Feature
1.LED light flash
2. Permanent carbon monoxide sensor
3. The alarm sound pattern is four short alarm beeps. The red LED will flash while in alarm mode
4. One ‘chirp’ every 30 seconds is an indication that the battery is low (need replacement) (green LED still flashes once every 30 seconds) or the unit is malfunctioning ( green LED is out).
5. Aarm memory feature: if the unit ever alarms, pressing the button, green LED well flashes once every second for one minute and the peak alarm level will indicate on the LCD.
6. Test/Reset button to test the unit electronics and verifies
proper unit operational and reset the unit during CO alarm.
7. Green and red LED lights that indicate normal operation and alarm status
8. 3 digits LCD displayer is optional. ‘Err’ on the LCD to indicate the unit is malfuntioning. ‘Lb’ on the LCD to indicate it low battery and need replacement. ‘999ppm’ on the LCD to indicate CO level over 999ppm. If the CO leakage is less than 999ppm but over 30ppm, it would show its actual concentration.
9. Blue back light will be lighted when pressing the test button or alarming.
10. The unit will sound ‘chirp’ and red LED flashes once as power up.
11. Power saving feature: the alarm sound pattern is 4 beeps every 5 seconds for the first 4 minutes. In 4 minutes, it will change to 4 beeps every minute to save the battery.
