摘要： PURPOSE:To prevent malfunction when an environmental temperature is low and to prevent delayed announcement and lost announcement when the temperature is high by changing an operating temperature rising rate, which goes to be the reference of fire discrimination, in correspondence to the environmental temperature. CONSTITUTION:A signal from a fire phenomenon detecting part FS is read in an RAM2 for work and next, the signal is written to an RAM1 for sensor output level storage as a present sensor output level. When the newest sensor output level is stored in the RAM1, based on the sensor output level in the RAM1, the arithmetic of the temperature rising rate is executed. Next, the oldest sensor output level in the RAM1 is obtained as the environmental temperature and the correspondent operating temperature rising rate is read from an ROM2 for temperature to operation rising rate table storage. Then, the rate is compared with an operating temperature rising rate to have the operated present temperature rising rate as a reference value. When the temperature is over the reference value, a fire signal sending part TX is operated and a fire signal is sent to a receiver RE.

摘要： PURPOSE: To obtain an inexpensive foam extinguisher requiring no mounting work suited to small oil fires by a method wherein, when an automatic valve is opened, a foam solution and extinguishing water flow to a foam generator by a pressure gas to be mixed at a specified ratio and discharged from a nozzle and blown to a net to generate a highly bubbling foam. CONSTITUTION: A foam extinguisher 5 is constituted of a double-structured cylinder body 6, and a circular housing part 7 in the peripheral part is divided in two, i.e., a foam solution tank 9 and an extinguishing water tank 10 by a partition wall 8. When a fire occurs in a storage solution bit 3, a closed type sprinkler head 18 is thermally operated and extinguishing water in a pressure storage chamber 27 of an automatic valve 13 is discharged at the sprinkler head 18. A valve body 25 of an automatic value 13 is pushed up by the pressurized extinguishing water from the extinguishing water tank 10 to mix the foam solution and the extinguishing water with an orifice. The mixed solution is blown to a net 11 for generating a foam from a nozzle 15 through a constant flow valve 14 to be highly foamed and thus, flows into the solution storage bit 3 to be gradually accumulated thereby extinguishing a fire.

摘要： PURPOSE:To allow a supervisor to sufficiently recognize the condition of a place and to execute a suitable processing by displaying the generating place of fire abnormality when the fire abnormality such as fire generation or the existence of the possibility of fire, etc., and displaying also the environmental information of the place. CONSTITUTION:When a time comes to execute the discrimination of a sensor level, the output of a fire phenomenon detecting part FS to be A/D converted is read through an interface IF31 and the output is compared with the fire discriminating level of a RAM33 for fire discriminating level storage. When the sensor level is the fire discriminating level or above, an address code (AC) of itself is read from a ROM32 and usage and dangerous degree are read from a RAM32 for usage and dangerous degree storage and sent from a signal sending part through an interface IF for transmission to a receiver. The spot of the fire is discriminated and the fire block and fire spot are displayed to a display part DP.

摘要： PURPOSE:To minimize the erroneous information, lost information and late information by changing a fire discriminating reference in accordance with the use information of the installation place of a fire sensing device or a fire sensor and executing the suitable fire abnormality judgement. CONSTITUTION:A fire sensor SE1 sends a detecting signal from a fire detecting part FS and the use information set at a dip switch DIP to a receiver RE. The receiver RE to receive this writes the sensor data to show the use into a RAM 12 for storing the use. Next, from a use/action level converting table stored in a ROM 13, an action level corresponding to the use data written in the RAM 12 is read and stored into a RAM 11 for work. Based on the memory contents, a fire discriminating reference is prepared and stored into a RAM 13. Based on the fire discriminating reference stored in the RAM 13, the fire is discriminated.

摘要： PURPOSE:To minimize the erroneous information, lost information and late information by changing a fire discrimination reference in accordance with the risk of the installation place of a fire sensing device or a fire sensor and executing the suitable fire abnormality judgement. CONSTITUTION:A fire sensor SE1 sends a detecting signal from a fire detector FS and the risk information set at a dip switch DIP to a receiver RE. The receiver RE to receive this writes the sensor data to show the risk into a RAM 12 for storing the risk.

摘要： PURPOSE:To surely give an alarm in an early stage, by outputting a signal indicating abnormality when the value obtained by integrating a part higher than a reference function, which gradually rises as the function of time, of the sensor output level with respect to time reaches a prescribed integral value. CONSTITUTION:A sensor output level SLV is sampled at intervals of a prescribed time DELTAt by a sampling means, and a difference SLV-R between the sampled sensor output level higher than a reference function R, which gradually rises as the function of time (t), and the reference function R is integrated at intervals of the time DELTAt by an integrating means. A discriminating means compares the value integrated by the integrating means with a prescribed integral value, and the signal indicating abnormality is outputted when the value integrated by the integrating means reaches the prescribed integral value. Consequently, a fire is stably detected which state the sensor output level rises in at the time of the occurrence of the fire.

摘要： PURPOSE:To eliminate the need for increasing the power source capacity of a receiver so much, to supply a voltage sufficient for a heat type sensor and to improve a reliability by providing a potential change means to change the potential of a connection point of a heat sensitizing element with a resistance for output. CONSTITUTION:A fire detecting part 10 has a heat sensitizing element RS to change a resistance value by an ambient temperature, a resistance R0 for output connected in series with the heat sensitizing element RS, a resistance RT for test provided in parallel with the heat sensitizing element RS and a make contact (a) connected in series with the resistance RT for test. A control part 21, a transistor 24, a relay 25, the make contact (a) and the resistance RT for a test are one example of potential change means to change the potential of a connection point B of the heat sensitizing element RS with the resistance R0 for output. Namely, by making the output P of the control part 21 an 'H', the transistor 24 is turned on, the relay 25 is actuated, the make contact (a) is turned on and the potential of a point B is raised. Thus, the power source capacity of the receiver is not necessary to increase so much and the lowering of the reliability of a test result due to a heater deterioration is not generated.
