#DEY Household Coal Smoke Detector Carbon Monoxide Detector Alarm Features: 1. Battery-powered carbon monoxide alarm (commonly known as gas alarm), 4.5 battery-powered, controlled by a micro-power CMOS microprocessor. 2. High volume alarm sound output (3 meters directly in front of> 85dB). 3. The use of high sensitivity, high stability, long life zero power consumption electrochemical carbon monoxide sensor, excellent anti-alcohol interference performance (anti-alcoholism). 4. Under normal conditions, the LED indicator flashes once in about 40 seconds; when an alarm is issued, the LED indicator flashes quickly and an alarm sounds. When the carbon monoxide concentration decreases, it returns to the monitoring state. 5. Self-test function, press the test button to test whether the alarm function is normal, it is recommended to test once a week. 6. Anti-battery reverse connection protection function; low battery voltage detection function, when the battery voltage is low, a warning sound will be emitted every minute to indicate that the battery will be exhausted and replace the battery early. 7. Static monitoring is less than 35 microamperes, with extremely low standby power consumption (<0.35 milliwatts); alarm working current is about 20 milliamps. Description: Optional normally open and normally closed contact output (need to be customized) to facilitate connection to control equipment. Installation and battery replacement are very convenient. Independent, household carbon monoxide alarm is used for gas and CO leak detection, and can be installed in kitchens, bathrooms and other places. During the heating period in winter, doors and windows are usually closed tightly, and the gas (carbon monoxide gas) in the air is inconvenient to circulate, which increases unsafe factors. Using household carbon monoxide alarms (gas alarms) can effectively prevent danger from occurring.
