The invention provides a passenger conveyer with a control device. Alarm must be given first before operation of the passenger conveyer during maintenance; only when the normal operation order is guaranteed can the passenger conveyer be operated. Only when alarm is given through the switching-on operation of an alarm switch and the switching-on operation of a rising switch or a lowering switch is performed after the switching-on operation of the alarm switch can the passenger conveyer be operated. Therefore, only when the alarm is given for warning and the rising switch or the lowering switch is free of switching-on fault can the passenger conveyer be operated and the safety of maintenance is improved.
