WHAT YOU SHOULD KNOW ABOUT CO Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ damage in unborn infants with no effect on the mother. 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).

• An alarm should be installed in any family living unit containing a fuel-burning appliance or fireplace or having an attached garage. • An alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. Where bedrooms are separated and audibility of the alarm to occupants within the bedroom area could be seriously impaired, more than one alarm could be needed. • Locate the first combination alarm in the immediate area of the bedrooms.
PAGE 4
NOTE: For any location, make sure no door or other obstruction could prevent the carbon monoxide or gas from reaching the alarm. WHERE THIS ALARM SHOULD NOT BE INSTALLED To avoid causing damage to the unit, to provide optimum protection, and to prevent unnecessary alarms. Do NOT locate this alarm: • In garages, kitchens, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas.
PAGE 5
THIS ALARM WILL NOT WORK WITHOUT 120 VAC POWER AND A GOOD BATTERY PROPERLY INSTALLED. THE ALARM SHOULD BE TESTED WHEN INSTALLED AND THEN TESTED WEEKLY AFTER THAT. INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY. Installation of this alarm must conform to the electrical codes in your area; Article 760 of the National Electrical Code, NFPA 72, 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA): OTFDC (CABO), and any other local or building codes that may apply.

b. c. Turn off AC power to the circuit before wiring the alarm. There are three pigtail wires (black, white and yellow) coming from the AC QUICK CONNECTOR. The proper wire connection is as follows: WIRES FROM QUICK CONNECTORCONNECT TO BLACK "HOT" side of AC line WHITE "NEUTRAL" side of AC line YELLOW Interconnect wires of other alarms DO NOT TAMPER WITH WIRES WHEN POWER IS ON! For alarms that are used as single non-interconnected, stand-alone alarms, do not connect the yellow wire to anything.
PAGE 7
120 VAC 60Hz 100mA Max. The yellow wire is used only for multiple station operations with USI ELECTRIC or UNIVERSAL Model alarms only. Connecting this yellow wire to any other circuits may result in damage and alarm malfunction. When alarms are interconnected, all alarms must be powered from a single AC branch circuit. If local codes do not permit, be sure the neutral wire is common to both phases.
PAGE 8
TROUBLE / SERVICE ALARM: Periodically, the alarm measurement circuit is tested. If an error is detected, the alarm will sound 3 chirps approx. every 20 seconds. Reset the alarm. If the unit does not reset, replace the alarm. END-OF-SERVICE LIFE ALARM: When it is time to replace your alarm, which is approximately 7 years of operation from initial power up, the alarm will sound 2 chirps approx. every 20 seconds. Replace alarm immediately.
PAGE 9
WHAT TO DO IF NATURAL GAS IS DETECTED: If you hear the alarm horn sound approx. 1 beep, 2 second pause, repeat, gas has been detected. Evacuate everyone from the building. 1. Leave the house immediately, opening doors and windows as you leave. 2. Do not use your telephone or appliances. Do not turn any light switches off or on. Any spark or flame could ignite the gas. 3. Call 911 and your gas company from a phone that is away from your home. 4.
PAGE 10
WEEKLY TESTING This alarm is designed to act as a monitor, not for use as a short-term testing device, to perform a quick check for the presence of CO or gas. WARNING: Natural gas (methane) is highly explosive. An attempt to test the unit by exposing it to natural gas outside of a controlled labatory environment can produce an explosion and death. NEVER use a gas range or an open flame of any kind to test this alarm. You might accidentally damage or set fire to the alarm or to your home.
PAGE 11
CO AND NATURAL GAS ALARM LIMITATIONS Alarms have limitations. Like any other electronic device, CO and Natural Gas alarms are not foolproof. CO and Natural Gas alarms have a limited operational life. Your alarm must be tested weekly, because it could fail to operate at any time. If your Alarm fails to test properly, or if its self-diagnostic test reveals a malfunction, immediately have the unit replaced (see last page for warranty information).
