Continuous Monitoring and Alarms

RF500 transmitters provide a continuous monitoring activity as opposed to a standard logger. This technique allows an RF500 system to reduce the amount of data logged but still able to detect any out-of-limit Events even if their duration is less than the log rate. This has several benefits for a wireless monitoring system.

A standard temperature logger set for a log rate of 15 minutes will only sample the temperature once every 15 minutes. This means that any out-of-limit periods with a duration of less than 15 minutes could be missed entirely.

RF500 transmitters sample the inputs at 1 minute intervals making RF500 much more responsive to out-of-limit Events. Samples taken at the log rate are logged to memory at transmitted via radio to the Gateway. If however the input goes out-of-limit then extra readings are logged and alarm Event notifications generated if necessary.

See the section on Transmitter Alarms for an explanation of how alarm Events and extra readings are generated.
