4 DESIGN DESCRIPTIONS The DOT-40 detector mechanical design is shown in Fig. 1. The device is equipped with two sensors that detect two fire factors: heat and smoke. Heat is detected by a temperature-sensitive resistor (thermistor) whereas smoke is detected by a special optical module consisting of a light transmitting diode and a receiving one. - Page 5 (generating no smoke). The DOT-40 detector long-lasting operation may result in dust accumulation inside its smoke sensor. After exceeding the self-regulation range due to the smoke sensor contamination progress, the...
