Information About Carbon Monoxide Alarms –
What They Can and Cannot Do
CO alarms provide early warning of the presence of CO, usually
before a healthy adult would experience symptoms. This early
warning is possible, however, only if your CO alarm is located,
installed and maintained as described in this guide.
Because carbon monoxide is a cumulative poison, long-
term exposure to low levels may cause symptoms, as well as
short-term exposure to high levels. This Kidde unit has a time-
weighted alarm – the higher the level of CO present, the sooner
the alarm will be triggered.
This CO alarm can only warn you of the presence of CO. It does
not prevent CO from occurring, nor can it solve an existing
CO problem. If your unit has alarmed and you've provided
ventilation by leaving your windows and doors open, the
CO buildup may have dissipated by the time help responds.
Although your problem may appear to be temporarily solved,
it's crucial that the source of the CO is determined and that the
appropriate repairs are made.
This CO alarm is designed to act as a monitor; it is not designed
for use as a short-term testing device to perform a quick check
for the presence of CO.
CO alarms have limitations. Like any other electronic device, CO
alarms are not foolproof. CO alarms have a limited operational
life. You must test your CO alarm weekly to insure that it is
operating properly at all times.
