How do the DarcSens Work?

For sound alarms:

  • 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, green LED will flashes once every second for one minute and the peak alarm level will indicate on the LCD.

For display:

  • Green and red LED lights that indicate normal operation and alarm status.
  • 3 digits LCD displayer is optional. ‘Err’ on the LCD indicates the unit’s ‘malfunctioning.
  • ‘Lb’ on the LCD to indicate it low battery and need replacement.
  • ‘999ppm” on the LCD indicates CO level is over 999ppm. If the CO leakage is less than 999ppm but over 30ppm, the device will show the actual concentration.

For testing the device:

  • Test/Reset button to test the unit electronics and verify proper unit operation and reset the unit during CO alarm.
  • A blue backlight will be lighted when pressing the test button.
  • The unit will sound “chirp” and red LED flashes once as power-up, with “888” displayed on the LCD for 2 seconds. Then press the test button, the unit will sound 4 beeps every 5 seconds twice with red LED flashes. During the self-test mode, “O00” displays on the LCD for 3 minutes and then enters in normal operation mode.
  • 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.

More about the lights and buttons:

  • 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 flash and the alarm pattern will sound.
  • The CARBON MONOXIDE (CO) alarm monitors the air to determine if there is a 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.

Looks better

More modern and stylish than most detectors so if you need to mount this someplace conspicuous (like in a camper) it's not an eyesore.

Feel Better

Product was exactly what it promised. It loyally stands guard in my basement ready to let me know if there is an issue with carbon dioxide. Easy to install the battery, screen is digital and comes with hardware for wall mounting. It's a keeper.

Works as described

I feel this was a good purchase and would recommend it. I like the display and set up of the device. It was easy to install. I feel a little more safer knowing I have this additional device to protect me from a Carbon Monoxide event should one occur.

Angela Peltier
Good to have in house.

Good to have a carbon monoxide alarm and a fire alarm in your house cause both could kill you while your sleeping. This was easy to install and it gives best places were you should so you need to read instructions.

Harvey E. Page
Great value

very easy to mount and the access to replace the battery is easy. Nice display so you can see that it is working from a distance- the alarm is plenty loud and easy to test and reset. We had our gas heater on in the RV and slept without worrying about CO! Great product!
