2. Important Safety Information

WARNING: This carbon monoxide alarm is designed to detect carbon monoxide gas from any source of combustion. It is NOT designed to detect smoke or fire. This alarm is not a substitute for a smoke alarm. This device is not suitable for use in hazardous locations as defined in the National Electrical Code.

• Never ignore any alarm. Ignoring the alarm may result in serious injury or death.
• Test the detector weekly to ensure proper operation.
• Do not paint the detector. Paint can clog the openings and interfere with the sensor's ability to detect CO.
• Keep the detector away from direct sunlight, high humidity, and extreme temperatures.
• Do not install in areas with high air velocity, such as near vents, fans, or open windows, as this can affect detection accuracy.

4.2 Battery Installation

The detector requires three (3) AA 1.5V alkaline batteries. Ensure batteries are installed correctly according to polarity markings inside the battery compartment.

1. Twist the back cover of the detector counter-clockwise to open the battery compartment.
2. Insert three AA 1.5V alkaline batteries, matching the (+) and (-) terminals.
3. Close the battery compartment by aligning the cover and twisting clockwise until secure.

4.3 Mounting the Detector

You can choose between screw mounting or magnetic adhesive mounting.

Image: Illustration of two installation methods: (1) using magnetic pads for easy attachment to a surface, and (2) using screws and anchors for a more permanent fixture.

Screw Mounting:

1. Select a suitable location (see 4.4 Placement Recommendations).
2. Mark the positions for the two mounting holes on the wall or ceiling using the detector's base as a template.
3. Drill two holes and insert the provided wall anchors.
4. Secure the mounting bracket to the wall/ceiling with the provided screws.
5. Attach the detector to the mounting bracket by twisting it clockwise until it clicks into place.

Magnetic Adhesive Mounting:

1. Ensure the mounting surface is clean, dry, and smooth.
2. Peel the protective film from one side of the magnetic adhesive pad and firmly attach it to the back of the detector.
3. Peel the protective film from the other side of the magnetic adhesive pad.
4. Press the detector firmly against the desired wall or ceiling location for at least 30 seconds.

4.4 Placement Recommendations

For optimal performance and safety, consider the following:

• Install at least one CO detector on each level of your home, especially near sleeping areas.
• Place detectors at least 5 feet (1.5 meters) away from fuel-burning appliances to avoid nuisance alarms.
• Mount on a wall about 5 feet (1.5 meters) from the floor, or on the ceiling.
• Avoid placing in garages, kitchens, or bathrooms where high humidity or exhaust fumes could trigger false alarms or damage the sensor.

5. Operation

5.1 Power-On and Initial Test

After battery installation, the detector will perform a self-test. The LED indicators will flash, and the alarm may sound briefly. This indicates the unit is functioning correctly.

5.2 LED Indicators

5.3 Test / Silence Button

The large central button serves two functions:

• Test Function: Press and hold the button for a few seconds to test the alarm. The alarm will sound, and the red ALARM LED will flash. Release the button to stop the test. Perform this test weekly.
• Silence Function: During a CO alarm, pressing the button will temporarily silence the audible alarm for a period (e.g., 5 minutes). The red ALARM LED will continue to flash. If CO levels remain high, the alarm will reactivate after the silence period. For low battery warnings, the silence function may last up to 48 hours.

5.4 Alarm Conditions

When carbon monoxide is detected at dangerous levels, the detector will emit a loud 85dB alarm sound, and the red ALARM LED will flash rapidly. Follow these steps if the alarm sounds:

1. Immediately move to fresh air outdoors or open all doors and windows to ventilate the area.
2. Do a head count to check that all persons are accounted for.
3. Do not re-enter the premises until the alarm has stopped and the area has been thoroughly ventilated.
4. Call the fire department or a qualified technician to investigate the source of CO.

6. Maintenance

6.1 Weekly Testing

Test your CO detector weekly by pressing and holding the Test/Silence button until the alarm sounds. This confirms the electronic circuitry, alarm, and battery are working.

6.2 Cleaning Your Detector

Clean the detector regularly to prevent dust and debris from accumulating and affecting its performance.

• Use a soft, damp cloth to wipe the exterior of the detector.
• Do not use cleaning solvents or chemicals, as they can damage the sensor.
• Do not spray air fresheners, hair spray, or other aerosols near the detector.

6.3 Battery Replacement

When the detector's batteries are low, the yellow STATUS LED will flash, and the unit will chirp periodically. Replace all three AA 1.5V alkaline batteries immediately. Refer to section 4.2 for battery installation instructions.

6.4 End-of-Life Indication

The SITERWELL Carbon Monoxide Detector has a 7-year product life. After approximately 7 years from the date of manufacture, the unit will indicate its end-of-life by a specific chirp pattern or LED sequence. At this point, the entire unit must be replaced.
