4. Setup and Installation
4.1 Choosing a Location
Install smoke alarms in every sleeping room and outside each separate sleeping area. Install alarms on every level of a home, including the basement. For best protection, install an alarm in each room (except the bathroom and kitchen).
- Avoid installing near windows, doors, or areas with high airflow.
- Keep at least 10 feet (3 meters) away from cooking appliances.
- Mount on the ceiling in the center of the room, or on a wall at least 4 inches (10 cm) from the ceiling.
4.2 Mounting the Alarm
The alarm can be mounted using screws or adhesive tape.
- Using Screws:
- Mark two drill holes on the ceiling or wall using the mounting bracket as a template.
- Drill holes and insert the anchor plugs.
- Attach the mounting bracket using the provided screws.
- Align the alarm unit with the mounting bracket and twist clockwise until it clicks into place.
- Using Adhesive Tape:
- Ensure the mounting surface is clean, dry, and smooth.
- Peel off the protective film from the adhesive tape and firmly press the mounting bracket onto the desired location.

4.3 Interconnection (Pairing)
To interconnect multiple Sensereo wireless smoke alarms:
- Power on all alarms by attaching them to their mounting brackets. The LED indicator will flash.
- On one alarm (the master unit), press the test/hush button four times quickly. The LED will flash rapidly, indicating it's in pairing mode.
- Within 60 seconds, press the test/hush button twice quickly on each additional alarm you wish to pair. The LED on each additional alarm will flash rapidly, then briefly illuminate solid, indicating successful pairing.
- Once all alarms are paired, press the test/hush button on the master unit once to exit pairing mode.
- Test the interconnection: Press the test/hush button on any single alarm. All interconnected alarms should sound.
Note: The maximum transmission range between alarms is approximately 820 feet (250 meters) in open air. Obstacles like walls and floors will reduce this range.
5. Operating the Alarm
5.1 LED Indicator Status
- Green LED flashes once every 60 seconds: Normal operation.
- Red LED flashes rapidly with alarm sound: Smoke detected.
- Red LED flashes once every 60 seconds: Low battery warning (alarm will also chirp).
- Red LED flashes twice every 60 seconds: Fault indication.
5.2 Testing the Alarm
It is recommended to test your smoke alarm weekly:
- Press and hold the test/hush button for approximately 3 seconds.
- The alarm will sound a loud, pulsating siren, and the red LED will flash rapidly.
- If interconnected, all paired alarms should also sound.
- Release the button. The alarm will stop sounding.
Note: If the alarm does not sound during testing, refer to the Troubleshooting section.
5.3 Hush/Silence Feature
If a non-emergency condition (e.g., cooking fumes) causes the alarm to sound, you can temporarily silence it:
- Press the test/hush button once during an alarm.
- The alarm will silence for approximately 9 minutes. The red LED will continue to flash every 10 seconds to indicate it is in hush mode.
- After 9 minutes, if smoke is still present, the alarm will reactivate.
Caution: Do not use the hush feature for real fire situations. Always investigate the cause of an alarm.
6. Maintenance
6.1 Cleaning Your Smoke Alarm
Clean your smoke alarm at least once a month to remove dust and debris. Use a soft brush attachment on your vacuum cleaner to gently vacuum the outside of the alarm. Do not use water, cleaners, or solvents, as these can damage the unit.

6.2 Battery Information
This smoke alarm is equipped with a sealed 3V lithium battery designed to last for 10 years under normal operating conditions. The battery is not replaceable. When the battery is nearing the end of its life, the alarm will chirp once every 60 seconds, and the red LED will flash. This indicates that the unit needs to be replaced.
6.3 End of Life Indication
After approximately 10 years of operation, the alarm will indicate its end of life by chirping every 60 seconds, similar to a low battery warning. At this point, the entire smoke alarm unit must be replaced to ensure continued protection.
7. Troubleshooting
