Title: Plural sensor monitoring and display device

Abstract: A monitoring device for monitoring the outputs of a plurality of sensors and displaying appropriate information. The device has a plurality of input circuits for connection to the plurality of sensors. A scanning means is arranged to sequentially scan the input circuits to detect the presence of any activated sensor or sensors. A plurality of display devices sequentially display information corresponding to any activated sensor or sensors. The device also includes an integrity circuit which inhibits the actuation of the display devices for a predetermined period following detection of an activated sensor, whereby transient or random noise signals received by the input circuits are ineffective to activate the display devices.
