A monitoring system for a passenger conveyor including: at least one acceleration sensor provided on a movable component of the passenger conveyor, wherein the moveable component moves in a closed loop path (P) when the passenger conveyor is in use; a fault detection sensor associated with the or each acceleration sensor and configured to provide data indicative of a fault in the moveable component. The monitoring system includes a controller configured to: receive data from the or each acceleration sensor; monitor a gravity vector (V) of the or each acceleration sensor; determine a direction of travel of the or each acceleration sensor; determine a current location of the or each acceleration sensor based on the monitored gravity vector (V) and the determined direction of travel; detect a fault from the data received from the or each fault detection sensor; identify a location of the detected fault.
