1. Introduction
The First Alert BRK SMCO100 is a battery-operated combination smoke and carbon monoxide (CO) alarm designed to provide early warning of both smoke and CO presence. This device utilizes Precision Detection advanced sensing technology to reduce nuisance alarms while ensuring reliable detection. It is intended for residential use to help protect occupants from the dangers of fire and carbon monoxide poisoning.
2. Setup and Installation
Proper installation is crucial for the effective operation of your alarm. Follow these steps carefully.
2.1 Unpacking and Battery Installation
- Carefully remove the alarm and all components from the packaging.
- Locate the battery compartment on the back of the alarm.
- Insert the included 9V alkaline battery, ensuring correct polarity (+ and -). The alarm may chirp briefly upon battery insertion.

2.2 Mounting Location
For optimal protection, install smoke and CO alarms on every level of your home, including basements, and in every bedroom. Avoid installing near windows, doors, or vents where drafts could interfere with detection. Do not install in kitchens or bathrooms where steam or cooking fumes could cause nuisance alarms.

4. Maintenance
Regular maintenance ensures the continued reliability of your alarm.
4.1 Battery Replacement
Replace the 9V battery immediately when the alarm chirps once every minute, indicating a low battery. Refer to Section 2.1 for battery installation instructions.
4.2 Cleaning
Clean your alarm regularly to prevent dust and debris from interfering with its operation. Use a soft brush attachment on your vacuum cleaner to gently remove dust from the alarm's vents. Do not paint the alarm or use cleaning solvents.
4.3 Regular Testing
Test your alarm weekly by pressing and holding the Test/Silence button until the alarm sounds. This confirms the electronic circuitry and horn are functioning correctly.
5. Troubleshooting
If your alarm is not functioning as expected, consult the following common issues.
- Alarm chirps once every minute: The battery is low and needs to be replaced.
- Alarm sounds intermittently without smoke or CO: This may be a nuisance alarm. Ensure the alarm is not installed near cooking fumes, high humidity areas, or strong drafts. Press the Test/Silence button to temporarily silence it.
- Alarm does not sound during test: Ensure the battery is correctly installed and fully charged. If the issue persists, the unit may need replacement.
- Alarm sounds continuously: Evacuate the premises immediately and call emergency services. Do not re-enter until authorities have deemed it safe.
