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.
