KERUI D025 Wireless Window Door Magnet Sensor Instruction Manual

1. Product Overview

The KERUI D025 Wireless Window Door Magnet Sensor is designed to enhance the security of your home or business. This sensor works by detecting when a door or window is opened, sending an immediate alert to your compatible KERUI 433MHz alarm system (such as W202 or W181 models). It provides reliable 24/7 monitoring, ensuring you are promptly notified of any unauthorized access.

2. Setup Instructions

2.1 Pre-configuration for Network Connection (TuyaSmart App)

1. Ensure your smartphone is connected to a 2.4GHz Wi-Fi network.
2. Activate the Bluetooth function on your smartphone.
3. Open the Location Services in your phone's "Privacy" settings, and grant authorization to the TuyaSmart APP. You can choose "While Using the App" or "Always".

2.2 Connecting to TuyaSmart App (Bluetooth Method 1)

This method is for connecting the main alarm hub to the TuyaSmart app. The sensor will then be added as an accessory to the hub.

1. Open the TuyaSmart App on your smartphone.
2. Tap the "Add Device" button. The app will begin searching for nearby devices.
3. Select "WIFI loudspeakers" (this represents the KERUI alarm hub) from the discovered devices.
4. Enter your 2.4GHz Wi-Fi network's SSID (name) and password.
5. Tap "Next". The alarm hub will connect to the network and be added to your app.
6. Tap "Done" once the device is successfully added.

2.3 Adding Accessories (Method 1 - via App)

After connecting your alarm hub, you can add the D025 sensor as an accessory.

1. In the TuyaSmart App, navigate to the control panel of your connected alarm hub.
2. Tap on "Accessories".
3. Tap the "+" icon (or similar add button) to initiate the accessory adding process.
4. Trigger the D025 sensor by separating its two magnetic parts (e.g., open the door/window it's installed on). If adding a remote, press any button on the remote.
5. Confirm successful addition in the app.

2.4 Setting the Detector's Zone Mode

Each detector can be assigned a specific zone mode to define its behavior under different alarm system states.

1. Access "Accessory setting" for the detector in the TuyaSmart app.
2. You can name your accessory (e.g., "Front Door", "Living Room Window") for easy identification.
3. Select the desired "Zone mode" from the available options.
4. Select the "Type" (e.g., "Door contact").
5. Save the settings.

Detector Zone Mode Table:

Note: "X" means the WiFi Alarm Hub will not trigger, "O" means the WiFi Alarm Hub will trigger.

3. Operating Instructions

Once the KERUI D025 sensor is paired with your alarm system and configured with the desired zone mode, it will monitor the opening and closing of the protected door or window. When triggered, the sensor sends a signal to the alarm hub, which then activates the alarm and sends notifications (SMS/calls) to your pre-set phone numbers.

The alarm system can be set to different arming modes (Disarm, Away Arm, Home Arm) via the TuyaSmart app or a remote control. The sensor's behavior (whether it triggers an alarm) depends on its assigned zone mode and the current arming state of the hub, as detailed in the 'Detector Zone Mode' table in the Setup section.

4. Maintenance

The KERUI D025 sensor is powered by a CR2032 battery. When the battery level is low, the sensor may indicate this (e.g., via an LED indicator or app notification, if supported by the alarm system). To replace the battery:

1. Carefully open the sensor casing.
2. Remove the old CR2032 battery.
3. Insert a new CR2032 battery, ensuring correct polarity.
4. Close the sensor casing securely.

5. Troubleshooting

5.1 Common Issues and Solutions

• Q: How to restart the sensor?
  A: To restart the sensor, you typically need to remove and reinsert its CR2032 battery. This performs a hard reset. If the issue persists, check the connection with your alarm hub via the TuyaSmart app.
• Q: Sensor not triggering alarm.
  A: Check the battery level of the sensor. Ensure the sensor and magnet are correctly aligned and within the specified gap. Verify the sensor's zone mode settings in the TuyaSmart app (refer to the 'Detector Zone Mode' table in Section 2.4). Ensure the alarm hub is armed in a mode that allows the sensor to trigger (e.g., Away Arm or Home Arm, depending on the zone mode).
• Q: Sensor not pairing with the alarm hub.
  A: Ensure your phone is connected to 2.4GHz Wi-Fi, Bluetooth is enabled, and Location Services are authorized for the TuyaSmart app. Make sure the alarm hub is in pairing mode. Try resetting the sensor by removing and reinserting the battery, then attempt pairing again.
