Combustible gas and carbon monoxide are different hazards, so the alarm must match the substance being monitored. Garrison lists the LK-680N gas alarm, CX-96RN CO alarm and CX-97RN combined CO/gas alarm. A gas-only model should not be treated as a carbon monoxide detector.
The LK-680N product description identifies LPG/LNG detection. For CO monitoring or combined coverage, review the corresponding model documentation rather than applying LK-680N specifications to other products. Confirm the gas types, power requirements and alarm functions of the exact model before purchase.
Placement depends on the hazard, room conditions and manufacturer guidance. Request the current manual and relevant destination-market documentation, including any applicable test or certification records. A statement about a standard on a product page is not proof of certification for the entire range.
Provide Garrison with the target gas, installation location, power supply, destination country and quantity. Alarms supplement appropriate installation, ventilation and maintenance; they do not prevent leaks or guarantee safety.
