North Building Technologies

The extensible object model, XOM, is at the core of every North product and is the base-concept that allows systems from different manufacturers, in different control fields, to be linked together to form a truly integrated building control system.

The object model has evolved over many years, and is the most powerful model in the integrated building control field, incorporating fire, security, hvac, lighting, power, air-conditioning, etc.

XOM caters for simple values, such as numbers, flags, integers and times; medium-component objects, such as time-profiles, historic trends and remote procedure calling; and complex objects like file-systems, devices, controllers, processors, buildings, sites, etc. - a truly powerful model

The beautiful thing is - as new technologies evolve, XOM extends to include them. XOM already encompases standards such as BACnet, Lon, EIB, etc. allowing engineers to use these systems in a more powerful integrated building control system.

At an engineering level, North products use XOM to automatically scan and recognise attached devices and networks. So design, commissioning and maintenance are simplified.

XOM Architecture

The extensible object model communications protocol is able to operate across many different physical connections, adopting the most suitable network topology.

XOM networks are able to inter-connect across Ethernet, RS-232, RS-485 and dial-up networks.

Although engineers use XOM without realising it, organisations that wish to extend our product range need an understanding of these core mechanisms. For more details contact us.
