Sindee Buchalter, of Towne Realty Group’s Short Hills Office, reported this important information to our team today.
This data could save your life and I hope you will share this with friends, neighbors and relatives.
Sindee wrote “I learned something valuable today and thought that perhaps I am not the only one who did not know this. If you have CO detectors in your home (and that should be everyone), read on.” If you don’t have CO detectors, it is time to buy them and be ready to replace them in 2016.
My carbon monoxide detectors are hardwired into my security system and two of the units started to beep and a green light began to flash today. These units were installed in Nov. 2005 so they are relatively new. I called my contact at the alarm company and was told that the gas sensor in my detectors has reached the end of its life expectancy and all my CO detectors units (I have one on each level) had to be replaced. I had never heard of this happening. I believed that when you installed a CO unit or used a plug in version and tested it occasionally, it was working and protecting you from carbon monoxide.
I did some research on-line and confirmed the following facts:
THE SENSORS IN CARBON MONOXIDE DETECTORS EXPIRE AFTER APPROXIMATELY FIVE YEARS.
The CO sensor itself is considered to be the most likely component to fail, with a limited lifetime of up to 5 years. This is of huge concern as an estimated 50% of all detectors installed in the UK and US are over 5 years old. If your CO alarm is over 5 years old it is strongly recommended that you replace it.
The gas sensors in CO alarms have a limited and indeterminable life span, typically two to five years. The test button on a CO alarm only tests the battery and circuitry system, not the sensor.
CO alarms should be tested with an external source of calibrated test gas, as recommended by the latest version of NFPA 720. Alarms over five years old should be replaced and they should be checked on installation and at least annually during the manufacturers warranty period. Almost all CO detectors do not have replaceable sensors.
On the combination CO and Smoke detectors, you will often see a manufacture date or a replace by date inside the cover on the main board.
On hard wired versions you will get the error light when the sensor fails. (This is what alerted me) although some older units might not have the light. If you got the full 5+ years out of your CO2 sensor, be grateful that it served a full life expectancy, and now REPLACE IT.
Not that we want to place a bet, but we would wager that many of our clients do not realize they are no longer being accurately monitored for carbon monoxide. If the units you rely on are over 5 years old, throw them out and get new ones! They have probably expired.
Now that spring has arrived and you are cleaning up your landscaping, repairing damage to your home from the winter, putting on your sprinkler system, getting your air conditioning checked an changing filters, you have another item to add to that list.
REPLACE CARBON MONOXIDE DETECTORS and keep my family safe.
