Operating Characteristics:
اولین, after the battery alarm Shanghai. Will issue a sound, but also quickly flashed red, LED display 888 ppm, indicating that the battery is installed correctly, the green light flashes about every 30 ثانیه, the display exterminate, when the concentration exceeds 30 ppm display lights
دومین, press the test button, the alarm will sound, indicating that carbon monoxide alarm is energized and the line? Rice Bru bald #?
سوم, when the low battery alarm every 30 seconds will send a sound, or LED display is to remind you to replace the battery LB
چهارم, after the alarm alarm will write down the value of the last alarm, then press the button that value will be displayed, the green light will flash one second once again the key to return to the reset state.
پنجم, an alarm can detect only a 25 square meter room below, due to carbon monoxide gas light, the alarm installed in the ceiling or wall of the room can be high.
Carbon Monoxide Alarm Features:
1. electrochemical sensors, sensor life of up to five years.
2.3 صفحه نمایش ال سی دی.
3. Reset, Test function: تست / reset button, the test circuit parts and reset the alarm when the alarm test button: Press a few seconds an alarm sound shows alarm properly.
4. مصرف برق کم: 3 باتری های AA (4.5V), Standby can work for more than two years, if alkaline batteries work longer.
5. Static current: <80Ua, 200Ua (when LCD is lit)
Alarm current: <85mA
6. High-Performance Microcontrollers extracted from accurate detection and algorithms can detect concentrations as low as a few PPM.
7. Alarm concentration / زمان: according to EN50291 European or American standard design, CO gas (50 ppm --- 60 ~ 90 دقایق ; 100 ppm --- 10 ~ 40 دقایق; 300 ppm --- کمتر از 3 دقایق).
8. Static indication: red LED flashes once every 30 ثانیه.
9. Low-voltage alarm function: low voltage alarm to remind you to replace the battery promptly issued a "squirt" sound every 30 ثانیه, صفحه نمایش ال سی دی (Lb).
10. زنگ خطر. هشدار: 3M at high decibel alarm sound (> 85دسی بل), frequency of about 3KHz, the red LED flashes quickly.
