摘要： PROBLEM TO BE SOLVED: To provide a data transmission system and a monitoring system, capable of adding a terminal corresponding to a new data transmission system to be connected to the existing transmission line as leaving a terminal existing before corresponding to the conventional data transmission system, and collecting data.
SOLUTION: A data string is made into a structure where a mode region in which information indicating whether the data string is the one for data collection or the one for terminal control is contained, an address storage region which specifies the terminal, a command region in which information indicating the content of a command to the terminal is contained, and a return data region in which return data are contained are included between a start bit and a stop bit, the stop bit is made replaceable with an extension bit associated with waveform different from waveform showing the bit, and when the stop bit is replaced with the extension bit, the data string is transmitted as a data string obtained by adding an extra data return region in which the return data follow the extension bit.

摘要： PROBLEM TO BE SOLVED: To provide a fire receiver for carrying out various functional test and reducing the number of operation parts and display parts to have excellent operability.
SOLUTION: A plurality of fire sensors 20 sensing a fire are connected to a dwelling house receiver 30 through a designated signal line. The dwelling house receiver includes: a first test carry-out means (a control part 31) for carrying out a sensor operation test, which detects the abnormality of the sensors 20 and displays the fire sensor 20 whose abnormality is detected; a second test carry-out means (a control part 31) for carrying out a fire display test, which displays the operating condition of the fire sensor 20 in pseudo; a fire test switch 53 operated in a designated mode to transmit a signal for carrying out a sensor operation test and a fire display test to the first test carry-out means and the second test carry-out means; and a test switching means (a control part 31) for determining which of the first test carry-out means and the second test carry-out means is started depending on the operation mode of te fire test switch 53.

摘要： PROBLEM TO BE SOLVED: To provide a disaster prevention system, which can individually set an interlocked state to a non-interlocked and is convenienct at the time of system adjustment or the like, concerning the disaster prevention system for controlling plural smoke prevention equipments while being interlocked with sensing of a fire. SOLUTION: A disaster prevention system 1 is provided with plural fire sensors S1, S2... for sensing the fire and plural smoke prevention equipment ER1, ER2... for preventing the fire or smoke from being spread and controls the predetermined smoke prevention equipment ER1, ER2... based on a fire signal while interlocking them. Then, this system is provided with a batch non-interlock setting means for simultaneously setting all the smoke prevention equipment ER1, ER2... to the non-interlocked state concerning the interlock control of smoke prevention equipment ER1, ER2... based on this fire signal through an operation input and an individual non-interlock setting means for setting the prescribed smoke prevention equipment ER1 and ER2 in the non- interlocked state individually.

摘要： PROBLEM TO BE SOLVED: To exclude the influence of noises in discriminating the stain of a smoke sensor outputting a value corresponding to a smoke density from its output value. SOLUTION: A fire alarm system is provided with a high stain discriminating part 6 discriminating the stain which ascends the output value of the smoke sensor 1 and a low stain discriminating part 7 discriminating the stain which descends the value. The high stain discriminating part 6 repeats the comparison of the whole output values of the smoke sensor 1 within a prescribed time with a least upper bound value at every prescribed time. When the whole output values continuously exceeds the least upper bound value for the portion of a prescrived number, it is judged that the smoke sensor 1 is stained. The low stain discriminating part 7 repeats the comparison of the lowest output value within the output values of the smoke sensor 1 within the prescribed time with a low limit value at every prescribed time. Then, it is judged that the smoke sensor 1 is stained when the lowest output value continuously exceeds the lower limit value for the portion of the prescribed number. When the stain for descending the output value is discriminated, alarm which is different from that at the time of discriminating the stain for ascending the output value is issued.

摘要： PROBLEM TO BE SOLVED: To rapidly confirm the final page or the leading page, to eliminate overlook of events on the next page or the previous page and to confirm numbers of fire and gas leakage in real time. SOLUTION: Functions of the next page changeover switch 3 and the previous page changeover switch 4 are changed to the functions of the final page changeover switch and the leading page changeover switch respectively by pressing a function changeover switch 5. After the function change, the final page or the leading page is displayed on the screen 2 by pressing the switches. Also, the next page changeover switch 3 or the previous page changeover switch 4 becomes different from ordinary mode and events in the next page or the previous page are informed. Furthermore, the total number of fire and gas leakage is always displayed 7, 8 on the screen 2 apart from message 6 of the events.
