摘要： A light scattering type smoke detector arranged such that even if the range in which light from an LED is emitted has a dispersion, a labyrinth member 90 in the light emitting range has no edge or only a predetermined labyrinth member exist therein. The labyrinth member 90 is preferably formed by a single plate larger than the other labyrinth members 9. The edges of the labyrinth members 9 are preferably formed to a curved surface or chamfered, and the dispersion of the 0 point of a detection output is reduced and the level of the 0 point of the detection signal is lowered to thereby accurately detect light scattered by smoke.

摘要： A fire alarm system comprises a first light emitting device (11), a first polarizing filter (31), a first light receiving device (21), a second light emitting device (12), a second polarizing filter (32), and a second light receiving device (22). With the above arrangement, the amount of the parallel polarized component to the scattering plane as well as the amount of the perpendicular polarized component to the scattering plane is detected. The ratio between these amounts of light has a correlation with the type of smoke. A calculation section (4) calculates this ratio from the outputs of the light receiving devices (21, 22). A decision section (6) compares the above-described ratio with a reference value which has been preset according to the type of smoke to be detected, whereby the judgement of whether there is a fire or not is performed depending on the type of smoke. Thus, the detection of a fire can be performed from the light scattered by smoke taking into account the type of smoke.

摘要： A radio analog sensor for transmitting analog signals of a temperature or smoke density to a remote place by radio is used as each of sub devices 12-1 to 12-n. When a change of the analog detection signals of a temperature, a smoke density or the like, which is detected by the analog sensor 10 connected to each of the sub devices, is greater than a predetermined value, the analog signals which have been so far stored in a memory are collectively transmitted to the receiver side by radio. Periodic information is also sent from each of the sub devices 12-1 to 12-n once every two hours so as to supervise the state of the sensors. This permits reliable transmission of necessary data to a remote place without decreasing the life of the battery.

摘要： A double-nozzle deluge gun has a pair of nozzles arranged side by side rotatably on a rotatable table and an inter-nozzle control unit for adjusting the inter-nozzle angle measured between two lines obtained by projecting the radiation center lines of the nozzles onto a horizontal plane. Each nozzle has a deflector which is positioned in front of the nozzle during the very short range mode. Each deflector has a side cover which prevents water having passed through the deflector from excessively spreading sideways. The inter-nozzle angle and the water pressure are adjusted in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern in any range. Thus, the double-nozzle deluge gun can be controlled in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern having an appropriate width in any range.

摘要： An anti-disaster system for receiving terminal data in response to the sequential calling of the terminals which is achieved by designating addresses from a receiver and for performing alarming or the like. Each of the terminals has an interrupt transmission section for transmitting a break signal which invalidates a terminal response signal on a timing when the terminal response signal to the receiver is transmitted when an abnormality is detected to notify generation of an interrupt. The receiver includes an interrupt detection section for detecting an interrupt of a terminal when it receives the break signal at a timing when the terminal response signal is received, and a calling control section for specifying the terminal in which abnormality data is detected, the specification being achieved by transmitting the calling signals for interrupt confirmation to the terminals when an interrupt detection output is obtained from said interrupt signal detection section to allow the terminal to transmit the terminal response signal containing an interrupt level signal which indicates the cause of generation of the interrupt and by performing sequential group calling of the terminals on the basis of the order of priority of the interrupt level signal. Consequently, when urgent data is detected at the terminal end, terminal data can be received quickly independently of the sequential calling and generation of an abnormality can be determined.

摘要： The present invention relates to an improvement of an ionizing smoke sensor having one radiation source and a two chambered structure consisting of an internal ionization chamber housing an internal electrode having a radiation source and defined by an intermediate electrode, and an external chamber where smoke can flow in, defined by an external electrode and irradiated from the radiation source through an opening in the intermediate electrode. Hitherto, in an ionizing smoke sensor having one radiation source and a two chambered structure, there has been a problem in that the giving of misinformation and noinformation occur when a little amount of thread, moisture or dust invades or a current of air flows an internal ionization chamber through an opening and an external ionization chamber. In addition, the electric field in the internal ionization chamber loses its homogeneity because of the opening, hence V-I characteristics preferable for the internal ionization chamber can not be obtained. Furthermore, stable V-I characteristics can not be obtained since hardly any smoke can hardly flow into the internal ionization chamber because of the mesh structure. In the ionizing smoke sensor of the present invention, the above described problems are solved by forming the opening part in the intermediate electrode with a mesh structure having a rate of porosity more than or equal to 50%.

摘要： By using the ratio of the G component to the R component G/R, or the ratio of the B component to the R component B/R, from a television monitor image, and referring to a conversion table for converting to distribution temperature, a surface temperature of a flame is found for each pixel. An area in which luminance signals included in an image of a surveillance area exceed a prescribed level is sampled as a flame outline, and at least the distribution temperature of a sampled flame region is detected, and distance to a radiant energy source is measured. The amount of radiant energy from the radiant energy source is estimated by computation, based on the sampled flame area and its distribution temperature and the distance to the source of radiant energy. The system is provided with a fire image recognition section for recognizing a fire from radiant energy itself and from change in radiant energy over time and outputting fire detection information and an intruder entity recognition section which, from monitor images from the same camera, recognizes an intruder entity and outputs burglary detection information. Processing modes are provided enabling fire and/or intruder entity image processing to be selected. If abnormality detection information is received using fire image or intruder entity recognition processing, a pre-alarm is outputted in the central monitor room, and also the monitor image in the central monitor room is switched to the image of the location where the abnormality has been detected.

摘要： First sensors measure physical quantities correlated with the heat release value of a fire source, and second sensors measure physical quantities correlated with the amount of the product of burning. At least a pair of one first sensor and one second sensor are arranged in a zone to be monitored. A first threshold of high sensitivity and a second threshold of low sensitivity are set at the first sensors. A third threshold is set at the second sensors. A pre-alarm is given only when the level of signals from the second sensors exceeds the third threshold. A fire alarm is given when the level of the signals from the second sensors exceeds the third threshold and when the level of signals from the first sensors exceeds the first threshold. The outputs from a plurality of such sensors detecting different objects, such as heat and smoke, are processed in the manner in which these outputs are combined together to reliably detect fires and to give a fire alarm. It is possible to improve the accuracy of detecting fires, and to reduce the incidence of false alarms.
