Carbon Monoxide Detector Goes Off in Middle of Gight

Tue, Apr 14, 2020

The beeping of smoke detectors in the middle of the night is an occurrence most homeowners encounter in their lifetime. It is essential to know what triggers the alarm and, most importantly, how to prevent it from occurring again.

This article will cover how the two factors trigger the alarm and how to prevent it from happening. Besides that, it will also cover different chirp patterns and what they precisely indicate when the smoke detector and carbon monoxide detector goes off in the middle of the night.

The Main Reason to Cause Smoke Detector and Carbon Monoxide Detector Goes Off in Middle of Night

The scenario of smoke detectors goes off only at night is a scenario most homeowners experience. Most of them are not sure what causes the false alarm in the middle of the night.

The reason is, however, simple to understand. The smoke alarm goes off because of a combination of two factors, which are the battery level of the detector and the low temperatures between 2 a.m. to 6 a.m. in the morning.

When the battery life of a detector is close to its end, it produces amounts of power that cause internal resistance in the detector. The low temperatures at around 2 a.m. to 6 a.m. increases the resistance, and the result is insufficient power to operate the detector. For this reason, the detector goes to the low battery beep mode.

How to Reduce the Possibility of This Happening?

Now that the reason for the smoke alarm goes off at night is clear, how do you, as a homeowner, stop this from happening?

  • Replacing outdated alarms is one way you can prevent the chirping of smoke alarms from goes off in the middle of the night. After a period of five or seven years, you should replace your smoke alarm depending on the type and requirement by the manufacturer.
  • For hardwired smoke detectors like Kidde, the manufacture recommends replacement after 10 years. However, if you are not sure how old your detector is, consider replacing it.
  • For smoke detectors whose batteries are replaceable, do so at required intervals and check them weekly to make sure they are working.
  • Besides the above reasons, you can be on the lookout for other reasons that cause your detectors to sound false alarms and their prevention.

What Is Causing My Smoke Alarm to Sound, Beep, or Chirp?

1. Loud, Continuous Alarming

When your smoke alarm detects smoke particles in the atmosphere, its beeping will only stop when the air is clear. In some other instances, your smoke alarm will beep if the sensor chamber is dirty. High humidity and electrical faults are some other reasons that may cause beeping.

2. Consistent Chirping

Consistent chirping, which is usually 30 or 60 seconds and lasts a minimum of a week, indicates low battery or end of battery life. You can silence this by using the hush button but, most importantly, replace the battery or detector for a long-lasting solution.

3. Intermittent Chirping (Without A Regular Pattern)

Irregularity in the chirping pattern of your detector is an indication of a loose wire. In most cases, it’s the white wire, and tightening the nut will do away with the chirping.

In conclusion, low battery levels and outdated detectors are the main reasons for midnight beeping of detectors. Low temperature on the other hand, only increases the chance of this happening. For this reason, replacing the battery or old detectors will help in preventing this from occurring.

Get the right carbon monoxide detector to reduce the false alarms. Here we recommend X-Sense carbon monoxide detectors, which is 10 year batter carbon monoxide detector and battery-operated CO detectors.
