The product is a smart combustible gas detector with microprocessor control.When trigger the gas detector,it will alarm with build-in siren.This detector adopt semiconductor sensor which is stable and reliable.It keeps the place safe from the threats of combustible gas (such as liquefied petroleum gas, natural gas,methane, etc.)Features:High reliable semiconductor method Power supply from AC 90V-240V Intelligent microprocessor controloperation:Connect the detector to 90V-240V power,the red indicator light will light up,at the same time,the red indicator light flashing,and detector start preheating for 3 minutes.When the gas concentration is over 2500PPM,the buzzer will make a continue sound as"Di Di Di"and the red indication light will flash at the same time.Please confirm the induced gas is heavier than air,or lighter than air.the gas is heavier than air.All wires installation must accord with the national and local effective laws and criteria.Specification:1. AV voltage:AC 90V-240V 50-60Hz2. Working temperature:0-50℃3. Environment Humility:10%-95%4. Alarm Density:2500PPM(±1500PPM)5. Alarm time:keep alarming after over 2500PPM6.
