PLC GENERATE COMMAND TO START FOAM P/Ps

WORKING PRINCIPLE OF HEAT DETECTOR

* HEAT DETECTOR SENSES HEAT OR RATE OF RISE IN THE AIR TEMPARATURE , BASICALLY IT CONSIST THERMISTER WHICH WORK ON NEGATIVE TEMP.

COFFICIENT OF RESISTENCE. WHEN TEMP. INCREASES, RESISTENCE DECREASES IN

THE DETECTER SO IT DRAW MORE CURRENT , WHEN INCREASE IN THE

CURRENT REACH THE PREDETERMINED VALUE THE DETECTOR GIVES THE

ALARM. .

WORKING PRINCIPLE OF OPTICAL SENSOR

* IT CONSIST INFRARED SOURCE WITH PEAK SPECTRAL EMISSION 880 NM. THE LED SOURCE AND THE DETECTOR ARE PLACED AT AN SPECTRALLY MATCHED ANGLE . WHEN NO SMOKE THE LIGHT

REFLECTED FROM CHAMBER WHICH SHOW SMALL CURRENT. IN CASE OF SMOKE DUE

TO SCATTERING OF LIGHT CURRENT GENERATION IS MORE, DUE TO THIS

VOLTAGE LEVEL REACH THE PRESET VOLTAGE VALUE CAUSES FIRE ALARM.
