Specification Suggestions
The Ubiquity Site Gateway shall be microprocess-based, suitable to perform remote monitoring and alarming
The Ubiquity Site Gateway shall be programmed using a browser per the instruction manual. It shall support
uploading of alarm and trend data to the Ubiquity Central Servers. Alarms shall be kept in non-volatile memory.
The Ubiquity Site Gateway must support non-volatile storage, so that in the event of power loss, all programmed
operating parameters shall be unaffected when running without the use of battery backup. All control functions
shall continue in the event of an Internet communications failure.
The Ubiquity Site Gateway must have energy metering and monitoring abilities. It must be able to accurately
monitor energy demand and consumption. The Ubiquity Site Gateway shall be able to communicate energy
demand and consumption to a centrally based server where it is trended.
The Ubiquity Site Gateway shall provide local communications in accordance with RS-485 standards. It shall send
and receive encrypted data over an Ethernet connection. The Ubiquity Site Gateway shall be model QD2040a as
provided by TCS Basys Controls.
