PNI Wi-Fi Smart Safe House Kit 300, gas sensor and solenoid valve 3/4"

Product detailed description

This gas detection and shut-off system is suitable for installation in residential, commercial, and industrial properties where natural gas, liquefied petroleum gas (LPG), and other hydrocarbon gases are in use. It is commonly used in kitchens, boiler rooms, and utility areas where gas appliances are located. The system is designed for integration with existing gas supply lines and is ideal for installers working on safety systems for heating, plumbing, and ventilation applications.

The system is designed for use in environments where gas leaks could pose a risk to safety. It is particularly useful in properties where remote monitoring is required, such as in multi-family dwellings, service buildings, or properties managed by remote maintenance teams. The Wi-Fi connectivity allows for real-time monitoring and alerts, making it a valuable addition to smart home and building automation systems.

The system operates on a wide voltage range of 110–240 V AC and consumes less than 3 W of power. The gas sensor is capable of detecting a range of hydrocarbon gases, including methane, propane, butane, ethane, and LPG. The alarm is triggered at 7% of the lower explosive limit (LEL), ensuring early detection of potentially dangerous gas concentrations. The solenoid valve is controlled via an electrical impulse, allowing for rapid shut-off of the gas supply when a leak is detected.Installation and connection The installation process involves mounting the gas sensor in a suitable location, typically near potential gas sources such as gas stoves, boilers, or storage tanks. The solenoid valve is connected to the gas supply line using a 3/4 inch connection. The sensor and valve are linked via a pre-wired cable, and the system is connected to the mains power supply. The Wi-Fi module must be configured to connect to the local network, and the device must be added to the Tuya Smart app for remote monitoring. Key installation considerations include ensuring the sensor is placed in a location with good air circulation and away from direct sources of heat or moisture. The solenoid valve must be installed in a position that allows for manual override in case of system failure. Common installation mistakes include incorrect positioning of the sensor, failure to secure the cables properly, and incorrect configuration of the Wi-Fi settings.

Compatibility and accessories

The system is compatible with the Tuya Smart app, allowing for integration with other smart devices and automation systems. It is designed to work with standard gas supply lines and is suitable for use with a wide range of gas appliances. No additional accessories are required for basic operation, as the system includes all necessary components. However, installers should ensure that the gas supply line is compatible with the solenoid valve’s 3/4 inch connection.

Technical background for designers

The gas sensor uses a catalytic bead sensor to detect combustible gases. When a gas is present, it reacts with the sensor, causing a change in resistance that is detected by the system. The solenoid valve is an electromechanical device that opens and closes in response to an electrical signal. The system is designed to provide a rapid response to gas leaks, with the alarm triggering at 7% LEL and the valve closing within seconds of detection. The system is constructed using durable materials suitable for indoor environments. The housing is designed to protect the internal components from dust and moisture. The system is intended for use in environments with temperatures ranging from -10°C to +50°C. The Wi-Fi module operates on the 2.4 GHz frequency band and requires a stable internet connection for remote monitoring.

Service and operation

The system requires minimal maintenance, with no scheduled service intervals specified. Regular checks should be performed to ensure that the sensor is functioning correctly and that the solenoid valve is operating as expected. The system includes a test function that can be used to verify the alarm and shut-off functions. In the event of a system failure, the solenoid valve can be manually overridden by pulling the red button to restore gas flow. Installers should ensure that the system is regularly tested and that the alarm is not ignored when triggered. The system should be reconnected to the gas supply only after the cause of the alarm has been identified and resolved. The Tuya Smart app can be used to monitor the system remotely and to receive notifications in the event of an alarm.

Frequently asked questions

Can the gas sensor be connected to a third-party smart home system?
Integration with third-party systems is not supported. The system is designed to work exclusively with the Tuya Smart app.

Is the solenoid valve compatible with all types of gas supply lines?
The solenoid valve is compatible with standard gas supply lines that have a 3/4 inch connection. It is not suitable for use with non-standard or high-pressure gas lines.

Can the alarm be silenced remotely?
The alarm cannot be silenced remotely. To stop the alarm, the sensor must be disconnected from the power supply or the gas concentration must drop below the alarm threshold.

How long does the system remain active after a power outage?
The system requires continuous power to operate. In the event of a power outage, the system will not function until power is restored.
