KERUI W181 GSM/WiFi Alarm System User Manual

1. Introduction

The KERUI W181 is a high-end GSM/WIFI (2.4G) alarm system designed for robust home security. It features a 1.7-inch TFT color screen, a touch keyboard, and a powerful CPU for stable and reliable performance. The system supports wireless connection with various sensors and accessories, including PIR motion detectors, door/window contacts, smoke detectors, gas detectors, remote controls, and emergency buttons.

When an alarm is triggered, the host panel displays the alarm zone, activates an 80 dB siren (up to 110 dB with an external horn), sends alarm messages via GSM, and calls preset numbers. WiFi connectivity allows for alarm notifications to be pushed to your smartphone via the Tuya Smart app. This system is ideal for securing homes, factories, schools, shops, and other properties.

Key Features:

• Colorful TFT color display with humanized menu and voice prompts.
• Supports 99 zones and 8 zone types, with ON/OFF siren control per zone.
• 8 groups of timing Arm/Disarm functions for automated control.

• Low power reminder and anti-tamper function.
• Built-in rechargeable high-capacity lithium battery for standby power during outages.
• SMS and calling reminders upon power-off.
• Panel host supports 850/900/1800/1900MHz GSM / GPRS module.

2. Setup

2.1 Installation Location

Install the main panel in a central location within the guarded area to ensure it receives signals from all detectors. Avoid large metal objects, appliances with high-frequency interference, reinforced concrete walls, and fire doors, as these can obstruct signals.

2.2 Initial Power-on

1. Insert the SIM card into the card slot on the host panel.
2. Connect the host to power.
3. Long press the [ON/OFF] button. The host will voice prompt "Welcome to smart voice alarm".
4. The host will begin self-testing the GSM network. The "GSM signal LED" will flash (once per second) while searching for a signal.
5. Once the network is working properly, the SIM Card icon will disappear, indicating normal GSM and SIM card operation. If the LED continues to flash, there may be an issue with the SIM card or network detection.

2.3 WIFI Configuration (Tuya Smart App)

The KERUI W181 system integrates with the Tuya Smart app for remote control and notifications. Download the "TUYA SMART" app from your App Store or Android mobile phone market.

Intelligent Connection:

1. Ensure your home WiFi router is connected to the external network.
2. Open the Tuya Smart app, go to the "all devices" page, and click the "add device" icon.
3. Select "WiFi connector" from the list.
4. Enter your 2.4 GHz WiFi network name and password. (Note: The system only supports 2.4 GHz WiFi, not 5.0 GHz).
5. Click "confirm" to start the configuration process.

AP Connection (Compatibility Mode):

1. Ensure the alarm system is not in "alarm" or "low power" state.
2. In the Tuya Smart app, go to "all devices", click "add device", and select "WiFi connector".
3. On the "add device" page, click "hot distribution network (compatibility mode)" in the upper right corner to enter the AP configuration page.
4. The app will guide you to the WiFi connection configuration page of your mobile phone.
5. On the alarm host, press the menu key to enter the main page, then use the [UP/DOWN] key to move the cursor to [LAN], and press [OK] or number [7] to enter the LAN page.
6. Press number [3] to enter the AP network configuration state. The WiFi module of the host will start to distribute a WiFi hotspot (e.g., "smarlife-xxxx", no password).
7. Connect your mobile phone to this hotspot.
8. Return to the app operation page and enter the AP connection page to complete the setup.

2.4 Adding Remote Controls

1. On the host panel, navigate to the "Add Accessories" menu.
2. Select "Add Remote Control" (option 1).
3. Enter the desired remote control number (01-02).
4. Press any key on the remote control. The host will confirm successful addition.

2.5 Adding Detectors (PIR/Door Sensor)

1. On the host panel, navigate to the "Add Accessories" menu.
2. Select "Add Detector" (option 2).
3. Enter the desired zone number (01-99).
4. Trigger the detector (e.g., open a door with a door sensor, or move in front of a PIR sensor). The host will voice prompt "Add Successfully".
5. If the voice prompt repeats, the detector has already been added. The host can learn up to 150 different detectors.

2.6 Installation of Door Sensor

The door sensor consists of two parts: a transmitter and a magnet. It detects the opening and closing state of doors, windows, or any openable object.

1. Clean the installation surface.
2. Attach the wireless door sensor using the double-sided adhesive tape provided.
3. Install part A (transmitter) on the fixed part of the door/window frame and part B (magnet) on the movable part of the door/window.
4. Ensure A and B are in the same vertical line and the distance between them is no greater than 1 cm when closed.
5. After installation, the indicator light on the sensor will flash for 1 second when the door opens, confirming successful installation.
6. A constant light on the indicator suggests low power.
7. For added security, both parts can be reinforced with screws.

2.7 Installation of PIR Motion Detector

PIR motion detectors are designed to detect movement within their coverage area.

1. Ensure the power switch of the PIR motion sensor is ON.
2. Install the detector at approximately 2.2 meters above the ground in a room corner for optimal detection range.
3. It should form a 90-degree angle with the walking line for best detection.
4. Take out the supplied bracket and insert it into the slot.
5. Fix the pedestal to the wall with two screws.
6. Press the PIR sensor with its bracket into the center hole of the pedestal and adjust the angle.

Important Considerations:

• The detector should not face directly towards windows.
• Ensure no large objects obstruct the detection coverage.
• Avoid placing two infrared detectors in the same space to prevent interference.
• Keep away from windows, heating/cooling machines, stoves, or other appliances that cause rapid temperature changes, which can lead to false alarms.
• PIR motion detectors are for indoor use only.

2.8 Code Match: Host & Wireless Strobe Siren

1. In standby mode, long press the SET key on the strobe siren until its alarm indicator lights constantly (learning state).
2. On the host's intelligent accessories page, input '0'.
3. Press the [ARM] or [DISARM] key on the host. The host will send a signal.
4. The wireless strobe siren will beep twice and its indicator will flash twice, confirming successful code match.
5. Press the SET key on the strobe siren to exit the learning state.
6. To check: Press [ARM] or [DISARM] on the host to switch the siren ON/OFF. If OFF, the siren beeps "di di"; if ON, the siren alarms.

2.9 Code Match: Host & Smart Socket

1. In standby mode, long press the SET key on the smart socket for 5 seconds until its indicator light turns off (learning state).
2. On the host's intelligent accessories page, input '0'.
3. Press the [ARM] or [DISARM] key on the host. The host will send a signal.
4. The smart socket indicator light will flash twice, confirming successful code match.
5. Press the SET key on the smart socket to exit the learning state.
6. To check: Press [ARM] or [DISARM] on the host to switch the smart socket ON/OFF. If OFF, the socket lights RED; if ON, it lights BLUE.
