3. Important Safety Information

Carbon monoxide (CO) is an odorless, colorless, and toxic gas. Exposure to CO can be fatal. This detector is designed to alert you to the presence of CO, but it is not a substitute for proper ventilation and maintenance of fuel-burning appliances.

Warning: Never ignore an alarm. Investigate the cause immediately. If the alarm sounds, evacuate the premises and call emergency services.

4. Setup and Installation

4.1 Package Contents:

• Linsoal Combination Smoke and CO Detector (quantity as purchased)
• User Manual
• AAA Batteries (9 batteries for a 3-pack)
• Mounting Screws and Anchors

4.2 Choosing a Location:

Install the detector in areas where smoke and CO are most likely to be detected, such as near sleeping areas and living rooms. For optimal smoke detection, install on the ceiling or high on a wall. For CO detection, it can be installed at any height, but typically at eye level for easy viewing of the LCD display.

• Install at least 4 inches (10 cm) from walls if mounting on the ceiling.
• If mounting on a wall, the top of the alarm should be between 4 and 12 inches (10-30.5 cm) from the ceiling.
• Avoid installing near windows, doors, or areas with high airflow, as this can affect sensor accuracy.
• Do not install in kitchens, bathrooms, or garages where steam, cooking fumes, or vehicle exhaust could cause false alarms.

4.3 Installation Steps:

1. Prepare Mounting Location: Choose a suitable location according to the guidelines above.
2. Install Batteries: Open the battery compartment and insert the AAA batteries, ensuring correct polarity.
3. Mount Bracket: Use the included screws and anchors to securely attach the mounting bracket to the wall or ceiling.
4. Attach Detector: Align the detector with the mounting bracket and twist clockwise until it locks into place.
5. Test Unit: Press the "TEST/SILENCE" button to confirm proper operation. The alarm should sound, and the LCD display should activate.

5. Operating Instructions

5.1 Power-Up Sequence:

Upon initial power-up or battery replacement, the unit will emit a "chirp" sound, and the red LED will flash once. The LCD display will show "000 PPM" briefly.

5.2 Normal Operation:

In normal operating conditions, the LCD display is not lit. The green LED indicator will flash approximately every 40 seconds to confirm the unit is functioning correctly.

5.3 Alarm Indications:

• Smoke Alarm: Continuous beeps. The red LED will flash rapidly.
• CO Alarm: Four short alarm beeps, repeated. The LCD display will show the detected CO concentration in PPM. The red LED will flash.

5.4 Test/Silence Button:

Press the "TEST/SILENCE" button to perform a self-test of the unit. During an alarm, pressing this button will temporarily silence the alarm for a short period (typically 5-10 minutes for smoke, or a shorter period for CO depending on concentration), allowing you to investigate the cause. If the hazard persists, the alarm will reactivate.

6. Maintenance

6.1 Regular Testing:

Test your detector weekly by pressing the "TEST/SILENCE" button. Ensure the alarm sounds and the display functions correctly.

6.2 Battery Replacement:

The detector will indicate a low battery condition by displaying "Lb" on the LCD screen and emitting a chirp sound periodically. Replace all batteries immediately when this occurs. It is recommended to replace batteries every 3 years, or as indicated by the low battery warning.

6.3 Cleaning:

Dust and debris can affect the detector's performance. Gently vacuum the exterior of the alarm with a soft brush attachment at least once a month. Do not paint the unit or use cleaning solvents.
