MULTIDIGIT monitoring system. The system makes it possible to permanently monitor single-battery safety lights from a central location. The safety lights report their current status via a LAN network to a PC with a web browser, which takes over the evaluation and control of the entire system. This means that the system status can be viewed immediately and clearly and a statement can be made at any time about the operational readiness of the safety lighting system. 125 single-battery safety lights can be installed. Alternatively, up to 125 signal amplifiers, each for 125 lights, can be connected to the bus output of the module, thus increasing the number of monitored devices to up to 15,625 lights. There are no special requirements for the bus line; the structure can be T-shaped, star-shaped, linear or mixed. The polarity of the bus line does not have to be observed. Maximum length of the communication line 1,000 meters, 2 x 1,000 meters when using signal amplifiers. Functions: Automatic configuration of the system. Reporting of all faults in plain text with location details. Coordination of test times for all self-contained emergency lights. Logging of error messages. Detailed information and control options for each individual safety light. Continuous logging of all system faults. Automatic maintenance of a detailed test log for the system. Minimal costs for the prescribed checks of the emergency lighting system. Password protection for changes to system data. The module can be queried from any intranet/internet-capable PC connected to the network using a web navigator without special software. The data stored in the module is sent to the navigator via the network using the TCP-IP protocol. If a fault occurs in the system, this is immediately displayed in the navigator window. Using the built-in email function, detailed information about the fault can be sent to the system manager. With the appropriate network configuration, the system can also be accessed via the Internet.
