If the device is already mounted, you will need to remove it and pair it at a safe level.   | ![warning-ORANGE-png](https://info.wondrwall.co.uk/hs-fs/hubfs/warning-ORANGE-png.png?width=34&height=34&name=warning-ORANGE-png.png) | **Warning:** Do not attempt to pair the device while on a ladder. | | --- | --- | #### Step-by-Step Guide 1. Ensure your phone or tablet is logged into the Wondrwall app and your system is online. 2. Navigate to the **Devices** page using the menu, then press the **+** icon to open the device addition page. Select ‘Siren’ from the device selection list. 3. Once you’ve selected **Siren**, remove the cover of the siren using a screwdriver. Press **Next** on the app. 4. Ensure the device is powered on using the on/off switch located on the main circuit board to the left. 5. Press and hold the function button for about 10 seconds until the **right-side LED flashes**. The function button is labelled **Learn** and is located just under the on/off button. Release the button. Press **Next** on the app, the device will now pair. 6. After configuration, press the displayed location name to show a list of existing locations (scroll down if necessary). Press the one you require to select it. Alternatively, press **Create new location** to specify a new location. Press **Next** when you are happy with the selected location. 7. Finally, either press **Finish** on the success screen to end the installation (or **Add another device** to continue pairing other devices). 8. Replace the cover and use the screw to fix it in place. 9. Attach the siren to the outside of the house, high up and in a location where it can be seen. The Siren should now be visible in the Security widget in your Wondrwall app.  #### How to arm and disarm the Siren. Now that the Siren is visible in the Security widget, a slider is available for use. **Armed:** The Siren will start sounding when it detects either a panic situation or if someone tries to tamper with it. **Disarmed:** The Siren has been disarmed and will not activate under any circumstances. --- *If you have any issues which cannot be solved using our Support Hub, please don't hesitate to contact the Wondrwall Support Team for further assistance.* ---   - [Getting Started](https://info.wondrwall.co.uk/support/getting-started?hsLang=en#main-content) - [First Questions](https://info.wondrwall.co.uk/support/getting-started?hsLang=en#first-questions) - [Login & Home Management](https://info.wondrwall.co.uk/support/getting-started?hsLang=en#login-home-management) - [Home Initialisation](https://info.wondrwall.co.uk/support/getting-started?hsLang=en#home-initialisation) - [Lighting](https://info.wondrwall.co.uk/support/lighting?hsLang=en#main-content) - [Configuring Lighting](https://info.wondrwall.co.uk/support/lighting?hsLang=en#configuring-lighting) - [Lighting Controls & Features](https://info.wondrwall.co.uk/support/lighting?hsLang=en#lighting-controls-features) - [Troubleshooting](https://info.wondrwall.co.uk/support/lighting?hsLang=en#troubleshooting) - [Wi-Fi](https://info.wondrwall.co.uk/support/lighting?hsLang=en#wi-fi) - [Heating](https://info.wondrwall.co.uk/support/heating?hsLang=en#main-content) - [General](https://info.wondrwall.co.uk/support/heating?hsLang=en#general) - [About Wondrwall Heating Devices](https://info.wondrwall.co.uk/support/heating?hsLang=en#about-wondrwall-heating-devices) - [Schedules & Heating Efficiently](https://info.wondrwall.co.uk/support/heating?hsLang=en#schedules-heating-efficiently) - [Troubleshooting](https://info.wondrwall.co.uk/support/heating?hsLang=en#troubleshooting) - [Thermostat](https://info.wondrwall.co.uk/support/heating?hsLang=en#thermostat) - [Energy](https://info.wondrwall.co.uk/support/energy?hsLang=en#main-content) - [Configuring Inverters & Batteries](https://info.wondrwall.co.uk/support/energy?hsLang=en#configuring-inverters-batteries) - [Scheduling & Tariffs](https://info.wondrwall.co.uk/support/energy?hsLang=en#scheduling-tariffs) - [Troubleshooting](https://info.wondrwall.co.uk/support/energy?hsLang=en#troubleshooting) - [Solar PV](https://info.wondrwall.co.uk/support/energy?hsLang=en#solar-pv) - [Security](https://info.wondrwall.co.uk/support/security?hsLang=en#main-content) - [Arming & Disarming](https://info.wondrwall.co.uk/support/security?hsLang=en#arming-disarming) - [Security Devices](https://info.wondrwall.co.uk/support/security?hsLang=en#security-devices) - [EV Charging](https://info.wondrwall.co.uk/support/ev-charging?hsLang=en#main-content) - [Configuring & Scheduling](https://info.wondrwall.co.uk/support/ev-charging?hsLang=en#configuring-scheduling) - [Hot Water](https://info.wondrwall.co.uk/support/hot-water?hsLang=en#main-content) - [Mixergy](https://info.wondrwall.co.uk/support/hot-water?hsLang=en#mixergy) - [Entertainment](https://info.wondrwall.co.uk/support/entertainment?hsLang=en#main-content) - [Sonos](https://info.wondrwall.co.uk/support/entertainment?hsLang=en#sonos) - [Installation](https://info.wondrwall.co.uk/support/installation?hsLang=en#main-content) - [Light Switch](https://info.wondrwall.co.uk/support/installation?hsLang=en#light-switch) - [Thermostat](https://info.wondrwall.co.uk/support/installation?hsLang=en#thermostat) - [In-Home Display](https://info.wondrwall.co.uk/support/installation?hsLang=en#in-home-display) - [Siren](https://info.wondrwall.co.uk/support/installation?hsLang=en#siren) - [Smart Relay](https://info.wondrwall.co.uk/support/installation?hsLang=en#smart-relay) [![Chill listening crop-3](https://info.wondrwall.co.uk/hs-fs/hubfs/WW_Marque.png?width=50&height=32&name=WW_Marque.png "Chill listening crop-3")](https://info.wondrwall.co.uk/support?hsLang=en) Wondrwall Support Hub Copyright © 2026, Wondrwall Group
