Card Access and Lighting control. It has the industry’s most extensive implementation of BACnet, native to all products through all levels of the system. We are proud of our relationship and commitment to BACnet.

Card Access System

The access control system extends Delta’s building automation system by integrating seamlessly with Delta Controls HVAC and Lighting applications. This gives you total control over your room, from the doors to the blinds and lights, there’s nothing you can’t control.

Synchronize access users across your building with enteliSYNC.
Multi-factor authentication, local authorization, and optional anonymized users ensure the protection of your personal data.
Add Power Injector Modules to control up to 24 doors on a single CPU, or save on installation by adding available PoE.
UL 294 / UL 916 certified.
OSDP protocol and Weigand input ready.

Delta Lighting System

The DLS incorporates our Delta Lighting Controller with a selection of relays factory installed into a protective cabinet. The DLS can contain modules that add functionality such as a keypad lighting interface or light dimming.

You can purchase a Delta Lighting Controller alone, or as part of a Delta Lighting System.
The DLS cabinet is assembled in our factory by trained professionals. It reduces setup issues and greatly speeds up installations. Relays are wired directly into the cabinet, making maintenance and troubleshooting a snap.
