Centralized alarm system for vehicles

A centralized alarm system for vehicles, having sensors provided on various parts of a vehicle for detecting the conditions of said parts, a control section for controlling signals generated from said sensors, and an indicating section for indicating the conditions of said parts according to signals generated from said control section, comprising, a main alarm device, local alarm devices corresponding to said parts to be inspected, an OK-indicator, a check switch, a circuit adapted to give said control section a command for indicating abnormal parts or for indicating the parts to be inspected in response to a signal produced when the check switch is closed, said circuit having means so that when one or a plurality of said parts are detected to be functioning abnormally, the main alarm device is turned on first and then the parts found to be abnormal are indicated by manually closing said check switch, and so that, when no abnormal part is detected, the OK-indicator is turned on and the inspected parts are indicated by the manual closing of said check switch.

A centralized alarm system for vehicles, having sensors provided on various parts of the vehicle for detecting the conditions of said parts, a control section for controlling signals generated from said sensors, and an indicating section for indicating the conditions of said parts according to signals generated from said control section, said indicating section being provided in one indicated window, and comprising, a main alarm lamp device, local alarm lamp devices corresponding to the parts to be inspected, an OK-indicator, said main and local alarm lamp devices and said OK-indicator being provided collectively in one indicating window, a check switch, a circuit adapted to give said control section a command for indicating abnormal parts or for indicating the inspected parts in response to a signal produced when said check switch is closed, and means in said circuit so that when one or a plurality of said parts are detected to be abnormal, the main alarm lamp device is first turned on and the abnormal parts are indicated when said check switch is manually closed, and wherein, when no abnormal part is detected, the OK-indiator is first turned on and the inspected parts are indicated when the check switch is manually closed.

A centralized alarm system for warning of abnormalities in a plurality of components, in particular for a vehicle, comprising, a plurality of sensors, each associated with a component for producing an abnormality signal when the associated signal becomes abnormal, a control circuit connected to each of said sensors for producing a main indication signal when any one of said sensors produces an abnormality signal and for producing a local indication signal for each sensor producing an abnormality signal, a plurality of local indicators, each associated with one of said sensors and connected to said control circuit, each being capable of producing a perceptable indication and a main indicator connected to said control circuit for producing a perceptable indication when a main indication signal is produced in said control circuit, said control circuit including system checking means connected to said main indicator for turning the main indicator on when a main indication signal is produced, and manual component checking means connected between said main indicator and said local indicators for individually turning said local indicators corresponding to sensors which have produced an abnormality signal on.
