Limitations Of Carbon Monoxide Alarms - Pro-Tech 7030SL Owner's Manual

AUTOMATIC RESET: If a CO alarm activation is not manually reset, the horn will
sound for at least 5 minutes. After 5 minutes, the alarm will automatically reset itself
and return to normal operation if the CO which caused the alarm activation has cleared.
IF YOU HAVE BEEN AWAY FROM HOME and you return to find your alarm(s)
sounding, DO NOT ENTER YOUR HOME. Call the Fire Department from a
neighbor's home.
YOU HAVE BEEN ASSURED THAT IT IS SAFE TO DO SO.
Conditions which can result in transient CO situations:
1) Excessive spillage or reverse venting of fuel burning appliances caused by
outdoor ambient conditions, such as:
i) Wind direction and/or velocity, including high gusts of wind. Heavy air in
the vent pipes (cold/humid air with extended periods between cycles).
ii) Negative pressure differential resulting from the use of exhaust fans.
iii) Simultaneous operation of several fuel burning appliances competing for
limited internal air.
iv) Vent pipe connections vibrating loose from clothes dryers, furnaces, or
water heaters.
v) Obstructions in or unconventional vent pipe designs which can amplify
the above situations.
vi) Poorly designed or maintained chimneys and/or vents.
2) Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.).
3) Temperature inversions which can trap exhaust gases near the ground.
4) Car idling in an open or closed attached garage, or near a home.
If "service" (trouble) signal activates (chirps twice every minute, red LED blinks
for 5 seconds at same time), see Section 12 for service and return instructions.
