The lower 50 % of the scenario swings away to reveal the fresh new CO detector and you can abattery owner you to definitely caters around three AA-dimensions alkaline batteries. (The brand new unitcomes which have around three Energizer E91 electric batteries that will be best for on the 12 months ofoperation.) Left of one’s batteries ‘s the changeable plug-for the CO sensormodule. On visibility of carbon monoxide, thesensor acts as an electric battery and creates a voltage proportional so you’re able to new COconcentration. The brand new alarm productivity try canned by a good microprocessor hence drivesthe digital display and you will determines when you should stimulate brand new aural and you can graphic alarmsbased for the quantity and you will time of observed CO.
If pressed when you’re theunit are surprising, brand new key often quiet (“hush”) the newest security for aperiod of your time you to depends on the new CO quantity – 12 times at ten PPM, onehour on twenty five PPM, 6 times during the fifty PPM, cuatro minutes in the 70 PPM
