References low
The low reference reading is used to determine that the line on which the device is connected is
healthy and is not subject to residual or unwanted signals. For effective operation of the line this
value must be below 10. A reading of zero is quite usual.
If the low reference reading ever rises above 38 then the panel will treat the device generating
the reading as invalid.
Device status reading
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.
