Polon Alfa Top-40 Multi-Sensor Heat and Flame Detector

Polon Alfa Top-40 Multi-Sensor Heat and Flame Detector, the heat sensor is a thermistor which reacts to the rise of temperature occurring during the first stage of a fire. At the time of the simultaneous detection of both the increase in temperature and flame, the detector transmits an alarm signal to the fire alarm control panel.
The use of two sensors eliminates the possibility of false alarms and allows the use of detectors in areas where due to the amount of dust or dirt that was not previously possible. The TOP-40 detectors can operate in lines/loops of the IGNIS 1000 or on the sideline of ADC-4001M adapter in POLON 4000 fire alarm control panels.
