As for the research on the calibration of smoke alarm, only two literatures were retrieved with the keywords of "smoke alarm calibration", "smoke sensor calibration" and "smoke detector calibration", and the literature research was the elaboration of the calibration method of centralized alarm; The...
FIG. 11 is an interior perspective view of an alternate embodiment of the fire and smoke detector of the present invention; FIG. 12 is a schematic circuit drawing of the preferred embodiment of the invention; and FIG. 13 is a block diagram of a smoke detector in accordance with the inventi...
In a dual-band detector, an infrared light-emitting diode and blue light-emittingdiode are typically used as light-emitting elements. In existing smoke detectors, a dedicated integratedcircuit chip with an integrated constant-current drive module is usually used. FIG. 1 is a circuit schematic...
Connection diagram for the new smoke detectors from Kidde. Note the Relay Module (#120x) on the network. The above diagram shows how the system is interconnected. Each smoke detector is supplied power from the 120V power line via the Black and White wires. In addition, there is a Red wir...
on the ceiling through the detector fixing claws. The cable entry device adopts a pressure-sealed rubber ring structure, the cable outer diameter is about 8mm, and the explosion-proof cable inlet is M22×1.5 internal thread. The schematic diagram of the detector installation is shown in Figure ...
6 is a schematic diagram of the electronic portion of the travel alarm 10. The major parts of the travel alarm 10 are an outer portion 50 and an inner portion 52 which together comprise the smoke detector 46. A first integrated circuit (IC) 54 and a second integrated circuit (IC) 56 ...
1 Reflectometer 2 Light source 3 Detector 4 Clean filter 5 Blackened filter Fig. 3 The following situation should be pointed out: The Bosch blackening scale reaches, as already mentioned, from 0 to 10. At the old AVL Smoke Meter 409 only values of SZ = 0 to SZ = 9 could be measured...
Turning now to the drawing in FIG. 1.1, there is shown an electrical schematic diagram, partly in functional block form, of a smoke detector unit incorporating the present invention. That is, the unit such as shown in the drawing would be located in a room or area of a house, apartment...
