CO Alarm Test Kit (CO-Test) for Testing of Carbon Monoxide Detectors

Carbon Monoxide (CO) Alarm Test Kit (1 test per kit)

Test to be certain the CO alarm is properly sensing the existence of carbon monoxide (CO). The test/reset button on your alarm will tell you that the buzzer operates, but how do you know for sure if the sensor will actually detect carbon monoxide gas? For peace of mind, this test kit will let you know for sure. Safe, fast, reliable and easy to use.


  • Pre-scored glass ampoule filled with actual concentrated Carbon Monoxide Gas (not enough to be harmful)
  • Polyethylene bag
  • Bag tie


1. Place the alarm and glass ampoule inside the polyethylene bag provided. You may need to use an extension cord. Allow at least 4 minutes for the alarm to warm up.

2. Mash excess air out of the bag. Using the twist tie, make sure that the bag is sealed securely around the power cord or otherwise.

3. Snap the ampoule inside the bag by grasping both ends and breaking it in the middle. Be careful not to puncture the plastic bag.

4. The carbon monoxide gas inside the bag should take less than 10 to 20 minutes to activate the alarm.

5. If the alarm does not sound within 20 minutes, it may not be effective in detecting carbon monoxide gas.

6. Dispose of the glass ampoule and plastic bag care­fully after the test is completed.

NOTE: The test ampoule contains a small amount of concentrated carbon monoxide gas, but not enough to be dangerous if accidentally released into room air. Keep out of reach of children.
