HEAT AND SMOKE DETECTOR WITH THE VISUAL SIGNALING DEVICE TSF
The heat and smoke detector is intended for detecting fires in their early phase. The detector has two sensors: heat and smoke. The application of two types of a sensor allows to detect all types of fires quickly and with certainty. Additionally, the detector has the flashing visual signalling device built-in due to which the detector fire alarm is visible from a large distance. The two-sensor detector operates within the AWEX fire alarm system. The element can be installed on the detection loops or stub detection circuits.
The two-sensor smoke and heat detector is equipped with two sensors for fire detection. The smoke detection takes place in a detection chamber equipped with photoelectric diodes. Smoke goes to the chamber during fire. The particles of smoke reflect the light emitted by light emitting diodes which causes that an IR diode receives the signal and transmits it to a microprocessor.
The heat detection takes place by means of 4-thermistor temperature measurement system. A fire alarm is generated when temperature limit is achieved, or in case of quick increase of temperature. Then, it recognises the type of alarm and transmits it to the supervisory line, and to the control unit.
