Specialized Embedded Software Enables Machine to Machine Communication

Reliably Communicates Useful Monitoring Information

Milpitas, California – April 23, 2008 –Sierra Monitor Corporation (OTC: SRMC.OB), a Cleantech focused company that delivers information technology for environment measurement and control by developing specialized embedded software deployed on proprietary hardware platforms, announced that it has been awarded Patent Number 7,332,996 by the US Patent and Trade Office for a unique environment control system which is used by telecommunication companies' cell phone sites to monitor specific devices whose status may have an impact on the environmental condition at each cell site.

The patent covers a telephone cell site environmental control system which includes a microprocessor-based central control module that analyses various environmental conditions and issues environment management instructions for heating, ventilation and air conditioning. A key claim of the patent is the ability to monitor voltage based alarms already connected to the telephone company monitoring system. The method reduces installation costs and provides consistence of information between systems. The environment control system is designed to reduce energy consumption during normal operation and to provide extended service during power disruptions..

"We are very pleased to have been awarded this patent," said Gordon Arnold, Chairman and Chief Executive Officer. "Sierra Monitor has been an early leader in developing specialized embedded application specific software which enables intelligent environment control for remote telephone buildings. Our Intelesite product, covered by this patent, also provides a platform for further deployment of our machine to machine (M2M) protocol translation products."
