A monitoring system (40) for a passenger conveyor (10) comprising: at least one acceleration sensor (42) provided on a movable component (22, 26, 30) of the passenger conveyor (10), wherein the moveable component (22, 26, 30) moves in a closed loop path (P) when the passenger conveyor (10) is in use; a fault detection sensor (44) associated with the or each acceleration sensor (42) and configured to provide data indicative of a fault in the moveable component (22, 26, 30). The monitoring system (40) includes a controller (50) configured to: receive data from the or each acceleration sensor (42); monitor a gravity vector (V) of the or each acceleration sensor (42); determine a direction of travel of the or each acceleration sensor (42); determine a current location of the or each acceleration sensor (42) 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 (44); identify a location of the detected fault based on the determined current location of the associated acceleration sensor (42).
