Safety Features This system has several important safety features to ensure proper operation of the motor and prevent accidental damage to the engine or its components. Over and Under Rev Protection The system monitors the engine speed and will automatically shut the engine off if the RPMs rise above or fall below the programmed levels. This feature prevents damage to the motor due to fuel delivery system failures or other problems which may cause the engine to race. NOTE: The system uses a wire connected to the vehicle to sense engine speed. This wire must be connected in order for over and under rev protection to work. Shut Down Inputs This system uses several inputs to shut down the remote start operation of the motor or prevent remote start if certain inputs are active. The two most important are hood and brake inputs. The hood input will prevent the motor from starting, as well as shut it down, any time the hood is opened. The brake pedal will shut down the motor at any time during remote start operation, as well as preventing the remote start from activating while it is being pressed. 20 © 1999 Directed Electronics, Inc.
