    摘要: A fire sensor comprising a baseplate (101), a temperature detecting element (102), and a protective case (103). The baseplate (101) has an outside surface which serves as a heat sensing surface which is exposed to a hot airflow generated by a fire. The temperature detecting element (102) thermally contacts with the inside surface of the baseplate (101) to detect the temperature of the baseplate (101). The protective case (103) contacts with the radially outer portion of the inside surface of the baseplate (101) to form a hermetically sealed space between itself and the baseplate (101). The temperature detecting element (102) is confined within the hermetically sealed space. The baseplate (101) has the temperature detecting element (102) in approximately the central portion of the inside surface thereof and also has a shape and a material which meet the condition that the product of the thickness and heat conductivity of the baseplate (101) is 1.1 × 10 -4 (W/K) or less.

    摘要: A flame detection circuit and method using a flame probe (1,3), across which an alternating voltage is applied, is described. The means for applying an alternating voltage comprises a pair of terminals (5,17) for connection across the two rails of an A.C. supply. A pair of resistors (19,21) are connected across the terminals, with an A.C. current path being provided between the node between the resistors (19,21) and the flame probe (1,3), the resistance of each of the resistors (19,21) being equal.

    摘要: Es wird Licht durch zwei oder mehr wärmeempfindliche Lichtleitfasern geleitet, die unmittelbar unter, in oder auf dem Strohdach angebrackt sind. Es wird Feuer gemeldet, wenn sich die Lichtleitung durch mindestens zwei Fasern ändert, während ein Fehler gemeldet wird, wenn sich die Lichtleitung durch nur eine der Fasern ändert.
    Verringerte Lichtleitung durch eine Faser wird dadurch nachgewiesen, daß Licht mit einem rampenförmigen Intensitätsverlauf in das eine Ende der Faser eingestrahlt wird und die Zeit gemessen wird, die vom Start der Rampe vergeht, bis Licht einer im voraus festgelegten Intensität aus dem anderen Ende der Faser empfangen wird.

    摘要: A fire sensor apparatus is provided with a fire sensor which has a built-in microcomputer and in which fire detection levels can be varied according to changes in environmental conditions (noise level) in the area in which it is installed. A signal from a sensor (1) is digitized in an A-D converter (3) and is input to a comparator (12). A CPU (5) determines the current time from a clock (4) and removes from a memory accumulated data on operating leveland noise level at the corresponding time in the past. The CPU (5) sets an operating level for the time concerned by executing a predetermined calculation, and compares this operating level with the signal from the sensor (1). An abnormal state is indicated at (14) or the accumulated data is renewed, according to the result of the comparison. Thus it is possible to set an appropriate operating level according to changes in noise level, and fire detection can be effected with a suitable detection sensitivity.
