Terminals (12, 60) are arranged to accommodate the AEDs, the terminals comprising a communication interface and adapted to use the communication interface (49) to transmit an alert indicative of access to the terminals. A monitoring unit (14) in communication with the terminals is operable to receive the 10 alerts. Data storage (80) stores contact information for rescuers trained in AED usage, the rescuers being associated with one or more of the terminals. A controller of a transmitter initiates transmission of a message to at least one of the rescuers (70) associated with a terminal that has issued an alert.
