YOUR CO ALARM IS NOT A SMOKE ALARM!
It is designed to detect carbon monoxide from ANY
source of combustion. It is NOT designed to detect
smoke, fire, or any other gas.
The unit will not work without a properly installed
SensorPack
®
Module. The SensorPack
®
Module will
only warn of carbon monoxide when installed in a
compatible CO Alarm.
How the SensorPack
®
Module Works
The patented SensorPack
®
Module contains two
sensor discs, which mimic the body’s response to CO
over time, and a sealed battery that powers the unit.
When the SensorPack
®
Module is installed in the unit,
light shines through the sensor discs to a receiver.
When no CO is present, light passes through the discs
freely; when the sensor is exposed to CO, the discs
darken. If they darken enough, a “critical” amount of
light is blocked, and the alarm’s horn sounds.
Models NICO, NICOAC, FCD1, and FCD1AC
If the unit alarms, and no one is feeling symptoms of
CO poisoning, you can press the Test/Silence
(Test/Reset) Button on the unit to quiet the alarm signal.
Do not remove the SensorPack
®
Module. (Refer to
“What To Do If Your CO Alarm Sounds”.) The unit will
continue monitoring the air for CO while the sensors
clear. As long as the CO levels remain below 100 ppm
and continue to drop, the unit will remain quiet. If CO
levels rise again or do not drop below 100 ppm, the
unit will go back into alarm. Refer to your CO alarm
User’s Manual for more information on using the
Silence Feature.
Models FACO and FACOAC
If the unit alarms, and no one is feeling symptoms of
CO poisoning, remove the SensorPack
®
Module and
place it where it will be exposed to fresh air, like on the
inside window sill of an open window. Continue to
ventilate your home while the sensors clear.
The sensors should clear in 3-5 hours. Replace the
SensorPack
®
Module in the alarm, making sure you
close the drawer all the way. Test to make sure the CO
alarm and SensorPack
®
Module are working properly.
Removing the SensorPack
®
Module or opening the
drawer will remove your protection. For Models
FACO and FACOAC, always ventilate your home
while the sensors clear.
How To Install a SensorPack
®
Module
1. Cut open the plastic bag and remove the
SensorPack
®
Module.
2. Pull the drawer on the side of the unit open. Insert
the white SensorPack
®
Module in the drawer. The
beveled edge should face in toward unit, label
should face you.
Push the drawer in as far as it will go. Make sure
there is no gap between the unit and the drawer.
The unit may beep a few times after you install the
SensorPack
®
Module.
3. Press the Test/Silence button to make sure the CO
alarm is working properly.
Your Carbon Monoxide Alarm comes with a special
feature that prevents the drawer from closing if a
SensorPack
®
Module is not installed. The CO Alarm
will not work until a SensorPack
®
Module is
installed and the drawer is closed all the way.
