Fire alarm system for providing protection to machine tool, has control devices staying in connection with sensors, receiving fire alarm signal using sensors and associated to objects, where sensors are respond to fire

摘要

The system has sensors (3) associated to objects (1) to be monitored, where the sensors respond to fire. Control devices (2) i.e. microprocessors, are in connection with the sensors and receive a fire alarm signal using the sensors. The control devices are associated to the objects. The control devices are connected to a common control center (4) i.e. personal computer, over a loop wiring system (5). The control devices are programmed independent of each other with respect to a setting parameter. An LED is provided to indicate status of the system.
