FOR MODEL
CO910 OWY:
fatures a Digital LED Display (Light Emitting
will show the level of carbon monoxide present
are concentrations of 50 parts per million
(ppm) or greater. See pages 8 and 9 for more information
This model

Reading the Digital LED Display
.-When-there is no--carbon monoxide
(CO)
present or-very
low levels, your LED Display will show three lines “- - -‘.
These lines are the normal readout and indicate your
environment does not have a CO problem. If CO is
detected in higher concentrations. your LED Display will
show the ppms present in increments of 10 starting at 50
(i.e. 50, 60. 70 etc.). Beyond 150 ppm. the unit
will
show
“H I”,
which indicates high or dangerous levels of
CO. It is normal for the LED display to blink for up to
5 minutes when first plu
gged in. The LED will show
“ERR”
if malfunctioning (see page 16.).
Responding to your Digital LED Display
Your unit is constantly monitoring the air and will
activate a low level warning if low levels of CO are
present. Also, your unit will go into full alarm if
ongoing, dangerous levels of CO are detected. See
Page 24 for the specific times and levels required.
Follow the instructions on pages 20 and 21 or pages
22 and 23 if either the full alarm sounds or the low
level warning activates.
