The panel interprets the reading according to the device type. The panel uses sophisticated
algorithms based on these readings and their change over time to determine the true conditions
in the area covered by the device. Viewing a snapshot of the analogue readings cannot provide
information with the same degree of accuracy; nevertheless values can be interpreted, as in the
following tables, in order to help assess the status of a device.
Analogue status – idle limits
The resting values of the analogues when devices are in normal conditions are provided in Table
33. The resting value is referred to as the idle value and can take on any values in the ranges
given below, usually this will be near the mid-point of the range.
