U.S.A., 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.
Do not cover or obstruct visual alarm LED. Doing so may adversely affect product performance and result in sickness
or death.
Do not disassemble unit or attempt to repair or modify any component of this detector. This detector contains no user
serviceable parts, and substitution of components may adversely affect product performance and result in sickness
or death.
This detector helps monitor for the presence and concentration level of carbon monoxide gas. Misuse may produce
an inaccurate reading, which means that higher levels of the gas being monitored may be present and could result in
overexposure and cause sickness or death. For proper use, see supervisor, User Instructions, or call 3M in U.S.A.,
1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.
When the unit is turned on it performs a self-test, which activates the visual alarms. If the self-test fails, or the alarm does
not activate, do not use. Failure to do so may adversely affect product performance and result in sickness or death.
Immediately exit the environment if it causes an alarm condition on the detector. Failure to do so may result in sickness
or death.
CM-16A may not function effectively below 40°F (4.4°C) or above 100°F (37.8°C). Using the detector outside of this
temperature range may adversely affect product performance and result in sickness or death.
This product is intended for use in ordinary indoor locations of family living units and office workspaces. The CM-16A is
not designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial
standards.
To help avoid false alarms, the CM-16A is not intended for low level detection (below 30 ppm) of carbon monoxide per
UL 2034.
Individuals with certain medical problems may consider using warning devices that provide audible and visual signals for
carbon monoxide concentrations below 30 ppm.
The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the
household:
Mild exposure: Slight headache, nausea, vomiting, fatigue (often described as “Flu-like” symptoms).
Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Unconsciousness, convulsions, cardio respiratory failure, and death.
Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become
so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Young children and
household pets may be the first affected.
Transient CO situations can occur:
1. Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as:
a) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with
extended periods between cycles).
b) Negative pressure differential resulting from the use of exhaust fans.
c) Simultaneous operation of several fuel-burning appliances competing for limited internal air.
d) Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.
e) Obstruction or unconventional vent pipe designs, which can amplify the above situations.
2. Extended operation of un-vented fuel burning devices (range, oven, fireplace, etc.).
3. Temperature inversions, which can trap, exhaust gases near the ground.
4. Car idling in an open or closed attached garage, or near a home.
CAUTION: This detector will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may
be present in other areas. Accommodation spaces should be well ventilated when household cleaning supplies or similar
contaminants are used.

This product is intended for use in ordinary indoor locations of family living units and office workspaces. The CM-16A is not
designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or
industrial standards.
Do NOT mount the unit in the garage. Do NOT mount the CM-16A where the normal ambient temperature is below 40°F (4.4°C)
or exceeds 100°F (37.8°C), or within 5 feet (1.5 meters) of a cooking or heating appliance.
6. The alarm relay of the CM-16A is a dry contact and rated at 1 Amp, 125V at 30 VA. It is not suitable for fan control use.
When connecting the units to remote buzzers or other devices, make sure that the load does not exceed the relay’s rating.
External buzzers must be capable of generating a sound output greater than 85 dBA at 10 ft.
INSTALLATION
1. In the configuration as normally shipped, the CM-16A has a three-part case. This allows the unit to mount flush to a wall
over a single gang electrical box (not included). If the back cover is removed, (remove the two screws inside), the CM-16A’s
mount on a two gang, old work box or a 4 X 4 electrical box, provided by the installer.
2. The detector may be installed on either a ceiling or a wall. If installed on a peaked, gabled, or sloped ceiling, it should be
located about 3 feet from the highest point. The unit can be placed vertically or horizontally on a wall, so the information on
the front of the CM-16A can be read in a normal manner. Do NOT mount the CM-16A in a corner. Use the same spacing as
for smoke detectors-- 30 foot (9 meters) centers, 900 sq. feet (83 sq. meters) per detector.
3. The CM-16A‘s have terminal strips to connect to the cables from the control panel or other device. When connecting the
unit, follow good wiring practices, and ensure the power is turned off. Access to the terminal strip will be easier if the back
cover is off.
4. Ensure that the CM-16A is connected to a continuous source of power (not controlled by a wall switch). The CM-16A power
consumption figures represent worst-case conditions under AC power; DC performance may vary.
5. See wiring diagram for information on connections of the CM-16A. 3M™ Macurco™ recommends a minimum of 22 AWG
wire for runs up to 200 ft., and 18 AWG wire for longer runs.

Power Up
When the unit is turned on it performs a self-test, which activates the visual alarm. If the self-test fails, or the alarm does
not activate, do not use. Failure to do so may adversely affect product performance and result in sickness or death.
When the detector is first powered, the status light will alternate between RED and GREEN as the unit performs a 2-1/2 minute
warm-up cycle and self-test procedure. The buzzer on the CM-16A will cycle twice, emitting its characteristic 4-chirp tone. At
the end of this 2-1/2 minute cycle, the status light will turn GREEN to indicate normal operation and safe air. The alarm relay is
not energized during the 2-1/2 minute warm-up cycle.
Operation
The CM-16A continuously monitors the air. If the CM-16A measures levels of CO greater than the danger level, the RED light
will turn on, the Alarm Relay will switch to actuate the alarm circuits in the control panel, and the buzzer on CM-16A units will
sound. The computer in the CM-16A is programmed to alarm if the danger levels of carbon monoxide are exceeded, which are
time and concentration related. When the detector is first powered, the status light will alternate between RED and GREEN as
the unit performs a 2-1/2 minute warm-up cycle and self-test procedure. At the end of this 2-1/2 minute cycle, the status light
will turn GREEN to indicate normal operation and safe air. The alarm relay is not energized during the 2-1/2 minute
warm-up cycle.
Individuals with certain medical problems may consider using warning devices that provide audible and visual signals for
carbon monoxide concentrations below 30 ppm.
ALARMS
The alarm points are: 70 ppm of CO after 60 to 240 minutes, 150 ppm of CO after 10 to 50 minutes, and 400 ppm of CO
after 4 to 15 minutes, in accordance with the provisions of UL Standard 2034. This product is not UL listed. The CM-16A will
automatically come out of alarm once the air clears. The time to stop alarming will depend on the CO exposure time and the
CO level.
Immediately exit the environment if it causes an alarm condition on the detector. Failure to do so may result in sickness
or death.
The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL
members of the household:
- Mild exposure: Slight headache, nausea, vomiting, fatigue (often described as “Flu-like” symptoms).
- Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate.
- Extreme Exposure: Unconsciousness, convulsions, cardio respiratory failure, and death.
Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they
become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Young
children and household pets may be the first affected.
Transient CO situations can occur:
1. Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as:
a) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with
extended periods between cycles).
b) Negative pressure differential resulting from the use of exhaust fans.
c) Simultaneous operation of several fuel-burning appliances competing for limited internal air.
d) Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.
e) Obstruction or unconventional vent pipe designs, which can amplify the above situations.
2. Extended operation of un-vented fuel burning devices (range, oven, fireplace, etc.).
3. Temperature inversions, which can trap, exhaust gases near the ground.
4. Car idling in an open or closed attached garage, or near a home.
RESET/SILENCE SWITCH
The switch on the front of the CM-16A labeled “TEST/RESET,” performs three functions.
1. A short press of switch, less than 5 seconds, will place the unit into self test mode with no alarm relay activation. The
status light will turn red for 5 seconds and then it will alternate slowly between green and amber while the self-test
executes. The controlling software simulates a 3000 ppm CO environment and causes the unit to alarm after approximately
one minute has elapsed. When this happens, the status light turns red for five seconds. The unit will then return to normal
operation.
2. A long press of switch, 5 or more seconds long, will place the unit into self-test mode with alarm relay activation. Pressing
and holding the switch will cause the status light to turn red for 5 seconds and then switch to solid amber. The alarm relay
will then be activated and the switch can be released. After about 5 seconds, the alarm relay will turn off and the status
light will alternate slowly between green and amber while the self test executes. The controlling software simulates a 3000
ppm CO environment and causes the unit to alarm after approximately one minute has elapsed. When this happens, the
status light turns red for five seconds. The unit will then return to normal operation.
3. If the CM-16A is in an alarm condition due to the detection of carbon monoxide, one push of the switch will cause the
alarm relay to open for five minutes. After the five-minute period, if CO is still present, the status light will again switch to
RED, the alarm relay will close. If after the five-minute period, the detected CO level has dropped below 70 ppm, the
CM-16A unit will reset.

Do not cover or obstruct visual alarm LED. Doing so may adversely affect product performance and result in sickness or
death.
TROUBLE INDICATOR
Internal failure of the CM-16A will cause an open circuit in the normally closed (NC) Trouble Relay to provide for actuation of
the control panel circuits. The status LED will flash AMBER. See ERRORS section. The CM-16A microprocessor continuously
monitors various detector parameters. Failure of the CM-16A’s internal power supply or a lack of power to the detector will
result in the status light remaining OFF (not illuminated). In this case, the most common cause of detector trouble would be a
break in the wiring between the control panel and the CM-16A.
ERRORS
The CM-16A continuously monitors various internal operating parameters. If a problem is found, the unit will switch to Trouble
mode. See TROUBLE INDICATOR section. To reset the unit for normal operation, press the TEST/RESET switch, or remove
power to the unit, wait a few seconds, then re-apply unit power. If this problem persists, your detector requires repair; contact
the alarm panel installer or 3M™ Macurco™ Tech Support for advice. If repair is required, return the unit to manufacturer to
comply with warranty.
MAINTENANCE
Do not disassemble unit or attempt to repair or modify any component of this detector. This detector contains no user
serviceable parts, and substitution of components may adversely affect product performance and result in sickness
or death.
The CM-16A has a long life solid state sensor. The CM-16A will go into a Trouble Fault when the sensor has expired. All
maintenance and repair of products manufactured by 3M™ Macurco™ are to be performed at the 3M Macurco Service Center.
3M™ Macurco™ does not sanction any third-party repair facilities.
TESTING
The CM-16A should be tested monthly by pushing the TEST/RESET switch; see TEST/RESET switch. Normally this will be the
only test required for the CM-16A and is the recommended way to test the unit or units after installation. All CM-16A units are
factory calibrated and 100% tested for proper operation. The unit also has the ability to automatically self test and does so
every 2 1/2 minute cycle. If the unit detects an improper voltage or inoperable component it will default into Trouble mode. See
TROUBLE INDICATOR section. Check that the CM-16A status indicator light is illuminated (GREEN) continuously. If not, do not
proceed with the tests. Though there is no field calibration procedure for this unit, there is an optional field test procedure.
CLEANING
The CM-16A should be cleaned using the soft brush attachment of your vacuum cleaner. The CM-16A should be tested after
cleaning to ensure the unit is operating normally.
SENSOR POISONS
The gas sensor in the detector is designed with extreme sensitivity to the environment. As a result, the CO sensor may be
damaged if it is exposed to a direct spray from aerosols such as paints, silicone vapors, etc., or to a high density of corrosive
gases such as hydrogen sulfide or sulfur dioxide for an extended period of time. The sensor may react to chemicals such as
ammoniated cleaning agents, volatile solvents and hydrogen gas. In sufficient concentration, these chemicals may cause a
false alarm.
CAUTION: This detector will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may
be present in other areas. Accommodation spaces should be well ventilated when household cleaning supplies or similar
contaminants are used.
