Cyclo Systems are pleased to announce the agreement to the upgrade of both hardware and software control systems to EDF's existing Z-LYNK powerline management system. This development project will provide enhanced remote control and access functionality together with the latest transmission hardware. This will ensure the system continues to provide reliable and efficient load management 24 hours a day, 365 days a year across the existing powerline infrastructure in one of the most demanding capital cities in the world.

Cyclo Systems are pleased to announce that they have agreed a trial with the Corporation of London 'www.cityoflondon.gov.uk' of an enhanced version of their powerline control system, currently used for all public lighting and signage control within the City of London to include a status and reporting feedback mechanism using low power radio technology.

As part of our goal to open up markets in the Asia-Pacific region Cyclo Systems International is pleased to announce its association with CPG FM Technologies of Singapore 'www.cpgfm.com.sg'.

CPG FM are a leading building and infrastructure development and management company with a prestigious client base not only in Singapore but also in China, India, the Middle East plus many other Asian countries. As part of their energy management technology solutions CPG FM will include Cyclo Systems technology for various energy management and remote public lighting control and reporting applications. Cyclo systems International are committed to working with CPG FM and building a partnership towards providing both innovative and environmentally sound energy management solutions.

Atlanta, Georgia-September 20, 2002 - Cyclo Systems International announced its plans to introduce Z-LYNK, a load switching communication solution for large industrial electric users in the North and Latin American Market. Based on its proven CycloControl Power Frequency Communication (PFC) transmission technology, the system is designed for implementing load switching in large industrial facilities and campuses where wiring or wireless connections are not reliable or cost effective.

A Z-LYNK system consists of a transmitter, control software and receivers. The transmitter embeds switching information on the power supply waveform, which delivers it to receivers located at the sites to be switched on or off or otherwise configured. This is accomplished without the requirement of an additional carrier frequency and provides instantaneous and complete coverage of the electric network to which it is connected.

Z-LYNK is used for the switching communications function in a wide range of load control applications. Some applications are load shedding for curtailment, load shifting from peak times to off-peak times to take advantage of real-time rates and load rotation to reduce maximum demand charges. Other uses include remote switching of electric devices where wiring or wirelesses are not suitable.

Cyclo System's Z-LYNK System may be interfaced with popular energy control systems through standard industry protocols. Z-LYNK system transmitters are connected at various voltage levels ranging from low voltage (408V) to as high as 33KV and propagate the CycloControl signal downstream in the electric distribution network. Since the signal operates at the power supply frequency, coverage is 100%. A powerful cyclic redundant checking (CRC) information coding scheme is used to ensure virtually error-free (1 undetected bit-in-error in 10exp11 bits transmitted). The Z-LYNK transmitter requires no tuning or other adjustments after installation.

Z-LYNK receivers also provide the load switching contacts. They are compact, easily installed and are available with ratings from 5 to 80 Amps. Each receiver is individually addressed and a basic system is capable of providing as many as 65,535 addresses. Receivers also may be activated in groups or all simultaneously to suit various load management strategies. Since Z-LYNK receivers derive their power from the circuit to which they are connected, no separate power supply is required. Contacts built into the in the Z-LYNK receivers are self latching so as to remain in the open or closed position in the event of the loss of power.

The Z-LYNK system may be remotely controlled from any convenient location. Cyclo Systems' CTCS Windows based software operates the system through any conventional communication media from RS232 to GSM and IP capable connections. The CTCS software enables users to schedule the switching of each load based upon a time-of-day, day-of-the-week schedule from external load management devices i.e. facility automation or peak demand control systems.

"We are very pleased to bring this highly cost effective and reliable communication solution to the North American market to enable large power users to more effectively control energy use," said John Queripel, Cyclo System's Managing Director. "Z-LYNK systems are in daily service around the world and have provided millions of hours of trouble-free service. We believe them to be ideally suited for the trend towards more effective energy management that is taking place in the US, Canada and the rest of the Americas," he added.

Cyclo Systems International is a privately owned developer and manufacturer of specialized communications systems using Power Frequency Communication technology. Based in Stoke-On-Trent in the United Kingdom, the company pioneered the improvements in and expanded on the core technology of CycloControl. The company now produces a unique line of products, which have found application in major metropolitan as well in remote areas. Z-LYNK systems are in use throughout the world including Europe, South Africa, China and New Zealand.

Cyclo System's North American operations will be initially based in Atlanta, Georgia.
