摘要
The mains and back up supply for emergency lighting (35) has a monitoring unit (2') that checks the status of the supplies (2,3). The output of the main distributor (1) connects with individual lighting distributors (7,10,11,12). In the event of a main supply power failure the back up supply is switched in to maintain the lighting.
