<div><span></span>### **Overview**

<div><div>The Alarm.com Flex IO® sensor enables new levels of flexibility for monitoring valuable property and assets anywhere that LTE connectivity is available. Whether used with a backyard gate or a remote storage unit, the Alarm.com Flex IO® sensor empowers users to keep an eye on what matters most. It can be used with the included magnet to monitor doors, gates, and other entryways.

**Important**: The Alarm.com Flex IO® sensor is an awareness device that is not intended for life safety use cases.

The following are some example applications:

- Shed Doors
- Storage Units
- Chicken Coop
- Fences
- Delivery Boxes
- RV Doors

<div>The device serial number is printed inside the battery compartment as shown in the following image.

<div><figure class="gosafer-step-image" style="margin: 1em 0 1.25em; padding: 0.75em; text-align: center; background: #fafafa; border: 1px solid #d9e0e5; border-radius: 6px;">![Flex IMEI location](https://answers.alarm.com/@api/deki/files/22337/Flex_IMEI_location.PNG?revision=1)<figcaption style="margin-top: 0.55em; color: #555; font-size: 0.92em;">Flex IMEI location</figcaption></figure></div></div></div></div><div><div><span></span>### **Insert the batteries**<span style="display: inline-block; padding: 0.05em 0.4em; margin: 0 0.1em; background: #eef4f7; border: 1px solid #c9d7df; border-radius: 3px; font-weight: 600;">Icn Chevron Up</span> 

<div><div><div>1. Remove the front card.
2. Install the included batteries.
3. Close the battery compartment door, and tighten the screw securely. 
    - Make sure the battery door screw is securely tightened to clear the battery door tamper. This will also ensure a waterproof seal.
    - If this screw is not fully tightened, the LED will show a single red blink every 2 seconds. <div class="gosafer-note" style="margin: 1em 0; padding: 0.85em 1em; border-left: 4px solid #3978a8; background: #eef7fc;">**Caution**: Be careful to not over-torque the screw. Power tools should be avoided.</div>

**Note**: Throughout the installation process the LED will start blinking at multiple intervals. This is normal.

<div><div><div>To check for device signal:

1. Bring the sensor to the location you would like to install it.
2. Press the tamper button to check the signal. This tamper button must be fully pressed (until you hear a clicking sound).
3. The install wizard will look for the device signal. 
    - A *Success* message should appear if successful.
    - If unable to get a signal from your device, try again. If you continue to experience issues, contact <flexsupport@alarm.com> for additional support.

</div><div><figure class="gosafer-step-image" style="margin: 1em 0 1.25em; padding: 0.75em; text-align: center; background: #fafafa; border: 1px solid #d9e0e5; border-radius: 6px;">![Flex IO tamper](https://answers.alarm.com/@api/deki/files/22202/Flex_IO_tamper.PNG?revision=1)<figcaption style="margin-top: 0.55em; color: #555; font-size: 0.92em;">Flex IO tamper</figcaption></figure></div></div></div></div></div><div><div><span></span>### **Select magnet position**<span style="display: inline-block; padding: 0.05em 0.4em; margin: 0 0.1em; background: #eef4f7; border: 1px solid #c9d7df; border-radius: 3px; font-weight: 600;">Icn Chevron Up</span> 

<div>Like a standard door/window contact, the Alarm.com Flex IO® sensor can be installed with the accompanying magnet to detect activity at potential entryways.

To determine your installation orientation, consider the following:

- Three separate magnet positions are available. Only one magnet position can be active at a time.
- Use the tick marks on the sides of the device for guidance: 
    - | = *Position 1*
    - || = *Position 2*
    - ||| = *Position 3*
- The magnet should be positioned no more than 1.25 inches from the device.

<div><figure class="gosafer-step-image" style="margin: 1em 0 1.25em; padding: 0.75em; text-align: center; background: #fafafa; border: 1px solid #d9e0e5; border-radius: 6px;">![Flex magnet positions](https://answers.alarm.com/@api/deki/files/22339/Flex_magnet_positions.png?revision=1)<figcaption style="margin-top: 0.55em; color: #555; font-size: 0.92em;">Flex magnet positions</figcaption></figure></div>In the following example photo, *Position 1* would be selected since the magnet is to the left of the sensor.

If Position 2 or 3 were selected, the sensor would not accurately report when the door opens/closes.

<div><figure class="gosafer-step-image" style="margin: 1em 0 1.25em; padding: 0.75em; text-align: center; background: #fafafa; border: 1px solid #d9e0e5; border-radius: 6px;">![Flex IO example](https://answers.alarm.com/@api/deki/files/22288/Flex_IO_example.PNG?revision=1)<figcaption style="margin-top: 0.55em; color: #555; font-size: 0.92em;">Flex IO example</figcaption></figure></div></div></div></div><div><div><span></span>### **Mounting options and installation**<span style="display: inline-block; padding: 0.05em 0.4em; margin: 0 0.1em; background: #eef4f7; border: 1px solid #c9d7df; border-radius: 3px; font-weight: 600;">Icn Chevron Up</span> 

<div>The Alarm.com Flex IO® sensor can be mounted using either screws or zip ties.

**Important**: A mounting tamper is located on the back of the Alarm.com Flex IO® sensor. This tamper button must be fully pressed (until you hear a clicking sound) to avoid reporting a mounting tamper malfunction.

<div><span></span>### **If using screws:** 

<div><div>1. Remove batteries to avoid damage to the batteries. Screw mounting holes are located in the battery compartment.
2. Use two #8 Phillips screws to puncture the gasket and securely mount the Alarm.com Flex IO® sensor.
3. Take care not to over-torque the screws. Power tools should be avoided. If pilot holes are necessary, a drill bit size of 5/64’’ is recommended.
4. Once mounted, insert the batteries and close the battery door.

<div><div>1. The batteries and battery cover can remain installed.
2. Use the zip tie grooves at the top and bottom of the Alarm.com Flex IO® sensor to ensure a secure installation so that the Alarm.com Flex IO® sensor is mounted flush to the surface. The magnet also has a zip tie groove across the center. 
    - Zip ties should have a maximum width of 0.34 inches. UV resistant zip ties are recommended.
3. To establish the connection with your Flex, open the battery door and close it tightly.

- The Alarm.com Flex IO® sensor is installed flush to the mounting surface. If the mounting tamper is enabled, the tamper button on the back of the device should be pressed in.
- The LED is not blinking. The only LED activity should occur when the device is activated, which should result in 2 yellow blinks. 
    - For more information on LED patterns, see[ <u>Alarm.com Flex IO® sensor - LED Patterns and Troubleshooting</u>](https://answers.alarm.com/Customer/Website_and_App/Cellular_Sensor/Alarm.com_Flex_IO_sensor/Alarm.com_Flex_IO_sensor_-_LED_Patterns_and_Troubleshooting).
- Device activations are being reported in the history on the website and app.

</div><div><span></span>### **Cellular signal strength**

<div><div>Cellular signal strength can be checked using the following steps.

1. Using a screwdriver, remove the battery door. Leave the battery cover off. The device LED should now be active.
2. Hold the Alarm.com Flex IO® sensor in the installation location.
3. Using a paper clip, push the diagnostic button for 5 seconds, then release. The device LED should now be active.

Once diagnostic mode is initiated, the LED will display the cell signal strength in a continuous loop for 2 minutes based on the patterns below. It may take up to 30 seconds for the signal strength to be acquired.

As you move the device, any changes in signal strength will be displayed by updates to the LED pattern. A signal strength of 2 bars or greater is recommended.
