Graphic Central/XBS-i System

This system was introduced in the mid 1980's. This was an upgrade for the Excel Classic system. It basically had a gateway interface that was connected to a PC running the Graphic Central/XBS-i software. The gateway supported a maximum of 14 HVAC/Fire buses. The buses supported proprietary fire and HVAC controllers. The HVAC controllers could do any control action whatsoever and were fully capable of DDC. Later the sytem was made backwared compatible with the older Honeywell systems. In its entirety the system is quite large and extensive. It can run an entire compus with ease. The system is quite efficient and very reliable. It is extensively progasmmble. It is not a system that can be installed and supported without extensive training and technical support.

CITS has all information on this system and all of its documentation and other tools used to install, service and support this system. CITS can also repair all hardweare on this system and has stock for all of its parts. CITS can provide all services for this system including training and re-programmig it from scratch. This system was later able to act as a front-end for the older Honeywell system such as the Delta 1000, Excel Classic, FS90 and many others. This sytem can be setup in multiple configurations and some of these configurations are quite complex and it can be very hard to find qualified persons to work and support those configurations. Even Honeywell may not have trained personnel to work on some of these complex application in the field. However, we want to enter it here as a matter of recod that CITS can support and service all configurations of this system and have enough parts and equipment to srvice and support all configurations of this system indefinitley. The system was later ported to a new front-end called the 'Enterprise Buildings Integrator' which is a universal interface for all of Honeywell systems and even for non-Honeywell systems. CITS can service and support all variatons of this Universal interface also.

CITS Advisory 1

All parts for this system are now obsolete and hence the current stock is not cheap. But CITS has in stock every item for this system. Parts available for this sytem are searcahable on this website. All items are available immediately. The prices are subject to change without notice for understandable reasons.

CITS Advisory 2

It may appear to that the cost of some tof these items is pretty expensive in some absolute sense but CITS advises that even at the curent prices the items are well worth it since otherwise you will be looking at repalcing the system or upgrading it or you will end up using a lot of time searching for the items. CITS recommends immediate attenstion to your system and offers repair/replacement for everry item in this system in short order. This way you can save tens of thousands of dollars. Please, remember that even migrating just one air handler can cost over 20 thousand dollars if not more. This is because all programs will have to rewritten and new hardwar/wiring installed and new front end used. Please call a CITS engineer to get more information and a recommended path for your migration. Pleae use a safe and economical approach for your site.

In the fianl analysis, use the cuurent system, reapair/service it as long as necessary and produce the money for the replacement for the long run.

Always use a safe and economical approach and not just what is technically available. Because the latter may be exciting but may not be justifiable for your business.

Thank you
