5. Alarm Characteristics
Carbon Monoxide Alarm Indicator
When the alarm senses a dangerous level of CO, the unit will emit a
loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5
seconds of silence. This cycle repeats as long as a dangerous CO
conditions exist.
WARNING:
When powered by battery backup only; after four minutes,
the alarm will sound and flash only once every minute, until the alarm is
reset or the CO is eliminated.
If the battery is low or missing, or if the unit malfunctions, it will display
other readings (and alarm differently) to alert you of specific conditions.
Please familiarize yourself, and other family members, to the difference
between a CO reading and and indication signifying a problem with the
unit itself.
WARNING:
If at any time you test the alarm and it does not perform as
described, have it replaced immediately.
4. Carefully replace the back door. Insure the “latches” on all four
corners of the door are lined up, then press the door securely into
place.
5. Mark the location for the two mounting holes on the wall spaced
vertically 2 5/8" apart.
6. If you are mounting the alarm in plaster board or
drywall, drill a 3/16" hole into the wall and insert
the plastic anchors provided. Install the two screws
provided into the wall or wall anchors until the
screw head is approximately 1/8" from the wall.
7. Hook the unit over the screw head and into the
keyhole in back of the unit.
8. Plug the adapter into an unswitched wall socket.
Table Top Alarm
You can use your Kidde CO alarm as a table top unit. Follow steps 1
thru 4 above. Instead of mounting the unit to a wall, pull out the slide
support and place in a location that is easily visible. Be sure the alarm is
no more than three feet from the floor.
