Definitions of Gateway Terminology
Avg – This is the average reading recorded in the Period being displayed. On the Home Page this is the average
reading over the period of time from midnight to the timestamp of the latest reading received. In the summary pages
the average reading could be over a much longer period of time.
Backbone – A transmitter during setup can be designated to be part of the Wireless Network Backbone. This
requirement is identified during site surveys. A Backbone transmitter will be mains powered and constantly active. It
will therefore (almost) always be available to re-transmit messages received from nearby transmitters.
Event Logging – All transmitters have the capacity to measure from one or more sensor inputs at a number of pre-
defined logging intervals. However should an alarm event occur between log intervals then the transmitters will wake
up to record this event. As soon as the alarm is triggered, the transmitter will wake up and transmit the alarm back to
the Gateway via the mesh network. This technique allows for long intervals between logging static readings knowing
that if an alarm does occur it will be captured. This results in a robust system that will log an extra reading when there
is an event to record.
Gateway Name – A customer selectable name for each Gateway enables easy identification.
Last – This is the last known good reading from the transmitter. It does not imply that the transmitter is functional or
currently within range.
Location – A logical grouping of transmitters for the purpose of filtering and directing alerts. These Locations
may correspond to the physical siting of transmitters but more usually group transmitters monitoring equipment or
environments “owned” by an individual person or department.
Login Page – A user name and password are required in separate pages to log in to the Gateway to perform any
setup changes or maintenance.
