An emergency lighting module, comprising • a mains connection for connecting to a mains for the supply of the emergency lighting module with electrical energy, an emergency lighting module output for feeding one or more emergency lights, and a battery connection for the connection of a battery; • a charging device for charging a battery in a mains operation of the emergency lighting module, said battery being connected to the battery connection; • means for determining a mains state at the mains connection; • a DC-DC converter for converting a battery voltage which is present at the battery connection into an continuous converter output voltage for the supply of the emergency lighting module output in an emergency operation, in which the emergency lighting module is not supplied by the mains connection; • converter cutoff relays (9a, 9b) for the galvanic separation of the converter output voltage from the emergency lighting module output; • mains cutoff relays (10a, 10b) for the galvanic separation of the mains connection from the emergency lighting module output; • optionally, a static switch, in particular a unidirectional switch, for switching on and switching off a supply of the emergency lighting module output with an output current of the converter; • an electronic control which is configured to monitor the mains state, to control a switch-over from a mains operation into an emergency operation or from the emergency operation to the mains operation, and for this to control the converter, the converter cutoff relay (9a, 9b) and the mains cutoff relay (10a, 10b) as well as optionally the static switch, and to optionally display a state of the emergency lighting module; • means for detecting an external emergency state as a result of an emergency operation of another emergency lighting module or as the result of an error state of a monitored voltage at the other emergency lighting module; characterised in that the emergency lighting module is configured, on detecting the external emergency state, to generate a switch-on sequence by way of the variation of the output voltage at the emergency lighting module output and to herein generate the switch-on sequence by way of the DC-DC converter, wherein the emergency lighting module is configured, in a mains-supplied state • to feed the emergency lighting module output by way of the alternating voltage of the mains connection; • on detecting the external emergency state, to generate the switch-on sequence at the emergency lighting module output, and subsequently; • to feed the emergency lighting module output again by way of the alternating voltage of the mains connection. • a mains connection for connecting to a mains for the supply of the emergency lighting module with electrical energy, an emergency lighting module output for feeding one or more emergency lights, and a battery connection for the connection of a battery;
