1. Introduction
The ELRO FZ5010R interconnected smoke detector is designed to provide early warning in the event of a fire. This device can be wirelessly linked with other FZ5010R detectors. When one detector senses smoke, all connected detectors will sound an alarm, ensuring comprehensive coverage and timely notification throughout your property.
Equipped with a 10-year lithium battery, this detector offers long-term protection without the need for frequent battery replacement. Its high-quality optical sensor ensures quick response to fire while minimizing false alarms. The ELRO FZ5010R complies with the European standard EN14604 for smoke detectors.
Key Features:
- Wireless interconnection with up to 40 other ELRO FZ5010R smoke detectors.
- Integrated 10-year lithium battery for maintenance-free operation.
- Durable optical sensor for rapid smoke detection and reduced false alarms.
- Test button for easy function verification.
- Low battery indicator for timely replacement alerts.
- Loud 85dB alarm signal.

3. Important Safety Information
- This smoke detector is designed for residential use.
- Do not paint the smoke detector. Paint can block the smoke entry points and interfere with the sensor's operation.
- Do not use detergents or cleaning solvents on the detector. Clean only with a vacuum cleaner or a soft, dry cloth.
- The integrated battery is not replaceable. The detector must be replaced after 10 years of operation.
- Test the smoke detector monthly to ensure proper function.
- Ensure the alarm is audible from all sleeping areas.
- This device is not a substitute for proper fire safety practices, such as regular fire drills and having a fire extinguisher.
4. Setup and Installation
4.1 Battery Activation
The ELRO FZ5010R features an integrated 10-year battery that activates automatically upon installation. Once the detector is twisted onto its mounting plate, the battery will engage, and the device will be ready for use. The battery is designed to last for the entire 10-year lifespan of the smoke detector.

4.2 Choosing an Installation Location
For optimal protection, install at least one smoke detector on each floor of your home, including hallways, landings, and stairwells, as these are part of your escape route. Always install the smoke detector on the ceiling.

4.3 Mounting the Detector
- Select a suitable ceiling location, away from corners, vents, and light fixtures.
- Use the provided mounting hardware (screws and wall plugs) to securely attach the mounting plate to the ceiling.
- Align the smoke detector with the mounting plate and twist it clockwise until it clicks into place. This action will activate the internal battery.

4.4 Wireless Interconnection (Pairing)
The FZ5010R detectors can be wirelessly interconnected, allowing all linked detectors to alarm simultaneously if one detects smoke. Up to 40 detectors can be paired.
- Take the first smoke detector. Press its large test button three times in quick succession to enter pairing mode.
- Within a short time, take the second smoke detector and press its test button three times in quick succession.
- The back of both smoke detectors will illuminate with a green light, indicating successful pairing.
- Repeat this process for any additional detectors you wish to interconnect.

5. Operating the Smoke Detector
5.1 Normal Operation
Once installed and activated, the smoke detector continuously monitors for smoke. A small LED indicator on the detector will flash periodically (e.g., every 40-60 seconds) to confirm it is functioning correctly.
5.2 Testing the Detector
It is crucial to test your smoke detector monthly to ensure it is working properly. Press and hold the large test button on the front of the detector for a few seconds. The alarm will sound loudly (85dB), and the LED will flash rapidly. Release the button to stop the alarm. If the alarm does not sound, refer to the troubleshooting section.
5.3 Alarm Behavior
When smoke is detected, the detector will emit a loud, piercing alarm sound (85dB) and the LED indicator will flash rapidly. If interconnected, all paired detectors will also sound their alarms. Take immediate action according to your fire escape plan.
5.4 Low Battery Indication
When the integrated 10-year battery is nearing the end of its life, the detector will emit a short 'chirp' sound approximately once every 30-40 seconds. This indicates that the detector needs to be replaced. The entire unit must be replaced, as the battery is not user-replaceable.
6. Maintenance
Regular maintenance ensures the optimal performance and longevity of your smoke detector.
6.1 Cleaning
Dust and debris can accumulate in the smoke chamber, potentially causing false alarms or hindering detection. Clean your smoke detector at least once a month:
- Gently vacuum the exterior of the detector, especially around the smoke entry points.
- Use a soft, dry cloth to wipe the surface.
- Do not use any liquid cleaners, sprays, or detergents, as these can damage the sensor or internal components.
6.2 Regular Testing
As mentioned in the operating section, test your smoke detector monthly by pressing the test button. This confirms the alarm and internal circuitry are functioning correctly.
7. Troubleshooting
If your ELRO FZ5010R smoke detector is not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector chirps every 30-40 seconds. | Low battery. | The 10-year battery is at the end of its life. Replace the entire smoke detector unit. |
| Detector does not alarm when test button is pressed. | 1. Battery not activated. 2. Detector malfunction. | 1. Ensure the detector is properly twisted onto its mounting plate to activate the battery. 2. If still no alarm, the detector may be faulty. Replace the unit. |
| False alarms occur frequently. | 1. Dust or debris in the smoke chamber. 2. Detector too close to cooking fumes, steam, or high humidity. | 1. Clean the detector as described in the maintenance section. 2. Relocate the detector to an area less prone to false alarm triggers. |
| Interconnected detectors do not all alarm. | Pairing issue or range limitation. | Re-pair the detectors following the steps in section 4.4. Ensure detectors are within effective wireless range (up to 35m in open space). |
