WARNING! ® The Pro-Tech 8505 Commercial CO Monitor is not designed for use in vehicles or unconditioned spaces, and is not listed to the residential UL 2034 standard. This monitor is intended for use within commercial buildings that are heated and air conditioned between 40°...
3. 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 a byproduct of the incomplete combustion of fuel. Faulty ventilation of furnaces, space heaters, boilers, water heaters and kitchen appliances are a major cause of high CO levels in a building.

5. RECOMMENDED LOCATION OF CO MONITORS CO poisoning can happen anywhere in a building. At the minimum, CO monitors should be located on every level of the building, near the persons who may be potentially affected by CO poisoning, and where workers can hear any alarm. More than one CO monitor may be required within different areas of the building.
SECTION 6, LOCATIONS TO AVOID, PRIOR TO INSTALLING YOUR CO MONITOR. ® The proper power for the Pro-Tech 8505 commercial CO monitor is a 9V battery. Constant exposure to high or low temperatures or humidity may reduce battery life. BATTERY INSTALLATION AND REPLACEMENT: Slide down and remove battery door, and attach a new 9 Volt alkaline battery (Duracell MN1604 or Energizer MAX 522) to the battery cable.
® In addition to the weekly test, the Pro-Tech 8505 CO monitor should be tested with a CO Detector Testing Aerosol at least once per year. Place an enclosure over the monitor, and follow the Aerosol’s instructions to perform the CO gas test correctly.

the unit, and it will not alarm if exposed to CO. See SECTION 14 for service information. SENSOR LIFE MONITOR: The electrochemical sensor has a life expectancy of 2 years, however, the monitor’s CO readings will decrease in accuracy after the first year. A microcontroller counts the total time that the CO monitor is under power.
The monitor maintains the 30 most recent days of peak CO level history, and the most recent TWA value. To manually erase the record, press the button DISPLAY MEMORY once, and while the readings are being displayed, press button once. TEST/RESET/MUTE The monitor will sound one short beep and will appear on the LCD display.

ability to hear the alarm. If you have a multi-level building, install CO monitors on each level. If the monitor is installed in a hallway and any office doors are kept closed, install a CO monitor in each room. If the monitor is installed in a large open area, one monitor should be installed for every 1000 square feet of vertically unobstructed space.
