Definitions of Gateway Terminology
Avg – This is the average reading recorded in the Period being
displayed. On the Home screen this is the average reading over the period of
time from midnight to the time stamp of the latest reading received. In the
summary pages the average reading could be over a much longer period of time.
Active Alarm – A transmitter can generate an alarm
event which is considered active whilst it is either unacknowledged or has a
channel still in alarm. The active state causes it to appear in the Active-Alarm
list and optionally generate reminder emails at regular intervals. It remains
active until it is both acknowledged and also the channel readings have returned
to normal.
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 –
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, a 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 log an extra
reading when there is an event to record.
Gateway Name –
A customer selectable name for each Gateway for 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 notifications. 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.
Max – This is the Maximum reading recorded in the Period
being displayed. On the Home screen this is the maximum reading over the period
of time from midnight to the time-stamp of the latest reading received. In the
summary pages the maximum reading could be over a much longer period of time.
Min – This is the minimum reading recorded in the Period
being displayed. On the Home screen this is the minimum reading in the period
of time from midnight to the time-stamp of the latest reading received. In the
summary pages the minimum reading could be over a much longer period of time.
Mesh Network – The technology used in the RF500 system
to increase wireless reception reliability. Transmitters are setup to be either
part of a Backbone or to be a regular Transmitter. Those designated as part
of the Backbone remain in RF contact with each other. By doing this the system
is able to dynamically adapt to changing conditions automatically ensuring the
integrity of the system at all times.
No Signal – The
Gateway has not received any signal from a Transmitter for a long time. Usually
1 hour or 5 times the Radio Rate whichever is longest.
Period
– A continuous session of logged records. Any break in monitoring will
result in the creation of a new logging Period.
PST –
Precision Semiconductor Technology or Thermistor, a sensor for measuring
temperature.
Radio Rate – The rate at which a Transmitter
enables its radio to contact the Gateway. The default is once every 15 minutes.
Restricted User – A user of RF500 who can only perform
a selection of functions.
Self-Healing – As part of
the Mesh technology the system is able to adapt automatically if one part of
the system is damaged, i.e. Radio Contact is lost with part of the Backbone.
Only the regular Transmitters directly reliant on the faulty part of the system
will be affected with the rest of the Transmitters simply finding alternative
routes for the data.
Snooze – The temporary disabling
of the alarm relay output due to an Active Alarm. The relay output and reminder
email notifications will be reactivated after a configurable delay if the event
is still active.
Task – The name given to the collection
of logging parameters for a specific monitoring job. Tasking is the action of
entering these parameters into RF500 and sending them to the Transmitter.
TextMagic™ – Internet Email-to-SMS provider (www.textmagic.com)
Warning emails sent from the Gateway can be converted to SMS messages using
this service. Other service providers may also work but only TextMagic has been
tested.
Transmitter – A transmitter is a device connected
wireless to the system. This device records data locally from a number of sensors
and sends the information back to the Gateway using RF. A transmitter is powered
via battery or AC adaptor.
