Engineered for swift integration into domestic environments, residential building networks, and commercial multi-family housing complexes across America.
The safety landscape for residential housing in the United States is experiencing a profound transition. As state legislatures move towards proactive mitigation of fuel gas leaks, new compliance standards are becoming mandatory. For example, legislative actions like New York State's Senate Bill S3235 and similar ordinances in Maine and Connecticut require the installation of combustible gas detectors in residential structures containing natural gas or propane systems.
Unlike traditional fire alarms, modern residential gas detectors must offer long-term sensor stability, zero drift, and resistance to environmental contaminants such as household cleaners and aerosol sprays. Compliance with UL 1484 (Standard for Residential Gas Detectors) and NFPA 715 (Standard for the Installation of Combustible Gas Detection Devices) is now a central criterion for procurement by North American HVAC distributors, multi-family housing developers, and municipal utility providers.
At Xinhaosi, we align our R&D with these strict regulatory shifts, supplying robust, highly selective sensor architectures that protect families and property while minimizing nuisance false alarms.

Explore our foundational residential and multi-point gas safety line, designed for developers, distributors, and global OEM partners.
From advanced SMT lines to our ISO/IEC 17025 accredited calibration lab, quality control is integrated into every phase of production.
Deyang Intelligent Manufacturing Factory
Established in 2003, Xinhaosi has spent two decades building a global reputation in the safety industry. Integrating research, design, production, and service, we supply gas safety technology to global markets, including North America, Europe, and the APAC region.
Our core production is backed by the ISO9001 Quality Management System, alongside certifications including CE, SIL, and localized national approvals. By running an in-house laboratory accredited by the China National Accreditation Service for Conformity Assessment (CNAS), operating under the ILAC-MRA framework, we guarantee that all performance and calibration data is traceable to international reference standards.
Our intelligent factories in Chengdu and Deyang feature automated SMT placement, advanced environmental simulation test chambers, and precision gas-mixing equipment. These tools enable us to test every product under extreme conditions, including varying humidity and temperature extremes, before shipment.
Innovation is key to protecting life and property. Xinhaosi holds over 50 patents and software copyrights. Our R&D team pioneered networked bus-type monitoring configurations and software platforms that enable predictive maintenance. By analyzing sensor drift and output cycles, our systems can help reduce equipment failures by up to 30%.
We are also active contributors to safety standards, acting as a primary drafting unit for national standards in solenoid valve technology and flow-integrated detection equipment. This industry leadership helps keep our technology aligned with emerging global compliance demands.
