Reducing the labour required for emergency preparedness Computerized, centrally-managed emergency lighting systems lower maintenance costs and ease compliance with safety codes In the interest of public safety, building and life safety codes for exit signs and emergency lights require that a building owner/manager conduct a functional test every month, conduct discharge tests annually and keep a log book of maintenance information. Complying with these standards using facility management personnel to cover a large building or multiple buildings can quickly add up to many hours of costly, qualified labour in order to manually inspect and test every individual unit and record the results. Thanks to new computerized emergency light monitoring systems, however, it is no longer necessary to incur the cost of labour-intensive testing. By implementing a centrally-controlled system, these tasks can be performed remotely, greatly reducing the need for labour. EMERGENCY LIGHT MONITORING: HOW THE SYSTEM WORKS A computerized emergency lighting system is a combination of a communication network and single point emergency light units located throughout a building or buildings. Each single point unit is an emergency lighting fixture that stands alone and includes its own rechargeable battery and charger equipment. When normal AC power fails, the unit turns on its emergency lamp until the power is restored or the battery discharges. The monitoring system communicates using a centrallylocated server, which can be a computer or controller. The flexibility of the centralized system allows individual emergency light units to be assigned to groups that represent departments, floors or other logical divisions. The central controller can test and report on the status of all emergency lights in real time individually, in groups or system-wide. The network passes messages to and from the emergency

units to instruct the units to perform a task, such as turning the light on or off, and to report back to the controller to give the unit’s status, for example, whether or not the lamp is working. Computerized emergency lighting systems can use a variety of means to communicate, including a dedicated communication cable wired between every emergency light and wireless communication. WIRED AND WIRELESS VERSIONS ELIMINATE INSTALLATION CONSTRAINTS System design is entirely flexible, with both wired and wireless versions available. The wired system uses a dedicated cable network, making it ideal for areas where wireless communication is not possible. A wireless system that uses radio frequency (RF) communication and 900 MHz mesh networking technology can penetrate dense building materials, including masonry walls. With an RF system, an area controller acts as a web server, which can be set up to allow access to a remote computer. A wireless system can greatly reduce installation costs, particularly in small sites, sites with multiple buildings or complex layouts, heritage locations, and in sites with complex IT networks where firewalls may have interfered with the cabled system. With new wireless options, installing an automated emergency lighting and exit sign monitoring system is now faster and easier than before. SYSTEM AUTOMATION IS THE KEY TO INCREASED EFFICIENCY AND REDUCED LABOUR COSTS With a remotely-managed computerized system, the building manager can see the real-time status of the entire emergency lighting and exit sign system, run system diagnostics,
