THE USE OF ALARM CONTROLLER
THE MULTI- POINT MONITORING AND ALARM CONTROLLER IS USED TO DETECT THE CONTENT OF COMBUSTIBLE GAS OR LIQUID VAPOR WITHIN THE LOWER LIMIT OF EXPLOSION IN AIR. IT CAN CARRY MULTIPLE DETECTION PROBES AND CENTRALIZE MULTI-POINT CONTROL AT THE SAME TIME.
THE PRINCIPAL OF ALARM CONTROLLER
THE SYSTEM USES MICROPROCESSOR AS CONTROL UNIT, WHICH HAS HIGH SENSITIVITY AND RESPONSE SPEED. WHEN THE CONCENTRATION OF FLAMMABLE GASES IN THE ENVIRONMENT REACHES OR EXCEEDS THE PRESET ALARM VALUE, THE CONTROLLER IMMEDIATELY SENDS OUT SOUND AND LIGHT ALARM, AND DRIVES EXHAUST AIR OR OTHER PERIPHERAL ACTIONS TO PREVENT EXPLOSION AND FIRE ACCIDENTS, SO AS TO PROTECT LIFE.
