摘要： A thermal analog fire detector which is excellent in measurement precision and resolution in both the high and low temperature ranges and which has a wide range of measuring temperatures. A constant voltage E from a constant voltage circuit is supplied to a CPU, an A/D converter and a constant current circuit. The constant current circuit is connected in series to a thermistor. The constant current circuit is constructed to supply a constant current, the value of which being variable in a plurality of stages, to the thermistor controlled by the CPU. The CPU switches the constant current of the constant current circuit according to the measured temperature data. A voltage V across the thermistor is converted into digital data by the A/D converter, and then the converted data is supplied to the CPU.

摘要： An ionization-type smoke sensor having a 2-chamber 1-radiation source structure including an inner electrode having a radiation source, an intermediate electrode having an opening through which radiation from the radiation source passes, an outer electrode through which smoke may flow inside from outside, and an insulator supporting and insulating the inner electrode, the intermediate electrode and the outer electrode. In the sensor, a fence portion made of an insulating material is formed on and projecting from a surface of the insulator which faces the outer electrode, the fence portion surrounding the periphery of the opening of the intermediate electrode. By virtue of this arrangement, even when the sensor is subjected to flow of air heading from outside toward the opening of the intermediate electrode, the fence serves to reduce the flow of air heading toward the opening, thereby enabling the characteristics of the sensor chambers to remain stable against flow of air. Since the fence portion made of an insulating material is formed to project from the surface of the insulator, the creepage distance between the intermediate electrode and the outer electrode is long, thereby enabling an improved level of insulation for the electrodes.

摘要： An automatic fire extinguishing system wherein at least two fire detecting sensors are provided. The sensors are disposed at a distance from each other and movable in the horizontal and vertical directions to scan the region to be protected for detecting the angles of a fire source in the horizontal and vertical directions. A distance to the fire source is obtained from the angles of the fire source detected by the respective sensors. A discharge nozzle is set based on the fire source position determined by the angles and the distance of the fire source.

摘要： A fire alarm system having a plurality of fire detectors connected in parallel with each other to a pair of power/signal lines leading to a central signal station and adapted to respond to the signal station with a detection signal in the mode of current and controlling the signalling between the fire detectors and the signal station. The detection of a fire is accomplished by computing a difference between a steady-state current flowing through the signal lines and a detection current which are detected in an analog amounts. Each of the fire detectors is called by a simple calling clock pulse whose transmitting timing is controlled by a microcomputer of the central signal station to transmit a detection data. The generation timing of the calling clock pulses is freely selectable to effect a desired control of the fire detectors.

摘要： A plurality of fire detectors for detecting a physical change caused by fire and a central signal station for receiving a fire signal from the fire detectors to raise an alarm are connected to each other through optical fiber cables. The central signal station transmits power light for supplying power and timing signals which are superposed on the power light for controlling operation timing to the respective detectors through the optical fiber cables, while each of the fire detectors converts the power light into electric power, carries out a fire detecting operation in response to the timing signals and transmits, upon detection of a fire, a fire signal in the form of light to the central signal station through the optical fiber cable.
