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

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. It also comes equipped with input and output options for integrating compatible devices that lack long-range connectivity.

<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>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.

1. Open the magnet to trigger the sensor. The LED should blink yellow twice when the device is tripped. This prompts the Alarm.com Flex IO® sensor to communicate.
2. The install wizard will verify if your device is working properly. If there are no errors, the sensor installation is now successfully complete.

- 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.

# What is the Cat-M cellular network?

**GoSafer Security Knowledge Base**

*This operational reference is organized for GoSafer Security customers and staff. Alarm.com product names are retained where required for technical accuracy.*

## Overview

The Cat-M network is a portion of the LTE cellular network, dedicated to low-power Internet of Things (IoT) devices. Compared to traditional (Cat-1) LTE, it has a smaller bandwidth and slower upload speeds but is capable of handling significantly more devices through its unique way of controlling traffic on the cell towers. One of the primary advantages of Cat-M is that it utilizes flexible power-saving modes to drastically increase the battery life of devices. For example, Cat-M devices like Alarm.com Flex IO® sensors communicate over the cellular network when needed (for example, when the sensor is opened or closed, tampered with, or has a low battery) and conserve power when the device is idle. Note: Alarm.com Flex IO® sensors are currently only available on CAT-M Verizon and CAT-M AT&amp;T.
