Abstract
An atmospheric abnormality detection system includes a command discriminator and a display/alarm circuit in each sensor terminal. When the command discriminator receives a coincidence signal from an address comparator, the command discriminator causes an A/D converter to convert an analog sensor output to a digital signal as response data. When an abnormal state display command is transmitted from a main unit to the command discriminator, the command discriminator causes the display/alarm circuit to display information indicating the abnormal state and/or generate an audible alarm.
