Carbon monoxide detector with LCD displayer

-Loud 85 decibel alarm.

- Permanent carbon monoxide sensor.

- Powered by 9V batteries.

- The alarm sound pattern is four short alarm beeps. The red LED will flash while in alarm mode.

-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.).

- Alarm memory feature: If the unit ever alarms, pressing the button, red LED will flashes once every second for one minutes and the peak alarm level will indicate on the LCD.

- Test/Reset button to test the unit electronics and verifies proper unit operational and reset the unit during CO alarm.

-Green and red LED lights that indicate normal operation and alarm status.

-Yellow LED light that indicate the sensor fault status.

- 3 digits LCD displayer is optional. ‘Err' on the LCD to indicate the unit is malfunctioning. ‘Lo' 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.

- The unit will sound ‘chirp' and red LED flashes once as power up.

- 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.

Green LED: The green LED flashes every 30 seconds to indicate the unit is operating properly.

Red LED: When a dangerous level of carbon monoxide is detected the red LED will flashes and the alarm pattern will sound.

Yellow LED: light that indicate the sensor fault status.

The CARBON MONOXIDE (CO) alarm monitors the air for the presence of CO. The alarm will sound and be accompanied by the flashing red LED light when there are high levels of CO present.

CAUTION: This alarm will only indicate the presence of monoxide at the sensor. Carbon monoxide gas may present at other area.
