Introduction
The CPVAN Interlinked Wireless Smoke Detector is designed to provide early warning of fire by detecting smoke particles. This device features a 10-year sealed battery and wireless interlinking capabilities, allowing multiple detectors to communicate and trigger a synchronized alarm throughout your home. This manual provides essential information for the proper installation, operation, and maintenance of your smoke detector.
Product Overview

The smoke detector features the following key components:
- Horn: Emits a loud alarm sound when smoke is detected.
- Test/Silence Button: Used to test the detector's functionality and to silence false alarms.
- LED Indicator: Provides visual status of the detector (e.g., standby, alarm, low battery).

The detector has a diameter of 125mm and a thickness of 27mm. It is constructed from fire-resistant ABS material and produces an alarm volume of over 85dB at 3 meters.

Setup and Installation
1. Unpacking and Initial Check
Carefully remove the smoke detector from its packaging. Ensure all components are present and undamaged.
2. Interlinking Multiple Detectors (if applicable)
CPVAN CP-SD01 (FSI-3001) smoke detectors are pre-linked at the factory. If you have multiple units, they should already be able to communicate. If you need to add new detectors or re-establish communication, follow these steps:
- To Emit Signal: Press the Test/Silence button on the first detector 4 times quickly.
- To Receive Signal: Press the Test/Silence button on the second detector 2 times quickly.
- Repeat for all detectors you wish to interlink. A maximum of 30 wireless smoke detectors can be networked together.


3. Choosing a Mounting Location
For optimal protection, install smoke detectors:
- On every level of your home, including the basement.
- Inside every sleeping area.
- In the hallway outside of every separate sleeping area.
- Avoid installing in kitchens, bathrooms, or near heating vents, as steam or cooking fumes can cause false alarms.
4. Mounting the Detector
The detector can be installed on any wall or ceiling using the provided screws and magnetic holder.

- Drill Holes: Mark the desired location on the ceiling or wall and drill two holes for the mounting bracket.
- Fix Bracket with Screws: Secure the mounting bracket to the drilled holes using the provided screws.
- Turn to Lock: Align the smoke detector with the mounted bracket and turn it clockwise until it locks securely into place.
Alternatively, use the magnetic holder for easier installation:
- Attach one part of the magnetic holder to the wall/ceiling.
- Attach the other part of the magnetic holder to the back of the smoke alarm.
- Simply connect the two magnetic parts to secure the alarm.
Operation
1. Power On
The smoke detector is equipped with a sealed 10-year lithium battery and is automatically powered on once installed. No manual power-on is required.
2. Status Indicator
In standby mode, the green LED indicator will blink extremely weakly every 300 seconds to confirm the detector is operational. This dim flash is designed not to disturb you, especially during sleep.

3. Alarm Activation
When smoke is detected, the detector will emit a loud alarm sound (>85 dB) and the red LED will flash brightly. If multiple detectors are interlinked, all connected alarms will activate simultaneously, ensuring widespread notification.

4. Test/Silence Function
- Testing: Press and hold the Test/Silence button for a few seconds. The alarm should sound, and the red LED should flash. Release the button to stop the test.
- Silencing: In case of a false alarm (e.g., from cooking fumes), press the Test/Silence button once to temporarily silence the alarm. The detector will reset after a few minutes if no further smoke is detected.
Maintenance
1. Regular Testing
It is recommended to test your smoke detector weekly or monthly by pressing the Test/Silence button. This ensures the alarm and internal circuitry are functioning correctly.
2. Cleaning
Dust and debris can accumulate in the smoke chamber, potentially affecting sensitivity or causing false alarms. Clean your smoke detector at least once a month:
- Gently vacuum around the vents and openings of the detector using a soft brush attachment.
- Wipe the exterior with a clean, damp cloth. Do not use cleaning solvents or sprays.
3. Battery Life
The detector is equipped with a 10-year sealed lithium battery that is non-replaceable. When the battery reaches a low voltage (2.7 ± 0.1 V), the detector will emit a low battery warning (typically a chirp every 30-60 seconds). When this occurs, the entire unit must be replaced.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm sounds without visible smoke. | Dust accumulation, steam from shower, cooking fumes, high humidity. | Press the Test/Silence button. Clean the detector. Relocate the detector away from sources of steam or fumes if false alarms persist. |
| Detector chirps every 30-60 seconds. | Low battery warning. | The battery is sealed and non-replaceable. The entire smoke detector unit needs to be replaced. |
| Detector does not sound during test. | Unit malfunction or end of life. | Ensure the button is pressed firmly. If it still doesn't sound, the unit may be faulty or at the end of its 10-year lifespan and needs replacement. |
| Interlinked alarms do not all sound. | Detectors are out of range, or interlinking was not properly established. | Ensure all detectors are within the 100-meter operating range. Re-perform the interlinking procedure (press 4 times to emit, 2 times to receive) for all units. |
User Tips
- Regular Testing is Crucial: Make it a habit to test your smoke detectors monthly. This simple check can save lives.
- Strategic Placement: Install detectors on every floor of your home, especially in hallways leading to bedrooms and inside bedrooms themselves, to maximize early warning.
- Avoid Nuisance Alarms: While smoke detectors are vital, placing them too close to cooking appliances or steamy bathrooms can lead to false alarms. Consider placement carefully.
- Know Your Escape Plan: In addition to having working smoke detectors, ensure everyone in your household knows what to do and where to go in case of a fire.
