A status monitoring unit for monitoring the status output by an emergency power unit 32, e.g. for an emergency light, taps into signals intercepted between the emergency power supply unit 32 and a status light 36 of the emergency power unit 32. A processor 120 is able to interpret the signals to detect a status being indicated by the emergency power unit 32 at the status light 36. The interpreted status is communicated wirelessly to a remote receiver. Another invention relates to requesting a status request from a remote monitoring unit together with a unique ID. |
