The device status reading is sometimes also referred to simply as the analogue
reading. It is a precise indicator of how strongly the device is sensing the
environmental factors (e.g. heat or smoke) it is designed to detect. For some
devices the analogue reading may indicate some other measure such as the
status of a switch.
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.
The resting values of the analogues when devices are in normal conditions are
provided in Table 53. The resting value is referred to as the idle value and can
take on any values in the ranges given below, usually this is near the midpoint of
the range.
