The YoLink X3 Outdoor Alarm Controller is a smart device that allows you to control a 12VDC siren horn or any other 12VDC, maximum 400mA (resistive) alarm devices remotely using the YoLink app on your smartphone or tablet or by pressing the SET button on the device.

The differences between the four alarms are as follows:

1. Siren Alarm, Indoor Siren YS7103: This alarm is AC/DC powered, with batteries serving as backup. The standby backup battery life is approximately 80 hours.

2. Smart Outdoor Relay & Alarm Controlle YS7104: This alarm is battery-powered, offering a standby battery life of about 1.5 years. It has an output of about 4-5 watts.

3. X3 Commercial Grade Smart Outdoor Alarm Controller YS7105: This alarm is battery-powered and provides an extended standby battery life of about 10 years.

4. Outdoor Alarm Controller 2 YS7107: This alarm can be powered by either batteries or an AC power adapter. When powered by batteries, it has a standby battery life of about 5 years. It has an output of about 12 watts, allowing it to connect to a strobe light.

Yes, the YoLink Hub serves as the central controller for YoLink devices, connecting the YoLink Alarm Controller to the internet and cloud. Once the devices are connected to the internet, you can activate or deactivate the alarms for the Alarm Controller through the YoLink App. Please note that the YoLink Hub requires a 2.4 GHz Wi-Fi connection or a wired connection to function properly.

The YoLink Alarm Controller 2 and Siren will automatically silence the alarm based on the Alarm Duration setting in the YoLink app, with the default setting being 30 seconds.

There are other ways to silence the Alarm as well:

1. Press the SET button on the Alarm Controller.

2. Tap the Stop Alarm button in the YoLink app.

3. Temporarily mute the controller in the YoLink app (requires contacting YoLink customer support to update the firmware, and setting the mute durations in the details screen).

4. Press the associated OFF button on the optional YoLink Remote (sold separately).

5. Press the associated Stop Alarm or Mute button on the optional YoLink SirenFob (sold separately).

The siren horns provided for use with the YoLink Alarm Controller has a sound intensity of 110dB or 140dB.

 Unfortunately, the siren horn provided for use with the YoLink Alarm Controller has a fixed sound intensity of 110dB or 140dB and cannot be adjusted. If you require adjustable volume, consider using the YS7103 Siren or YS1604 SpeakerHub.

Once you have connected the YoLink Alarm Controller 2 to Alexa or Google via the YoLink Hub, you can use voice commands through Alexa or Google Assistant to turn the Alarm Controller 2 on or off as needed. Please note that the YoLink Hub is required for this functionality.

To enable the mute functionality for the YoLink Alarm, please contact YoLink customer support to request a firmware update. Once the firmware has been updated, you will be able to mute the alarm using the YoLink app.

 Yes, the YoLink Alarm Controller X3 is compatible with IFTTT, which allows you to create custom applets for starting or stopping the Siren Alarm. By integrating IFTTT, you can further personalize and automate your smart home system, tailoring it to your specific needs and preferences.

The minimum alarm duration for the YoLink Siren Alarm can be set to 1 second. To configure this setting, go to the device detail screen in the YoLink app. Please ensure that both the firmware and the app are up to date for the best experience.

Follow these steps in the YoLink app:

1. Open the YoLink app and go to Menu > Settings.

2. Select "Alarm Strategies."

3. Find an existing strategy or create a new one.

4. In the "Related Device" section, select your door sensors.

5. In the "Trigger Action" section, select the YoLink Siren.

By following these steps, you'll successfully link your siren with the door sensors.

The YoLink app does not send notifications when the alarm is triggered. However, the app will update the status of the siren alarm, and you can check the alarm's history within the app to stay informed about its activity.

Yes, you can set up different alarm durations by creating customized scenes in the YoLink app. First, set the alarm duration to the longest desired duration (e.g., 5 minutes) in the siren details screen. Then, create new scenes for shorter durations:

1. For a 1-second alarm scene: Add a device action - Siren - Start Alarm, set a delay of 1 second, and then add another device action - Siren - Stop Alarm.

2. For a 1-minute alarm scene: Add a device action - Siren - Start Alarm, set a delay of 1 minute, and then add another device action - Siren - Stop Alarm.

These customized scenes allow you to use different alarm durations depending on your preferences and needs.

 The YoLink Alarm Controller 2 is a Class D device with a heartbeat signal time of 4 hours. This means it sends a signal to the hub every 4 hours to maintain communication. On the other hand, water leak sensors are Class A devices with a heartbeat signal time of 4 hours.

When Hub A is offline, the device will automatically connect to Hub B upon detecting a status change (e.g., from normal to water detected), when the SET button is pushed, or when the heartbeat signal is sent. For water leak sensors, if the sensor detects water, it will connect to Hub B and send alerts. However, for the YS7107 alarm controller, if you don't push the SET button, it will take up to 4 hours for the device to connect to Hub B.

Yes, you can install multiple hubs at different locations on your property. After installation, if all sirens show as online, you can program a Flex Fob or create a scene in the app to trigger all sirens simultaneously. Three or four hubs should be sufficient to cover your 15,000 square feet property and allow you to trigger all sirens in the strategy.

There are three ways to link YoLink sensors with the YoLink Siren:

1. YoLink App - Smart Automation: You can create a smart automation rule, such as IF "YoLink Water Leak Sensor - Water Leak Alert," THEN "YoLink Sirens - Start Alarm." This function requires the Hub and an internet connection. For multiple sensors, you need to create multiple automation rules.

2. YoLink App - Alarm Strategy: You can set an "Alarm Strategy" for your sensors to trigger the siren alarms. If you have multiple sensors, you can create different alarm strategies for each sensor type, such as water leak sensors, door sensors, and motion sensors. After creating the alarm strategies, you can add smart scenes "Home" or "Away" to enable or disable the alarm strategy based on your location. When you are out of home, click the "Away" scene to arm; and when you are at home, click the "Home" scene to disarm the alarm strategy for motion sensors or door sensors. You can also add the scenes to "Favorite" for quick access.

3. YoLink Control: This method works even without the Hub and internet connection. With YoLink Control, the sensor will trigger the siren all the time, and you need to pair them one by one. If you want to mute the siren temporarily, you may need a SirenFob to pair YoLink Control between the SirenFob and Siren to mute it. 

With YoLink Control, there is no strict limit to the number of Controllers you can pair with the Alarm Controller. However, for optimal performance, we recommend linking up to 128 devices.

 Yes, you can pair the motion sensor with the siren so that when the motion is detected, the siren will be triggered. To arm or disarm the system, pair the siren with a SirenFob. Mute the siren to disarm the system and unmute it to arm the system. This setup will work without an internet connection. However, before configuring this setup, please contact YoLink customer support to update the firmware. A YoLink Hub(internet) is required for firmware updates and to set mute durations.

There are two possible reasons:

Incomplete device status loading due to poor mobile phone network connectivity. Ensure that your mobile phone has a strong and stable network connection for optimal performance.

Insufficient interval time between device operations. If the device is operated too quickly or repeatedly, it may not fully respond, leading to connectivity issues. Ensure that the interval time between operations is more than 6 seconds to avoid this problem.

Yes, you can create custom schedules for the YoLink Siren within the YoLink app. This allows you to automatically activate or silence the alarm at specific times and days.

Please note that turning off the alarm strategy or automation for the sensor in the YoLink app doesn't deactivate the D2D pairing.

To fix this issue, follow these steps to perform a factory reset for the siren controller:

1. Hold down the SET button for 20-23 seconds until the status light alternates between red and green blinking.

2. Release the button (if held for longer than 23 seconds, it will cancel the factory reset).

3. The factory reset is complete when the status light stops blinking.

Once the factory reset is done, attempt to pair the sensor with the siren controller again.

To achieve the desired behaviors for your HOME and AWAY settings, follow these steps:

1. Go to the siren details screen in the YoLink app and set the alarm duration to 5 minutes.

2. Create two scenes:

a. 1-second siren scene: add behavior - add siren - start alarm; add behavior - delay 1 second; add behavior - add siren - stop alarm.

b. 1-minute siren scene: add behavior - add siren - start alarm; add behavior - delay 1 minute; add behavior - add siren - stop alarm.

3. Set up three scenes:

a. Away scene: add behavior - add alarm strategy - choose a strategy related to your sensors - choose advanced settings - trigger siren - save.

b. Arm-Stay scene: add behavior - add alarm strategy - choose a strategy related to your sensors - choose advanced settings - trigger "1-minute siren scene" - save.

c. Disarmed scene: add behavior - add alarm strategy - choose a strategy related to your sensors - choose advanced settings - trigger "1-second siren scene" - save.

By setting up these scenes, you can customize your siren alarm behaviors for different situations, such as being at home or away.
