CHECKOUT & TROUBLESHOOTING
1. Supply house power to the CO alarm, green indicator will be on.
The red indicator light should flash approximately every 15-30
seconds, showing that the CO alarm is operating properly.
2. If red light is not flashing or the green LED is not on:
a. Check that AC power is working.
b. Check that the battery is installed.
c. Push test button. Alarm will go into self test mode.
d. Check the connector plug and wire connections. NOTE: Be
sure you turn off power before checking wire connections.
e. If the power supply and wiring check out, but the red light does
not flash or the green LED is still off, return the unit to the
manufacturer. See TO RETURN A COALARM section.
3. When powering up devices in a tandem installation and all
the alarms sound immediately, inspect all devices for a solid
green LED. Verify wiring of units, if wiring checks and problem
remains the devices with flashing red LED are the trouble units
and should be replaced.
IF YOUR CO ALARM SOUNDS
Actuation of the CO alarm (temporal 4 tone) indicates the
presence of carbon monoxide (CO) which can kill you. If the
CO alarm sounds, do not ignore the unit!
Enclosed with the unit are two (2) labels to add the telephone
numbers of the emergency service provider and a qualified
technician. Once CO alarm is installed, place one (1) label next
to the CO alarm and place the other label near the fresh air
source at your prearranged meeting place after leaving the
house.
IF THE ALARM SIGNAL SOUNDS:
1. Operate the Test/Reset button. While the alarm has been reset,
the device will continue to monitor the air for the presence of CO.
If the alarm sounds again after 5 minutes there are CO levels that
are potentially dangerous.
2. Call emergency services, fire department or 911. Write the
number of your local emergency service here:
Do not tandem using both the red/yellow wire and brown/yellow
wire. Only 1 tandem interconnect wire is needed between units.
CAUTION: Failure to observe any of the conditions set forth may
cause system malfunction and damage to the alarm.

house. Verify all persons are accounted for. Do not re-enter
premises or move away from the fresh air until the emergency
responder has arrived, the premise has been aired out and the
CO alarm remains in normal condition.
4 After following steps 1-3, if the CO alarm reactivates within a 24-
hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances as well as inspect for proper operation
of this equipment. If problems are identified during this inspection
have the equipment serviced immediately. Note any combustion
equipment not inspected by the technician and consult the
manufacturers’ instructions, or contact the manufacturers directly
for more information about CO safety and this equipment. Make
sure that motor vehicles are not and have not been operating in an
attached garage or adjacent to the residence. Write down the
number of a qualified appliance technician here:
