What CO Alarms 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 only possible if your CO alarm is
mounted, installed, and maintained as
described in this user manual.
Because CO is a cumulative poison, symptoms
can be caused by long-term exposures to low
levels or short-term exposures to high levels.
Your SMCCO10-Z has a time-weighted alarm;
the higher the level of CO present, the sooner
the alarm is triggered.
Your SMCCO10-Z can only warn you about the
presence of CO. It does not prevent CO from
occurring and cannot solve existing CO
problems. If your SMCCO10-Z has alarmed and
you 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 is crucial that the source
of the CO be determined and appropriate
repairs made.
CO alarm have limitation. Like any other
electronic device, CO alarms are not fool-
proof. CO alarms have a limited operational
life. You must test your CO alarm weekly,
because it could fail to operate at any time.
If your CO alarm fails to test properly, or if its
self-diagnostic test reveals a malfunction,
replace the unit immediately. Your SMCCO10-Z
will not monitor CO levels while in an trouble
condition.
CO alarm can only sense CO that reaches the
unit’s sensor. It is possible that CO may be
present in other areas without reaching the
alarm. The rate and ability with which CO
reaches the alarm may be affected by:
Doors or other obstructions.
Fresh air from a vent, an open window,
or other source.
CO being present on one level of the
home and not reaching a CO alarm
installed on a different level. (For
example, CO in the basement may not
reach an alarm on the second level, near
the bedrooms).
