摘要： When data of EEPROM storing set data such as interlocking data representing the interlocking relation between a fire sensor and an appliance to be controlled, correspondence data between the address of each terminal and an installation position of each terminal, display data displayed at a display portion of a fire receiver, reception function data representing the functions of the fire receiver, etc, are updated, the fire receiver of the present invention uses a memory pack which consists of an IC card, etc, and can be removably connected to the fire receiver, connects the memory pack storing data for updating the data to the receiver and reads the data and writes it to the EEPROM. Further, the set data before updating, that are stored in the EEPROM, are read into the memory pack, and this memory pack is carried to a service center, etc, so that set data for updating can be generated in consideration of the set data before updating, and are similarly written into the EEPROM through the memory pack. In this way, even those who have no knowledge on the ROM, that is, electronic circuits, can appropriately update the set data. Moreover, the updating operation is easy. The present invention provides such a fire alarm receiver and a fire alarm system.

摘要： A smoke detector includes: a casing; a first light emitting unit; a second light emitting unit; and a light receiving unit. A second scattering angle that is an angle between the reception axis of the light receiving unit and a second extension extending from an intersection of the second emission axis and the reception axis in a direction away from the second light emitting unit is larger than a first scattering angle that is an angle between the reception axis of the light receiving unit and a first extension extending from an intersection of the first emission axis and the reception axis in a direction away from the first light emitting unit.

摘要： Problems:
There is a technology using the reflected light which is emitted from the light-emitting element and reflects without being absorbed in the inside of the optical bench, in order to detect whether the light-emitting element and the light-receiving element normally function. In this case, they do not normally function when there is either too little or too much reflected light in the inside of the optical bench. It is therefore an object of the present invention to achieve a suitable amount of reflected light inside the optical bench.
Means for solving the problems:
A light-receiving element 93 and a first light-emitting element 91 are disposed in a position in which the light-receiving element 93 receives forward-scattered light produced when smoke in the smoke detection part 10 is irradiated with first irradiation light emitted from the first light-emitting element 91. A secondary reflecting plate 716 is provided on a side of the first light-emitting element 91 inside the peripheral wall. The secondary reflecting plate 716 is configured to form secondary reflected light when the smoke detection part 10 without smoke is irradiated with the first irradiation light. The secondary reflecting plate 716 receives primary reflected light resulting from reflection of the first irradiation light from the peripheral wall and reflects the primary reflected light, and then allows the formed secondary reflected light to enter the light-receiving element 93.

摘要： A fire monitoring system includes a smoke detector, a first correction unit obtaining a first corrected value by multiplying a difference value between a reference value and a detection value by a first correction coefficient, a first conversion unit converting the first corrected value into a first smoke density, and a fire determination unit determining occurrence of a fire event based on the first smoke density. The first correction coefficient is set on an increase side corresponding to an increase in a rate of change of the reference value to an initial reference value, and an upper limit value is set for the first correction coefficient.

摘要： A sprinkler head employing balls for a heat-sensitive disassembling unit is provided, in which the time period from when a fusible alloy starts to melt until when the sprinkler head is activated is shortened. A sprinkler head includes a frame having a stepped portion projecting inward. The stepped portion has an upper inclined surface provided at the inner-peripheral upper edge thereof and with which balls come into contact, and a guide part provided at the inner-peripheral lower edge thereof and that allows any of the balls that is displaced from the upper inclined surface to move downward from the stepped portion. When a fusible alloy melts, the ball displaced from the upper inclined surface moves along the guide part and is quickly released to the outside of the frame. Hence, the time period from when the fusible alloy starts to melt until when the sprinkler head is activated is shortened.

摘要： A fire control panel in which an address map window (30), in which terminal device control switches (31) each indicating an address number (AD) of a terminal device are arranged in a matrix shape, is displayed on a display/operation unit (2). In addition, each of the terminal device control switches (31) corresponding to a status stored in a terminal database (DB) is displayed in a display mode that differs depending on each status. Accordingly, it is possible to grasp status information on a large number of terminal devices at a glance through one screen.
