OPERATING MANUAL

description

The ZigBee Wireless E9Z household combustible gas detector (detector) adopts high quality gas sensor. It is made with high performance MCU and advanced electronic elements as well as sophisticated technologies. Its software and hardware technology enables it to simultaneously monitor sensor failure while detecting gas leakage concentration, with high safety and reliability. This detector is suitable for installing in residential houses with potential gas leakage, it can consecutively monitor indoor combustible gas concentration, when the gas concentration reaches its alarming value, the detector will send out sound and light alarm. It will help you to take immediate action to prevent fire, blast and poisoning accidents from happening. 

• Single-source detection, protected against false alarms due to dust, insects or moisture.
• Professional labyrinth design, rapid fire detection.
• Notification function via app, check battery level and working status at any time.
• Housing made of fire-resistant plastic with a glossy surface.

NOTE:  You will need a Nous E1, Nous E7 or other Tuya-compatible ZigBee gateway/hub to connect.

How to connect a smart socket to a Zigbee network:

1	Connect your smartphone to the access point that will be used to connect your smart device. Make sure the network frequency range is 2.4 GHz, otherwise the device will not connect as Zigbee Hubs are not designed to work with 5 GHz Wi-Fi networks; (your ZigBee Hub must already be connected to the app)
2	Turn on the device. If the light indicator does not flash quickly, press the button for 5-7 seconds to reset the device settings to factory defaults.
3	Open the Nous Smart Home app and click the add new device button
4	An auto-scan will appear, prompting you to add a new device. Confirm the connection and start pairing.
5	If auto-scan doesn't see your device, you can select it manually from the device list
6	In the "Add Manually" tab, select the "Smart Sensors" category, and in it the "E9 Gas Detector" model, as shown in the figure above;
7	In the window that opens, select "next step" and click the "Forward" button;
8	connecting to a Zigbee hub
8	A window will appear indicating the degree of network connection and adding the current user of the application to the list of devices:
9	Once the procedure is complete, a window will appear where you can name the device and select the room it is in. The device name will also be used by Amazon Alexa and Google Home.
When the device is removed from the user's device list in the application,  the smart  socket settings are reset to factory settings and you will need to go through the Wi-Fi connection procedure again. If the password for the Wi-Fi access point was entered incorrectly, the application will display a "Failed to connect to Wi-Fi" window after the timer expires, offering step-by-step steps to fix the problem.

Wiring Diagram

1	The power supply cable is with a plug, please directly connect to a correct socket.
2	The solenoid valve has polarity, and the red positive and black negative lines must be connected one by one when connecting.
3	The relay has no polarity and does not need to distinguish between positive and negative terminals when connected, and can be directly connected.
4	If the product contains the function of solenoid valve and relay, add. If not, omit.

Installation method

Installation procedure using the mounting plate:
1	This detector is only suitable for indoor environment. Please install it where there is potential gas leakage or accumulation. and it should be installed horizontally 1m~4m from the gas appliance and vertically 0.3m~1m from the ceiling. Users could choose install the detector according to below diagram based on actual situation.
2	Choose a place on the wall suitable for installing the detector;
3	Use expansion screws to fix the installation baseplate;
4	Power on the detector and check to ensure it works normally;
5	Install the detector by hanging it onto the baseplate.
	Importantly:	Make sure that the Zigbee network in the selected installation location is stable and has a sufficient level.
