Plural sensor monitoring and display device

DETAILED DESCRIPTION We claim: 1.
In a monitoring device for monitoring the outputs of a plurality of sensors and displaying appropriate information, said device comprising: a plurality of input gate circuits for connection to the plurality of sensors; scanning means operatively coupled to said input gate circuits and adapted to sequentially scan said input gate circuits to detect the presence of any activated sensor and to open any scanned gate which has an input signal during the period it is being scanned; a plurality of display devices for sequentially displaying information corresponding to any activated sensor, said display devices including lamps controlled by respective lamp gate circuits; a timing circuit for controlling the display time of the display devices; the improvement comprising an integrity circuit operatively coupled to said input gate circuits and to said display devices and adapted to inhibit the actuation of all of the display devices for a predetermined period following detection of an activated sensor.
