VIGAS uses MEMS semiconductor sensor technology designed for stable detection of natural gas, primarily methane. The sensor continuously monitors the surrounding air during normal operation. Sensor technology is only one component of overall product performance. Alarm threshold, product listing, installation location, environmental conditions and manufacturer instructions must also be considered when selecting and installing a […]

VIGAS provides an audible alarm rated at 85 dB at 10 feet, together with visual LED indicators. The combination of audible and visual warning is designed to provide clear status communication when the device detects a hazardous natural gas concentration or communicates device status. For complete alarm and indicator behavior, refer to the current VIGAS […]

VIGAS triggers its audible and visual warning at 10% of the Lower Explosive Limit (LEL) for methane. The Lower Explosive Limit represents the concentration at which a fuel-gas and air mixture can begin to become ignitable. A 10% LEL alarm threshold is therefore designed to provide warning before methane reaches the Lower Explosive Limit. The […]

VIGAS is designed and documented as a natural gas alarm for methane detection. It should not be selected as a propane alarm unless the current product documentation specifically confirms suitability for that application. When selecting any gas alarm, the device specification should match the fuel gas that needs to be detected. For current VIGAS specifications, […]

No. VIGAS is not a smoke alarm. It is designed for residential natural gas detection, primarily methane. Smoke alarms, carbon monoxide alarms and natural gas alarms perform different detection functions and should not be treated as interchangeable devices. Property owners should review all applicable life-safety requirements for the building rather than assuming that one type […]

No. VIGAS is a natural gas alarm, primarily designed to detect methane. It does not replace a carbon monoxide alarm. Carbon monoxide and natural gas represent different hazards: natural gas alarms detect leaking fuel gas before combustion; carbon monoxide alarms detect CO produced by incomplete combustion. Properties containing gas-burning appliances may therefore need both natural […]

VIGAS detects natural gas, primarily methane (CH4). Methane is the principal component of the natural gas commonly supplied to residential buildings. VIGAS continuously monitors for methane and activates its audible and visual warning when the detection threshold is reached. VIGAS should not be treated as a universal combustible-gas detector. Product selection should always be based […]

VIGAS is a standalone residential natural gas alarm manufactured by NEXELEC. The alarm continuously monitors the surrounding air for natural gas, primarily methane. If the detected methane concentration reaches the alarm threshold, VIGAS provides audible and visual warning. VIGAS is designed as a self-contained alarm with an integrated sealed lithium battery, meaning it does not […]

VIGAS is covered by a 2-year limited warranty from the date of purchase. The 10-year service life is not a 10-year warranty.

VIGAS is an ETL Listed residential natural gas alarm that conforms to UL 1484. Compliance also depends on the building, installation location and applicable New York City requirements. Always follow the User Guide and NYC Department of Buildings instructions.

VIGAS is ETL Listed by Intertek and conforms to UL 1484, the applicable standard for residential natural gas alarms.

VIGAS detects natural gas, primarily methane. It does not detect carbon monoxide, smoke or propane.
