Carbon Monoxide Detector


An estimated 400 people die from carbon monoxide poisoning associated with home fuel-burning heat equipment every year in US (Minnesota dept of health stats). It is small figure but is enough for you to worry, if you are using a fuel-burning fire equipment. While heating equipment is a must have and essential part of US houses, safety of its inhabitants is also of paramount importance. Therefore it is a must to have a carbon monoxide detector at every house.

What is Carbon Monoxide?

Carbon Monoxide (CO) is colorless, odorless and tasteless poisonous gas. It often mixes with other gases present in the house and does produce an odor, but people don’t recognize the smell and inhale the poison without knowing they are inhaling CO.

Carbon Monoxide is a killer gas. It displaces oxygen form the blood and deny the heart, brain and every vital organs of Oxygen and essential for our survival. This is a silent killer and can make you unconscious and suffocate you in minutes without any warnings or signs. Which can lead to death. Children and the elderly people are the most prime victim of this unseen killer.

What Are The Common Sources Of Carbon Monoxide Poisoning In Houses?

It is very important to know the places which can cause the carbon monoxide poisoning. This makes it easy to mark the places for installing carbon monoxide detectors. The most common places which can cause carbon monoxide leakage are:

  1. Furnaces
  2. Dryer vent
  3. Chimney
  4. Water heaters
  5. Fireplaces
  6. Gas stoves and ovens
  7. Gas from house car and other vehicles
  8. Grills, power tools, garden equipment, power generators etc.
  9. Wooden stoves
  10. Cigarette smoking at home

Why Is Carbon Monoxide Detector Necessary For Every Home?

Carbon Monoxide is the silent killer of 400 people every year in America. These people are killed in the safe vicinity of their home. Sometimes the whole family is at risk. So it is really important and a duty of every house owner to install a carbon monoxide detector at their home. For the safety of them and their loved ones. A good quality CO detector identifies the CO level and warns the inhabitants of the poisoning and provides them escape form certain harm. So for the security and health of the family a carbon monoxide detector in every house is a must.

Which Are The Best Places For Installing The Carbon Monoxide Detector?

The carbon monoxide detector should be placed in every level or floor of the house. It should also be placed in every bedroom along with the smoke alarm system.

Kidde Nighthawk AC Plug-in Operated Carbon Monoxide Alarm

Protect your family from the dangers of carbon monoxide (CO) exposure with the Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display. The Nighthawk is an easy-to-install unit that provides reliable protection against the dangers of CO.

The digital readout of the Kidde Plug-In Digital Carbon Monoxide Alarm with 9-Volt Backup continuously displays carbon monoxide levels from 30 to 999 parts per million (PPM) and will sound an 85 dB alarm when dangerous levels are reached. The carbon monoxide level sensed is continuously displayed and updated every 15 seconds, and the peak level memory shows the highest level of carbon monoxide present since the last time the unit was reset or unplugged. Protection continues during power outages thanks to a 9-volt battery backup.

Carbon Monoxide Detector

  • Peak Level Button – Displays the peak CO level recorded by the alarm since it was last reset or unplugged
  • Test Button Functions – Tests the unit for proper operation and resets the Carbon Monoxide alarm
  • LED Operation – Blinking dot in lower right corner of display denotes normal operation
  • Ten years after the initial power up, this alarm will “beep” two times every 30 seconds to indicate that it is time to replace the alarm.
  • NOTE: This CO alarm is not battery operated. However, these alarms are equipped with 9 volt battery backup – the 9 volt battery is to supply short term back-up during a power outage.

Honeywell Ademco 5800CO Wireless CO Detector

The 5800CO is a 3V battery powered wireless carbon monoxide (CO) detector intended for use with Honeywell alarm systems that support 5800 Series wireless devices. It provides early warning when its electrochemical sensing technology measures carbon monoxide levels in the air. The 5800CO is specifically designed for system operation and is fully listed to UL 2075 as a system supervised detector.* It contains a piezoelectric horn which generates the ANSI S3.41 temporal 4 pattern in an alarm condition.

The detector consists of an electrochemical carbon monoxide sensor assembly coupled with a wireless transmitter. The transmitter can send alarm, trouble, end-of-life, tamper and low battery condition messages to the alarm panel. Since there are no holes to drill or wires to run, you can preserve the beauty of the home or building while protecting its occupants from harmful carbon monoxide gas. The 5800CO is an ideal carbon monoxide detector for difficult to wire locations, applications where room aesthetics are critical or where hazardous materials exist.
