1. Einleitung
This manual provides important information regarding the installation, operation, and maintenance of your Generic Portable Carbon Monoxide Detector, Model JSN-997. This device is designed to detect carbon monoxide (CO) gas and alert you to potentially dangerous levels, helping to protect your family from the invisible threat of CO poisoning. Please read this manual thoroughly before using the detector and retain it for future reference.
2. Sicherheitshinweise
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to alert you to the presence of CO. However, it is not a substitute for proper maintenance of fuel-burning appliances or ventilation systems.
Wichtige Sicherheitshinweise:
- UL 2034-Konformität: This carbon monoxide alarm is rigorously tested and certified to meet UL 2034 standards for reliable detection.
- Nicht behindern: Ensure the detector's vents are not blocked by furniture, curtains, or other objects.
- Testen: Do not use gas or any other substance to directly blow into the detector's sensing hole when testing. Use the designated test button.
- Alarmreaktion: If the alarm sounds, immediately move to fresh air, call emergency services, and do not re-enter the premises until it has been deemed safe by professionals.
Understanding CO Dangers:
Carbon monoxide exposure can lead to various health effects depending on concentration and exposure time. The detector is programmed to alarm at specific CO levels and durations:

This image illustrates the CO concentration levels and the corresponding timeframes within which the alarm will be triggered.

This infographic highlights the potential health effects of carbon monoxide exposure at various concentrations.

Empfohlene Platzierung:
For optimal protection, it is recommended to install a CO detector on each level of your home and in each bedroom. Consider placing detectors near sleeping areas and areas where fuel-burning appliances are located. The detector can be mounted on a wall or placed on a flat surface.

This image shows recommended top or side mounting and highlights key features.

This image demonstrates the versatility of placement to protect every corner of the home.
5. Bedienungsanleitung
Normalbetrieb:
During normal operation, the detector continuously monitors CO levels. The LCD digital display will show the current CO concentration in parts per million (PPM) or temperature. A green light will flash approximately every 30 seconds to indicate proper functioning.
Testen des Detektors:
Regular testing ensures your detector is functioning correctly. Press the Test/Reset button firmly. The screen will light up, the red light will flash, and the alarm will sound. This confirms the alarm and display are working. The screen will then go off, and the green light will resume flashing every 30 seconds.

Press the test button to verify alarm functionality.
Alarmanzeigen:
The detector uses visual indicators to communicate its status:
- Grünes Licht: Indicates power and normal operation.
- Rotlicht: Zeigt einen CO-Alarmzustand an.
- Gelbes Licht: Weist auf einen Fehler oder einen niedrigen Batteriestand hin.

Visual indicators for Power, Alarm, and Fault status.
6. Wartung
Regelmäßige Tests:
Test your CO detector weekly by pressing the Test/Reset button to ensure the alarm and display are functioning correctly.
Batteriewechsel:
When the batteries are low, the yellow fault light may illuminate, and the detector might emit a chirp. Replace both AAA batteries promptly following the instructions in Section 4.1.
Reinigung:
Gently clean the exterior of the detector with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Do not paint the detector, as this can interfere with the sensor's operation.
