Commonly Asked Questions About GUARDIAN®

WHAT HAPPENS IF WE LOSE POWER TO THE HUB?

If there is a power cut, or loss of power, your system will switch off. We will receive a no data report and will inform the designated administrator who can check if it has been switched off by accident. If it is a real power cut, the hub will automatically switch back on when power returns. Until then the nodes will store the data in a cache and send to the cloud to report once power is reinstated.

WHAT FREQUENCY DOES THE
SYSTEM USE?

All communications via the nodes and hub are carried out via a secure LoRa private network, established by the system once installed. 868MHz, is the standard for Europe and many other regions. Other frequencies available are 915MHz and 433MHz

to enable compliance

with all current

international standards.

WHAT HAPPENS IF THE BATTERY
RUNS OUT?

Battery status is reported via the Plexus Innovation Portal, so will indicate if a replacement is

imminently required

If the battery dies, data will stop being measured until a replacement is installed. We can supply replacement batteries for user installation or we offer a return to base service for battery replacement

or node exchange.

HOW MANY NODES CAN BE SUPPORTED BY EACH HUB?

Up to 50 nodes.

150 sensors/measurement points. 

To expand beyond 50, simply add another hub.

CAN WE ADD MORE NODES LATER?

Yes, of course, up to the limits of the existing hub(s).

We are very flexible and are happy to work at your speed.

HOW LONG DO NODE BATTERIES LAST?

This depends on several factors but typically model N1 nodes, with three sensors and measuring every minute, will last 3 years before they require changing. N1/F node batteries will have a lifetime more than10 years.
