Fire regulations of different countries require that a monthly test is carried out on each battery back-up emergency lighting to check for functionality. Existing practice requires a team of maintenance staff to carry out the test manually at each lighting point, which is unreliable, inefficient and tedious. An innovative maintenance system is proposed to cater for this issue. It has several advantages over the existing practice – high reliability, cost effectiveness and user friendliness. With simple modification and the inclusion of LonWorks technology, an intelligent control node is proposed for carrying out the test regularly and sending the test results to a main terminal at a remote centre over a control network. Any defective lighting point can be easily spotted and repairs can be carried out promptly. Also, the system can be integrated with the existing building automation system to form an integrated system to facilitate building management.
