• Make sure the alarm is not receiving excessively noisy power.
Examples of noisy power could be major appliances on the
same circuit, power from a generator or solar power, light dim-

Find the pair of self-adhesive labels included with this Smoke/CO Alarm.
• On each label write in the phone number of your emergency
responder (like 911) and a qualified appliance technician.
• Place one label near the Smoke/CO Alarm, and the other label in
the “fresh air” location you plan to go if the alarm sounds.
NOTE: A qualified appliance technician is defined as “a person, firm,
corporation, or company that either in person or through a representa-

6. Make sure the Smoke/CO Alarm is receiving AC power. Under normal
operation, the green indicator light will shine continuously. If the green
power indicator light does not light, TURN OFF POWER TO THE
JUNCTION BOX and recheck all connections. If all connections are
correct and the green power indicator still does not light when you
restore the power, the unit should be replaced immediately.

3. Plug the power connector into the back of the Smoke/CO Alarm.
4. Position the base of the Smoke/CO Alarm over the mounting bracket
and turn. The Alarm will remain secure over a wide rotation range to
allow for perfect alignment. When wall mounting, this will allow fine-
tuning on the positioning to compensate for out of aligned wall studs
and to keep the wording level. The Alarm can be positioned over the
bracket every 120°. Rotate the Alarm until aligned properly.
