摘要： A light emitter (5) projects a light beam into a monitor area (6), and a light receiver (7) is arranged so that it does not receive light directly but only when diffused by fine particles, such as dust, or smoke which enter the monitor area eg via pump (62). The light receiver output is amplified at (8) and a counter (14) counts number of pulses in the amplifier output in successive units of time. A computer (CPU) computes the average value or an integrated value of the amplifier output for each unit of time, and determines the level of contamination from the count value and the level of fire from the average or integrated value. Alternatively (fig. 30) the frequency distribution of pulses in the amplifier output may be computed and compared with reference distributions representing the pressure of fine particles and of smoke. The drive (4) for the emitter may be switched between pulsed and continuous operation.

CONSTITUTION:Thermal sensors, 4, 5 and smoke sensors 6, 7 as fire sensors are connected to a receiver 1. The thermal sensors 4, 5 are provided in each monitoring area which is divided by a fire prevenint/smoke preventing device, and transmit a fire detecting signal to a relay 3 when a detected temperature exceeds a threshold value. The smoke sensors 6, 7 detect the concentration of smoke due to the generation of a fire, and transmit a fire detecting signal when the smoke concentration exceeds a threshold value. Also, a testing unit 9 is provided on the smoke sensors 6, 7, and a test by a test LED is performed, and when it is found out that a failure takes place, a failure signal is outputted. In addition, smoke discharging devices 23, 24 are provided. By this method, even when one of the smoke sensors 6, 7 fails, the fire preventing/smoke preventing device and smoke discharging devices 23, 24 can be operated.

摘要： PURPOSE:To provide an alarm for fire protection equipment which makes an alarming before the closure thereof to secure safety in the perimeter thereof. CONSTITUTION:When a controller 11 receives a starting signal from a compound panel or the like provided at a desaster prevention center or the like, firstly, a closure message is announced by a vocal synthesization to alarm of the closure of a fire protection door 10. When fixed time passes thereafter, a control signal is outputted to a release 12 to release the retaining of the fire protection door. As a result. the fire protection door 10 is moved to a closure position. The closing operation of the fire protection door 10 is accomplished after the closure message is heard and allows the people in the perimeter of the fire protection door 10 to avoid danger in the perimeter caused by a sudden closure, thereby enabling the closing of the door safely.
