Product Detail

The JT-CA319N+DN15 Valve is a high-end residential combustible gas safety system integrating 4G remote monitoring, intelligent detection, audible and visual alarms, automatic valve shut-off, and linked ventilation. Designed specifically for homes using piped natural gas, it provides a complete solution from detection and early warning to emergency response. When the detector detects excessive methane concentration, it not only issues a strong audible and visual alarm on-site but also instantly pushes the alarm information to the user's mobile phone via the 4G network. Simultaneously, the device automatically shuts off the gas valve and activates the ventilation system, proactively eliminating the hazard. This completely solves the pain points of traditional alarms that "only sound an alarm but do not respond" and lack remote notification capabilities, providing you and your family with 24/7, all-around proactive safety protection.

4G Remote Monitoring, Unrestricted Network

Built-in 4G IoT module, eliminating reliance on home Wi-Fi and providing stable signal coverage. Receive alarm information anytime, anywhere via mobile app/IoT platform, remotely monitor device status, and enjoy peace of mind even when away from home.

Dual Safety Linkage, Proactive Protection

Upon detecting a methane leak, an audible and visual alarm is immediately triggered, and a signal is simultaneously output to automatically shut off the solenoid valve, cutting off the gas supply at its source. Simultaneously, a powerful exhaust fan is activated for strong ventilation, creating a dual safety barrier of "valve shutdown + ventilation."

Specialized in Methane, Rapid Response

Utilizes a high-performance semiconductor sensor optimized for methane (natural gas) detection, with a response time of <20 seconds, quickly identifying leak risks and buying valuable time for home safety.

Industrial-Grade Protection, Home-Grade Operation

ABS material combined with anti-static, anti-oil fume, and anti-alcohol design, it withstands the complex environment of a kitchen, effectively preventing false alarms and missed alarms. Intelligent design, simple operation, and professional protection upon installation.

Choosing the JT-CA319N means choosing a new generation of smart home security standards. We offer not only precise detection but also a systematic approach with remote notification and automated response capabilities. The inclusion of 4G IoT technology breaks down spatial limitations, ensuring safety is always with you. This product is your reliable partner in protecting your home and preventing gas accidents.

Frequently Asked Questions

What makes the JT-CA319N different from traditional gas alarms?

Traditional alarms only sound an alarm on-site but lack automated response and remote notification. The JT-CA319N+DN15 system not only triggers local alarms but also sends instant mobile alerts via 4G, shuts off the gas valve automatically, and turns on the ventilation system to actively resolve the danger.

Does the 4G remote monitoring require home Wi-Fi?

No, it features a built-in 4G IoT module. It operates independently of your home Wi-Fi network, providing stable and uninterrupted coverage for remote monitoring and mobile alerts.

How does the dual safety linkage protection work?

When a methane leak is detected, the system immediately cuts off the gas supply at the source by shutting down the solenoid valve. At the same time, it activates an linked exhaust fan to clear any accumulated gas in the room.

How quickly does the system detect a gas leak?

The device uses a high-performance semiconductor sensor optimized for methane, delivering a rapid response time of less than 20 seconds to ensure quick hazard detection.

Is the detector durable enough for kitchen environments?

Yes, it is built with durable ABS material and features anti-static, anti-oil fume, and anti-alcohol designs. This industrial-grade protection helps prevent false alarms caused by typical kitchen conditions.
