GEMC-WL-CO Supervised Wireless Carbon Monoxide Detector Installation Instructions
OVERVIEW
The GEMC-WL-CO is a high-quality UL 2075 carbon
monoxide (CO) detector with built-in supervised digital-
ly-coded radio transmitter. It is compatible with Nap-
co's GEM-RECV and GEMC-RECV Series supervised
receivers that monitor alarms, restores, low battery,
tamper and status. Note: See Control Unit installation
instructions for compatibility.
During normal operation, when unit is in standby mode
and is within proper sensitivity limits, the green LED on
the GEMC-WL-CO flashes once every 10 seconds.
When CO is detected, the GEMC-WL-CO sounds a
local alarm and the transmitter sends an alarm signal
to the supervised receiver. The alarm signal is repeat-
ed as long as CO is still present. A restore report is
sent when the CO detection chamber clears. Supervi-
sion status reports are sent from the GEMC-WL-CO
every minute.
Note: Coding switches are not required or used in
the GEMC-WL-CO; each transmitter is assigned a
unique identification code number at the factory.
The GEMC-WL-CO must be installed in accordance
with the National Fire Protection Association (NFPA)
Standard 720.
INSTALLATION STEPS
1. Remove the Mounting Plate. Remove the
GEMC-WL-CO Mounting Plate by turning the Plate
counter-clockwise and pulling it up.
2. Identify components. Examine the GEMC-WL-
CO to identify the component locations. Take note
of the "Tamper Lock" tab located on the inside of
the Mounting Plate (see image below). Optionally,
cut this "Tamper Lock" tab to prevent the removal
of the GEMC-WL-CO from the Mounting Plate
without using a tool (such as a screwdriver).
3. Install battery. Place one 3-volt lithium Duracell,
Panasonic, Varta or Sanyo type "123A" battery in
its compartment, observing correct polarity. Enroll
the GEMC-WL-CO into the control panel before
mounting. During power up and status initializa-
tion, both the green and red LED's blink four times
every 10 seconds in unison. Then look for the
"standby" indication where the green LED blinks
once every 10 seconds.
Low Battery Warning
The CO detector and transmitter are powered by
one 3-volt lithium battery (supplied) that can power

drops below normal, the red LED will flash every
45 seconds and a low battery report will be sent to
the control panel. If the voltage is still below nor-
mal after 7 days, the detector sounder will chirp.
The battery should be replaced immediately. Op-
eration of the detector cannot be assured after an
additional 7 days of low-battery indication. A low-
battery report is sent to the receiver with any status
transmission.
NOTE: Temperature and humidity extremes
may reduce the life of the battery.
Use Only Battery Specified In Marking. Use of A
Different Battery May Have A Detrimental Effect
On Detector Operation.
4. Pick CO-detector location. The GEMC-WL-CO
must be installed in accordance with the National
Fire Protection Association (NFPA) Standard 720.
Refer to figures in "Recommended Installation Lo-
cations" (on page 3) and all text on pages 3 and
4.
Note: Mounting the GEMC-WL-CO on foil-backed
wallpaper is NOT recommended because the radio
range will be reduced.
5. Install mounting plate. Use two screws and
hardware appropriate for the mounting surface to
secure the mounting plate to the wall or ceiling.
NOTE: Do not install on removable surfaces
such as ceiling tiles.
6. Map the GEMC-WL-CO Transmitter. Referring
to the installation instructions for the control panel
and keypad in use, enter the following:

of the impending test.
A canned CO testing agent may be used to verify the
ability of the GEMC-WL-CO to sense CO by utilizing
the Functional Gas Test Mode. To perform the func-
tional gas test, follow these steps:
a. With a small screwdriver, depress and hold the
recessed "TEST" button for approximately 2 sec-
onds. The detector will temporarily go into alarm
and the red LED will illuminate.
b. Within a few seconds the green LED will start to
blink rapidly indicating the detector is in a speed
up, functional test mode, awaiting gas entry.
c. Spray a very small amount of Solo brand C6
canned CO into one of the 3 small gas entry holes
located on the top center of the detector.
d. Upon successful gas entry and if functioning
properly, the detector will alarm by sounding in a
Temporal-4 pattern with the red LED blinking. An
alarm signal will be sent to the control panel,
providing verification of the alarm signal.
e. The alarm condition at the detector will time out in
20 to 60 seconds or when the CO gas has
cleared.
f. If gas entry is unsuccessful, the test will time out
after 27 seconds.
VISIBLE & AUDIBLE INDICATIONS

CO ALARM PROCEDURE
When a carbon monoxide alarm occurs:
1. Immediately evacuate the premises and move to
fresh air, either outdoors or by an open door or
window.
2. Call emergency services (Fire Department or 911)
3. Ensure that all persons previously within the
premises are accounted for. Do not re-enter the
premises until authorized by emergency ser-
vice responders.
4. If the CO alarm reactivates, repeat steps 1-3 and
call a qualified service technician to investigate all
possible sources of carbon monoxide, such as
from fuel burning appliances and other equip-
ment, and repair all problems found immediately.
Note any equipment not inspected and refer to the
equipment manufacturer's documentation, or con-
tact the manufacturer's directly for more infor-
mation about how the equipment can leak carbon
monoxide into the premises. Ensure all motor
vehicles are not, and have not been, operating in
an attached garage, operating adjacent to the
premises, or operating next to ventilation fresh air
intake vents. Never restart the source of a CO
problem until it has been corrected.
5. If the CO condition that caused the alarm contin-
ues, the alarm will reactivate. Never ignore the
sound of the alarm! If the CO alarm resounds, the
detector is sensing levels of CO that can quickly
become a dangerous situation. EVACUATE IM-
MEDIATELY (repeat steps 1-4).
MAINTENANCE
To keep your detector in functioning correctly, you
must:
 Test the unit once a week by pressing the Test/
Hush button (insert a non-conductive pointed ob-
ject, such as a toothpick)
 Carefully vacuum the unit cover once a month to
remove accumulated dust
 Never use detergents or solvents to clean the unit.
Chemicals can permanently damage or temporarily
contaminate the sensor
 Do not spray air fresheners, hair spray, paint or
other aerosols near the unit
 Do not paint the unit, as paint will seal the vents
and interfere with proper sensor operation
Move the CO detector to a safe and remote location to
prevent damage or contamination prior to performing
any of the following:
 Staining or stripping floors or furniture, painting or
wall-papering
 Using aerosols or adhesives
Note: A Tamper / Trouble signal will be sent to the
control panel when the detector is removed from the
base. IMPORTANT: Reinstall the CO detector as
soon as possible to assure continuous protection.
The following lists possible substances that at some
levels can damage the sensor or cause false alarms:
 Ethylene, ethanol, alcohol, iso-propanol, benzene,
toluene, ethyl acetate, hydrogen, hydrogen sulfide
and sulfur dioxide
 Most aerosol sprays, alcohol based products,
paint, thinners, solvents, adhesives, hair spray,
after shave, perfume, auto exhaust, cleaning
agents, etc.
LOCATIONS TO AVOID
IMPORTANT: Improper mounting locations can
damage the electronic components within the detector.
To avoid damage, to provide optimum performance
and to avoid false alarms, proceed as follows:
 Do NOT install in kitchens, garages, furnace rooms
or in areas that may expose the sensor to sub-
stances that could damage or contaminate it
 Do NOT install in areas where the temperature is
colder than 32°F (0°C) or hotter than 122°F (49°C)
such as crawl spaces, attics, porches and garages
 Do NOT install within 5 feet of heating or cooking
appliances. (we recommend 15 feet to prevent
false alarms)
 Do NOT install near vents, flues, chimneys or any
forced/unforced air ventilation openings
 Do NOT install near ceiling fans, doors, windows
or areas directly exposed to the weather
 Do NOT install in dead air spaces, such as peaks
of vaulted ceilings or gabled roofs, where CO may
not reach the sensor in time to provide early warn-
ing
 Do NOT install this unit near deep-cell large batter-
ies, as these batteries may have emissions that
can cause the detector to perform at less than opti-
mum performance
 Do NOT obstruct the vents located on the unit
 Do not mount the unit where drapes, furniture or
other objects can block the flow of air to the detec-
tor

GEMC-WL-CO Supervised Wireless Carbon Monoxide Detector Installation Instructions
GENERAL WARNINGS
 Read these installation instructions in their entirety
before installing the GEMC-WL-CO detector.
Leave these instructions with the owner/user of the
detector.
 The GEMC-WL-CO is intended for use in indoor
locations only
 Failure to properly install, test and/or maintain the
GEMC-WL-CO may cause it to fail, potentially re-
sulting in loss of life
 Installation of this detector is not a substitute for
proper installation, use, and maintenance of fossil
fuel-burning appliances, including appropriate ven-
tilation and exhaust systems
 To reduce the risk of carbon monoxide poisoning,
test detector operation weekly
 Do not paint the detector
Carbon monoxide detectors are NOT smoke detectors.
A carbon monoxide detector is NOT a substitute for
smoke detectors. This carbon monoxide detector is
specifically designed to detect the presence of carbon
monoxide gas and is NOT designed nor intended to
detect smoke, fire or any other gas. In addition, this
detector will only indicate the presence of carbon mon-
oxide at the sensor; carbon monoxide gas may be pre-
sent within other areas of the premises.
CARBON MONOXIDE POISONING
The following are some of the possible carbon monox-
ide poisoning symptoms that should be presented to
and discussed with all occupants of the protected
premises:
 Mild exposure: "Flu-like" symptoms, including
but not limited to slight headache, nausea, vomit-
ing, fatigue, runny nose and sore eyes
 Medium exposure: Severe throbbing head-
ache, dizziness, drowsiness, confusion, fast heart
rate
 Extreme exposure: Loss of consciousness,
brain damage, convulsions, cardio-respiratory fail-
ure, death
Often cases of reported CO poisoning indicate that
while victims are aware they are unwell, they become
so disorientated that they are unable to save them-
selves by either exiting the building or calling for assis-
tance. Young children and pets may be the first affect-
ed.
SOURCES OF CARBON MONOXIDE
Potential carbon monoxide sources include fuel-fired
appliances (space heaters, furnaces, water heaters,
ranges, ovens, clothes dryers); other sources
(kerosene-burning stove or heater, or gas log fire-
place); or internal combustion engines. In addition,
excessive exhaust spillage or reverse venting of fuel-
burning appliances can produce dangerous transient
levels of CO. This can be caused by external condi-
tions, such as:
 Wind direction, velocity, or a combination of both,
including high gusts of wind or insufficient draft in
vent pipes
 Temperature inversions that can trap exhaust gas-
es near the ground
 Negative pressure differential resulting from the
use of exhaust fans
 Simultaneous operation of several fuel-burning ap-
pliances competing for limited internal air
 Vent pipe connections vibrating loose from dryers,
furnaces, or water heaters
 Obstructions in vent pipes or unconventional vent
pipe designs that can amplify the above situations
 Poorly designed or maintained chimneys and/or
vents
 Extended operation of unvented fossil fuel-burning
devices (range, oven, fireplace, etc.)
 Idling cars in an open or closed attached garage,
or near the premises
GENERAL LIMITATIONS
OF CARBON MONOXIDE DETECTORS
This detector is designed to protect individuals from
the severe effects of CO exposure. It will not fully
safeguard individuals with specific medical conditions.
If in doubt, consult a medical practitioner.
If the unit is in trouble or has arrived at the end of its
life, it may not sense CO and cannot be relied upon to
monitor CO levels. Replace the CO detector by the
date specified on the unit or when the detector indi-
cates an end of life condition, whichever comes first.
CO detectors are not a substitute for designated life
safety devices. Napco does not warrant or imply in
any way that a CO detector will protect lives from CO
poisoning. These detectors should only be considered
as an integral part of a comprehensive safety program.
