Allocation: double-function sensor fits for gas and carbon monoxide.

Checking gas: poisonous gas (such as natural gas, liquefied gas and city gas(H2) )and carbon monoxide

(1)When the announciator is connected with the electricity supply and the green light flashing is stopped, the announciator is in the checking station. The second light is one double-color light. When the double-color light keeps yellow for 60 seconds, it is in the  carbon monoxide checking station. Then the double-color light changes and keeps red for 90 seconds , and at this time the announciator is in the poisonous-gas checking station. This two colors keeps in turn. The third light (a red one) will flashing and the announciator will alarming when carbon monoxide and flammable gas is checked with the dangerous consistency.  when there is leaking gas with the dangerous consistency, the red light will flashing and the announciator will send out the alarming “di-di-di”sound.

（3）Alarming-error hinting function is provided, which is used for changing and repairing, and is used for the leaking-out alarming, too.

(4) MCU-controlling function is provided, which is used for the stable temperature between -40 to 80.

(5) The quoted-price provided is for the basic one, according to the single-use type. It can be used together with the mainframe, which can be used for the cross-network in the area, or have the alarming sent to the pointed telephone.

Then at the same time of alarming, the ventilator or exhaust-fan will work automatically, which can be used for the harmful gas to be pumped outside. What’s more, the electromagnetic valve in the gas pipeline will be turned off, which can be used for the gas to be interdicted. According to the adding deployment, the price for this part will be counted separately.
