Emergency lighting unit and remote handset

摘要

An emergency lighting unit (10) that includes a memory (22) for storing at least one predetermined test regime and a control circuit 12 for performing mains failure tests according to the stored regime. In one embodiment a test start time offset is selected using programming switches (26). In another embodiment (see Figure 3) the emergency lighting unit (10) includes a communications unit (30) for bi-directional communication with a remote handset (40). Information concerning each test is stored in the memory (22) and may be downloaded to the handset (40). Further, information stored in the memory (22) such as a start time offset and a selected test regime may be updated by signals sent from the handset (40). <IMAGE>
