- En cas d'alarme, évacuez immédiatement les lieux et contactez les services d'urgence.
5. Configuration et installation
The Gedsffati HD08-G detector is designed for simple plug-and-play installation.
- Choisissez un emplacement : Select an appropriate location for installation. For CO detection, place the unit at least 5 feet (1.5 meters) from any fuel-burning appliance. For combustible gas detection, place it near potential leak sources, but not directly above them. Avoid corners or areas with poor air circulation.
- Brancher: Insert the detector directly into a standard 110V-220V AC electrical outlet. The device will power on automatically.
- Auto-évaluation initiale : Upon plugging in, the detector will perform an initial self-test. The screen will illuminate, and you may hear a brief audible signal.
- Batterie de secours : The built-in 1000 mAh battery will begin charging once plugged in. This battery provides continuous operation during power outages and allows for portable use.


6. Mode d'emploi
Once plugged in and initialized, the detector continuously monitors the environment.
6.1 Affichage des informations

- CO (Carbon Monoxide): Displays the current CO concentration in parts per million (PPM).
- GAZ: Indicates the level of combustible gas detected, often represented by a bar graph or numerical value.
- Température: Affiche la température ambiante.
- Humidité: Displays the ambient humidity level.
- Indicateur de batterie : Affiche le niveau de charge actuel de la batterie.
- Brightness/Sound Icons: May indicate current settings for screen brightness and alarm sound.
6.2 Indications d'alarme

- When CO concentration exceeds 50ppm, or combustible gas levels exceed the alarm threshold, the detector will activate an audible alarm (85 dB) and the screen display will change, often with flashing indicators or color changes.
- Follow emergency procedures immediately upon alarm activation.
6.3 Fonction d'autotest

- To perform a self-test, short press the designated test button (often labeled 'H' or similar). The detector will briefly activate its alarm and display all indicators to confirm proper functioning.
- A green indicator light typically signifies normal operation, while a red light may indicate an alarm or sensor malfunction.
7. Entretien
Un entretien régulier garantit la longévité et la fiabilité de votre détecteur.
- Nettoyage: Essuyez délicatement l'extérieur du détecteur avec un chiffon doux et sec.amp cloth. Do not use harsh chemicals, abrasive cleaners, or spray directly onto the unit. Ensure no liquid enters the sensor openings.
- Tests réguliers : Perform a self-test at least once a week to confirm the alarm and display are functioning correctly.
- Vérification de la batterie : The built-in backup battery is designed for long-term use. If the detector frequently runs out of power during outages or the battery indicator shows low charge even after prolonged charging, the battery may be degrading. Contact customer support if you suspect a battery issue.
- Évitez les obstacles : Ensure that the detector's ventilation openings are not blocked by dust, debris, or household items.
8. Dépannage
If you encounter issues with your detector, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Le détecteur ne s'allume pas. | No power from outlet; unit not fully plugged in; backup battery depleted. | Ensure the outlet is functional. Plug the unit firmly into the outlet. Allow time for the backup battery to charge. |
| Alarm sounds frequently without apparent gas. | False alarm due to strong odors (e.g., cleaning products, aerosols); sensor contamination; actual low-level gas presence. | Ventilate the area. Move the detector to a different location temporarily. Clean the detector. If alarms persist, investigate potential gas leaks. |
| Display is blank or shows an error code. | Power issue; sensor malfunction; internal fault. | Check power connection. Perform a self-test. If the issue persists, contact customer support. |
| L'alarme est trop faible ou ne sonne pas. | Speaker obstruction; unit malfunction. | Ensure speaker is not blocked. Perform a self-test. If the alarm is still not audible, the unit may be faulty and requires replacement. |
If troubleshooting steps do not resolve the issue, please contact Gedsffati customer support for further assistance.
