4. INFORMATION ABOUT CARBON MONOXIDE

WHAT IS CARBON MONOXIDE? Carbon monoxide (CO) is a highly toxic, invisible, odorless, tasteless gas.

HOW IS CO GENERATED? Carbon monoxide is generated through incomplete combustion of fuel in various appliances. Faulty ventilation of furnaces, boilers, water heaters, fireplaces, wood burning stoves, and space heaters are the major cause of CO levels in a building. Automobile, forklift and small engine exhaust are another source of CO.

HOW DOES CO POISON PEOPLE? The human body depends on oxygen for the burning of fuel (food) to provide us with the energy that allows our cells to live and function. Oxygen makes up approximately 21% of the atmosphere and enters our lungs when we breathe. In our lungs the oxygen combines with the hemoglobin in the blood (oxyhemoglobin), and is carried in the blood stream throughout the body where it releases oxygen to the cells. Carbon monoxide is dangerous because it bonds more tightly to the hemoglobin (carboxyhemoglobin, COHb) than oxygen does. When CO combines with hemoglobin, the hemoglobin’s ability to combine with oxygen is lost. As the COHb concentration rises, people become nauseous, unconscious and ultimately die (see below).

WHAT ARE THE SYMPTOMS OF CARBON MONOXIDE POISONING? Many people often confuse carbon monoxide poisoning with the flu; the initial symptoms being very similar. Different concentrations of CO over various lengths of time cause different symptoms. The following symptoms may be related to CARBON MONOXIDE POISONING and should be discussed with EVERYONE.

MILD EXPOSURE: MEDIUM EXPOSURE: EXTREME EXPOSURE:

Slight headaches, nausea, vomiting, running nose, sore eyes, fatigue (often described as “Flu-like” symptoms).
Severe throbbing headache, dizziness, drowsiness, confusion, fast heart rate.
Unconsciousness, convulsions, cardiorespiratory failure, brain damage, death.

Many cases of CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become so disoriented that they are unable to save themselves by either exiting the building or calling for assistance. Older adults, young children, pregnant women (and their unborn children), and persons with medical conditions are typically the first affected.

5. RECOMMENDED LOCATION OF DETECTORS
CO poisoning can happen anywhere in the building. A CO detector should be installed on every floor, and inside or near every area or room that may be occupied. Carbon monoxide at room temperature (68oF) is slightly lighter than air (density of CO 0.96716 compared to air). CO detectors should be mounted five feet off floor, around eye level, for best operation and to easily test detector and view any display. Install a CO detector: 1. On every floor, at least one CO detector for every 1000 square feet of vertically
unobstructed space. 2. Inside any room that is occupied by someone who may be hypersensitive to CO,
such as older adults, young children, pregnant women, or persons with medical conditions. 3. Near each exit from the building and any maintenance room that contains combustion equipment, such that an alarm signal will be heard before anyone enters the building or maintenance room. For residential areas within a commercial building, carbon monoxide alarms that are listed to the UL 2034 residential standard, like the Defender CA6150, should be installed inside or near every sleeping area or room, according to the manufacturer’s instructions.

6. LOCATIONS TO AVOID

NEAR A COOKING AREA:

Do not install the detector within five feet of any

cooking appliances. CO may be generated in the cooking process and cause nuisance

alarms. Also, cooking grease can build up on the detector and cause detector failure.

Any detector that is installed near a commercial cooking area should be cleaned at least

once every month, or more frequently if needed.

WITHIN FIVE FEET OF A FURNACE, BOILER, WATER HEATER, OR SPACE HEATER: These devices often spill out small amounts of CO when they first turn on.

IN GARAGES: Automobile exhaust contains CO and will activate alarm.

IN DUSTY AREAS: Dust can build up on detector and prevent it from working properly.

IN CLEANING SUPPLY ROOMS: Cleaning chemicals and painting supplies may cause nuisance alarms.

IN UTILITY OR BATH ROOMS: Do not install the detector inside or within three feet of a room with a bathtub, shower, spa or washer/dryer. Excessive moisture may cause nuisance alarms.

IN VERY HOT OR COLD AREAS: Do not install unit onto any exterior wall or in areas which are below 40oF or above 100oF.

IN DEAD AIR SPACE: Do not install detector within one foot of where wall meets ceiling or floor.

IN HAZARDOUS LOCATIONS: This detector is not suitable for installation in a hazardous location, as defined in the National Electrical Code.

NEAR WIRELESS DEVICES: Do not install the detector within one foot of wireless devices. Radio Frequencies (RF) may interfere with the CO detector’s proper operation.

8. FUNCTIONS AND OPERATION

OPERATION: The CO detector is operational once the activation switch is slid to ON position, and a one minute warm-up is complete. The POWER green LED will flash
once every 60 seconds, and model CD8180 LCD continuously display .

LOW BATTERY CONDITION: When the battery voltage drops below an acceptable level, the detector will chirp once per minute and the POWER green LED will blink 5

seconds every minute. The model CD8180 LCD will also display

symbol. The

detector will continue to sample for carbon monoxide, and model CD8180 automatically

display CO levels detected of 30 ppm or more, until battery power drops below

minimum voltage requirement. See Section 13 for information regarding service.

SERVICE CONDITION: An internal microcontroller continuously monitors the sensor function and other critical components. If an internal failure of any of these components should occur, the detector will chirp twice (BEEP – BEEP) per minute, SERVICE red LED will blink for 5 seconds every minute, and model CD8180 LCD will continuously display
. This malfunction condition indicates a problem with the unit. See Section 13 for information regarding service.

SENSOR END-OF-LIFE CONDITION: The electrochemical sensor has a minimum five year life expectancy. Once the batteries are activated, a microcontroller monitors the total time that the detector is under power. After five years of service, the sensor “End-of-Life” signal will be activated; the detector will chirp once per minute, and the SERVICE red LED will glow for 3 seconds at the same time. The model CD8180 LCD

will also continuously display

to indicate that the sensor life has expired and the

detector must be replaced. See Section 13 for handling an End-of-Life alarm.

ALARM CONDITION: When the batteries are active, and CO gas is detected at a level and duration specified in Section 3 CO RESPONSE TIMES, the horn will sound and the ALARM red LED will light. The initial 5 minutes of an alarm signal will repeat 4 short beeps, 5 second pause, 4 short beeps, etc. Afterwards, the alarm signal will change to 4 short beeps with 60 second pause. The ALARM red LED will flash in sync with the beeping sound. The model CD8180 LCD will also display the current CO level detected. The alarm signal is either manually or automatically reset. See Section 10 WHAT TO DO WHEN THE ALARM SOUNDS.

TEST/RESET/MUTE BUTTON: The TEST/RESET/MUTE button is used to check the detector for proper operation, and to temporarily mute horn for 5 minutes when alarm is

activated, for 24 hrs. during the first week of a “Low Battery Voltage” signal ( )

activation, or for 60 hrs. during the first month of an “End-of-Life” signal ( ) activation. The model CD8180 LCD will display the current CO level detected when detector is

being tested, or

when an alarm signal is muted. See Section 9 for detailed

instructions to test the detector and mute the audible horn.

LCD DISPLAY FUNCTION (FOR MODEL CD8180): When detector is operating
normally, the LCD will continuously display . If a CO level of 30 ppm or more is detected, or alarm is activated, the LCD will automatically display the current CO level detected. The LCD will display the symbol if the batteries have low voltage.

9. TEST AND MUTE DETECTOR

Test the detector weekly by pressing the TEST/RESET/MUTE button on the cover and holding it down for a minimum of 2 seconds, or until the detector starts beeping and ALARM red LED flashes, then releasing. This test will simulate a CO concentration of approximately 300 ppm CO gas. The detector will sound 4 short beeps and ALARM red LED will flash at the same time, followed by a 5 second pause, and then repeat 4 more short beeps with flashing ALARM red LED if all of the electronic circuitry and buzzer are working correctly. The current CO level will also be displayed for model CD8180. To reduce the horn volume, place the palm of one hand over the horn opening.

In addition to the weekly simulation test, Defender Commercial CO Detectors should be tested with a UL Classified CO Detector Test Kit (CaT KIT1 or equivalent) at least once per year.

Place the Tester’s enclosure over the detector, and follow the Tester’s instructions to perform the CO gas test correctly. The detector should activate the visual and audible alarm signals within 5 to 10 minutes, and model CD8180 display about 600 ppm, if the proper amount of CO gas is injected for about 5 to 6 seconds.

If too much CO gas is injected, the detector will trigger the trouble signal (2 short beeps, SERVICE red LED

blinks for 5 seconds, and CD8180 LCD displays ). Remove the enclosure from the CO detector and purge the CO with fresh air for a few minutes until the detector returns to normal (POWER

green LED flashes once every minute, and CD8180 LCD displays test with a lesser amount of CO spray.

), then repeat the

When the detector’s alarm signals are activated (ALARM red LED flashes in sync with 4 short beeps every 6 seconds), remove the enclosure from the CO detector, and press the TEST/RESET/MUTE button to silence the horn. When the CD8180 LCD displays
, press the DISPLAY CO LEVEL button, and, while the test data is being displayed, press the TEST/RESET/MUTE button to erase the record. The detector is now verified to be responsive to CO gas.

To mute the audible horn during an alarm signal, press the TEST/RESET/MUTE button.

The ALARM red LED will flash 4 times, the model CD8180 will display

for 5

seconds, and the horn will be temporarily silenced. If a CO level of 50 ppm or more

continues to be detected, the audible and visual alarm signals will be automatically

reactivated within 5 minutes. See Section 10 WHAT TO DO WHEN THE ALARM

SOUNDS.

10. WHAT TO DO WHEN THE ALARM SOUNDS
If alarm signal sounds:

1. Operate test/reset/mute button; 2) Call your emergency services (tel. no. ___)
   [fire department or 911]; 3) Immediately move to fresh air – outdoors or by an open door or window. Do
   a head count to check that all persons are accounted for. Do not re-enter the premises or move away from the open door/window until the emergency services responders have arrived, the premises have been aired out, and your detector remains in its normal condition. 4) After following steps 1- 3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and call a qualified appliance technician
   (tel. no. ____) to investigate for sources of CO from fuel burning equipment and appliances, and 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 or forklifts are not, and have not been, operating in an attached garage or adjacent to building.
   MANUAL RESET: You can temporarily silence an audible alarm signal by pressing the TEST/RESET/MUTE button. The ALARM red LED will flash 4 times, and the model CD8180 will display for 5 seconds and then continue to display the current CO level detected from 30 to 999 ppm. If 50 ppm or more continues to be detected, the audible and visual alarm signals will be automatically reactivated within 5 minutes. Do not wait to see if the alarm is reactivated; follow above instructions immediately.
   AUTOMATIC RESET: If a CO alarm activation is not manually reset, the horn will sound for at least 15 minutes. After 15 minutes, the detector will automatically reset itself and return to normal operation if the CO level detected drops below 10 ppm.
   If the building has been temporarily vacant and you return to find the detector(s) sounding, do not enter the building. Call the Fire Department from another location. Do not re-enter the building for any reason until you have been assured that it is safe to do so.
   Conditions which can result in transient CO situations: 1) Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as: i) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). ii) Negative pressure differential resulting from the use of exhaust fans.
   – 16 –

iii) Simultaneous operation of several fuel burning appliances competing for limited internal air.
iv) Vent pipe connections vibrating loose from clothes dryers, furnaces, boilers, or water heaters.
v) Obstructions in or unconventional vent pipe designs which can amplify the above situations.
vi) Poorly designed or maintained chimneys and/or vents. 2) Extended operation of unvented fuel burning devices 3) Temperature inversions which can trap exhaust gases near the ground. 4) Car or forklift idling in an open or closed attached garage, or near building. If service signal (chirps twice and SERVICE red LED blinks 5 seconds in every minute) or low battery signal (chirps once and POWER green LED blinks 5 seconds in every minute) are activated, see Section 13 for service and return instructions.
– 17 –

11. LIMITATIONS OF CO DETECTORS
Carbon monoxide detectors respond to the presence of CO. They do not detect smoke. If the alarm does activate, follow instructions in Section 10 WHAT TO DO WHEN THE ALARM SOUNDS.
Carbon monoxide detectors are devices that can provide an early warning of the presence of CO gas at a reasonable cost. However, detectors have sensing limitations and may not always sound a warning in the presence of CO. The detector will not operate if the battery power is low or dead. CO detectors must be tested regularly to ensure that they are receiving power and operating properly. Carbon monoxide detectors cannot sense CO that does not reach the detector, and therefore CO detectors may not detect CO which is in another area of the building. Furthermore, the detector may not alert someone who is located on a different level of the building or on the other side of a closed door. The use of drugs and alcohol may impair one’s ability to hear the detector. If it is a multi-level building, install CO detectors on each level. If the detector is installed in a hallway and office or room doors are kept closed while occupied, install a CO detector within each office and room.
Although CO detectors can help save lives by providing an early warning to the presence of carbon monoxide, they are not a substitute for an insurance policy. Employers, property owners, leaseholders, and renters should have adequate insurance to protect everyone’s health, lives and property.
12. GOOD SAFETY HABITS
DEVELOP AND PRACTICE A PLAN OF ESCAPE: Make a floor plan indicating all doors and windows and at least two escape routes from each room within the building. Have a meeting with everyone to discuss your escape plan, and show everyone what to do in case a detector sounds an alarm signal. Determine a place outside the building where you can all meet if a detector sounds. Familiarize everyone with the sound of an alarm signal, and train them to leave the building when they hear it. Practice a CO fire drill at least once every six months. Practice allows you to test your plan before an emergency. You may not be able to reach everyone. It is important that they all know what to do. Discuss the symptoms related to CARBON MONOXIDE POISONING with everyone. (See Section 4 WHAT ARE THE SYMPTOMS OF CARBON MONOXIDE POISONING?)
– 18 –

13. DETECTOR END-OF-LIFE AND SERVICE
After the detector has been activated for five years, the detector reaches the end of its life and emits the End-of-Life signal. The detector will chirp once per minute, SERVICE red LED will glow for 3 seconds at same time, and model CD8180 will continuously display . The detector must be replaced once the End- of-Life signal has been activated. See below procedures to remove and deactivate the detector, and discharge the batteries. The detector can be disposed of using the same method for disposing of discharged lithium batteries. Should the low battery voltage signal occur in less than five years after initial activation, the battery power capacity may be low because of long-term storage prior to installation, exposure to low or high temperatures or high humidity during storage or operation, or abnormal usage. If the low battery voltage signal is activated in less than five years under normal conditions, press the TEST/RESET/MUTE button to mute the audible low battery voltage signal, and place the CO detector in an environment at 68oF or warmer. If the low battery voltage signal resumes within 24 hours, follow the steps below to deactivate the detector, and the instructions listed on the last page of this Owner’s Manual to return the unit for warranty service. In the event of any malfunction of the unit, the detector will chirp twice per minute, the SERVICE red LED will blink for 5 seconds every minute, and the model CD8180 will continuously display . Do not attempt to repair the detector. This product should be serviced by a qualified service technician. Follow the steps below to deactivate the detector, and the instructions listed on the last page of this Owner’s Manual to return the unit for warranty service.

Further, the warranty does not cover acts of God, such as fire, flood, earthquakes, hurricanes and tornadoes. The manufacturer shall not be liable for any incidental or consequential damages caused by the breach of any express or implied warranty. Except to the extent prohibited by applicable law, any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the duration of the above warranty. Some states or jurisdictions do not allow the exclusion or limitation of incidental or consequential damages or limitations on how long an implied warranty lasts, so the above limitations or exclusion may not apply to you.
