Test/Silence Button
The Test/Silence button is used to test the unit's electronics and to silence the unit during an alarm. When testing the alarm weekly, press and hold the test button and you will hear a short beep, indicating that the alarm has entered the test mode.
XCO01: You should first wake up your alarm by pressing the test button; once the alarm has woken up, the LCD display will activate, then press the test button again until you hear a short beep, indicating that the alarm has entered the test mode. Please refer to the "Alarm Testing" section for further information. The alarm goes back to the standby mode after testing. To save power, the alarm is designed to automatically turn off the LCD display if there has been no operation for 5 minutes.
XCO1-R: Short press the test button and you will hear a short beep, indicating that the alarm has entered the test mode.
NOTE: After a test has begun, the alarm will sound and the LED indicator will flash red. This does not indicate that CO is present. If you press the test button during an alarm state, the unit will enter the silence mode.
CO Alarm Levels
This X-Sense carbon monoxide alarm is programmed to sound an alarm at the following CO concentrations within the time periods listed:
70 ppm for 60-240 minutes,
150 ppm for 10-50 minutes,
and 400 ppm for 4-15 minutes.
When CO is detected and the alarm sounds, the CO concentration will be displayed on the LCD and a blue backlight will be lit. The LED indicator will flash red and the alarm will issue 4 short beeps, repeating the cycle every 5.8 seconds.
CO Concentration and Symptoms
The table below shows the effects of different levels of CO poisoning on the body:
Parts per Million (PPM) | Effects on Adults |
100 | Slight headache, nausea, fatigue (flu-like symptoms). |
200 | Dizziness and headache within 2-3 hours. |
400 | Nausea, frontal headache, drowsiness, confusion and rapid heart rate. Risk to life after over 3 hours of exposure. |
800 | Severe headaches, convulsions, vital organ failures. Death possible within 2-3 hours. |
THIS DEVICE IS DESIGNED TO PROTECT INDIVIDUALS FROM ACUTE EFFECTS OF CARBON MONOXIDE EXPOSURE. IT MAY NOT FULLY SAFEGUARD INDIVIDUALS WITH SPECIFIC MEDICAL CONDITIONS. IF IN DOUBT, CONSULT A MEDICAL PRACTITIONER.
Low-Battery Warning
If the battery voltage is low, the unit will chirp once and the LED indicator will flash yellow every 60 seconds to indicate the need for battery replacement. If you press the test button when there is low battery, the low battery signal will temporarily cease for 10 hours; if you press the test button again, the unit will enter the test mode and then the standby mode.
End-of-Life Indication and Hush Control
Once the maximum lifetime (10 years) is reached, the alarm will deliver 3 beeps and the LED indicator will flash yellow 3 times every 60 seconds. This end-of-life signal can be temporarily silenced for 22 hours by pressing the test button. The end-of-life silence feature can only be used for a total of 30 days. After 30 days, the end-of-life signal cannot be silenced. During this end-of-life hush period, your alarm continues monitoring CO and provides protection as usual. To help identify the date to replace the alarm, write down the date of first operation on the dedicated label on the side of the alarm.
Ideally, a carbon monoxide alarm should be installed in every room containing a fuel-burning appliance, and one in every bedroom. However, if the number of carbon monoxide alarm available is limited, the following guidelines should be considered when choosing the best places to install an alarm(s):
NOTE: Due to the product's unique design and unfixed installation, it is not recommended to install it on a ceiling, as it is prone to falling off and causing injuries to people.
Important Note
Improper location can affect the sensitive electronic components in this alarm. To avoid causing damage to the unit, to provide optimum performance and to prevent unnecessary nuisance alarms, do not locate CO alarms in the following areas:
To Activate the Device
This device is equipped with a battery insulating film to ensure it will not be powered on during transportation before it has shipped from the factory. When installing this product, you will need to pull out the film before powering on and activating the device.
Before use, pull out the battery insulating film from the battery compartment to power on the device. After the device is turned on, the buzzer will beep once, the LCD backlight will light up, and the LED indicator will flash through 8 cycles (yellow/green/red). The device will then enter standby mode.
CONSTANT EXPOSURE TO HIGH OR LOW TEMPERATURES AND HIGH HUMIDITY MAY REDUCE BATTERY LIFE.
Wall Mounting
Installation on a Table
The base of the detector has two feet built into the design that allow it to stand freely on a flat surface.
NOTE: When placing on a shelf, please adhere to the recommended placement as described in "Where to Install."
Be sure to test your CO alarms when you turn them on for the first time. In addition to the weekly test you should perform, it is also recommended to test the alarm after returning from a long trip or vacation.
Type | XC01 | XCO1-R |
Action | Push the test button once to wake up the alarm, and press the test button again when the LCD is on. | Push the test button. |
Device Response | The device beeps 4 times twice, and the LED will flash red. The LCD will display "---," PAS," the peak CO concentration recorded since the previous reset, and finally "0." This indicates that the device is functioning properly. |
NOTE: The test function accurately tests the alarm's CO sensing circuit without the need of testing CO.
The peak CO concentration feature is helpful in identifying if there have been any dangerous CO readings since a peak CO concentration reset.
Each time you push the test button, the LCD displays the peak CO concentration recorded since the previous reset. The peak CO concentration will be displayed for 5 seconds, and then the device will enter standby mode. In the example, 300 ppm was the maximum CO concentration recorded since the unit was last reset.
Peak CO Concentration Reset: During the 5 seconds when the LCD displays the peak CO concentration, press and hold the test button for 3 seconds, the device will beep, the LED will flash green, and the peak CO concentration will be reset with LCD displaying "0."
NOTE: If the carbon monoxide concentration is lower than 30 ppm, it will not be recorded in the peak CO concentration.
Press the test button during an alarm to have the unit enter silence mode. If the CO density still exceed the alarm threshold after 6 minutes, the unit will enter another alarm state. Otherwise, the unit will exit the silence mode after 9 minutes and resume normal operation. If the CO concentration is above 300 ppm, the silence function cannot be enabled.
