The Nexelec VIGAS (K987GL) is a residential natural gas alarm that continuously monitors indoor air for methane and triggers a powerful audible and visual alert when gas is detected. VIGAS operates on a sealed lithium battery designed to last the full 10-year service life of the detector — no battery replacement required. Listed to UL 1484, VIGAS is designed for single-family homes, multi-family housing, student residences, and managed property portfolios equipped with natural gas. A QR code and NAVIXIS software platform simplify installation tracking and fleet management across large deployments. Key Features Methane detection: MEMS thermoelectric semiconductor sensor continuously monitors for the presence of natural gas (methane) in residential indoor environments. Triggers an alarm at just 10% of the Lower Explosive Limit (LEL) — early warning before methane reaches dangerous concentrations. 85 dB audible alarm: Powerful alarm at 10 ft (3 m) to quickly warn occupants when gas is detected. Three-color LED indicators: Clear visual status indication — normal operation, alert, fault, or maintenance information readable directly from the front of the product. Test/control button: Integrated button allows occupants to verify the detector is functioning correctly at any time. 10-year sealed battery: Sealed lithium battery designed for the full service life of the detector. No battery replacement required. Low battery alert notifies users when voltage becomes too low. Digital logbook: QR code on each detector links to an online logbook tracking installation, maintenance, and replacement history. Integrates with the NAVIXIS software platform for fleet management across multiple properties. UL 1484 listed: Listed to UL 1484 standard for residential natural gas detection — a recognized compliance benchmark for residential safety equipment in the United States. Compact wall-mount design: Simple installation near gas sources. Mounting screws and wall anchors included. Applications Natural gas safety in single-family homes and apartments with gas appliances Multi-family residential buildings requiring UL 1484 listed gas detection NYC Local Law 157 compliance for natural gas detection in residential buildings Student housing, senior residences, and managed residential portfolios Large-scale fleet deployment and tracking via NAVIXIS digital logbook Important Notes VIGAS detects methane (natural gas) only. It is not a carbon monoxide (CO) alarm and does not detect CO produced by incomplete combustion. VIGAS is a standalone gas alarm and is not a substitute for other required safety devices. Installation requirements vary by building type and local regulations — always verify applicable codes before installation. Install near gas appliances and sources per the instructions in the user manual and applicable local codes. Do not install in locations with excessive humidity, grease, or dust. The sealed battery is designed for the 10-year service life of the detector. Battery replacement is not supported. Replace the detector at end of life. Operating range: 0°C to +50°C (32°F to 122°F), 5% to 93% RH non-condensing. Indoor use only.
