Procedure

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.

Features

Detect open/close using magnetic reed switch

Detect state change for third-party device using Loop Input

Change state of third-party and device using Relay Output (requires DC power to support always-on cellular connection)

For more information about supported use cases, see Alarm.com Flex IO® sensor - Supported Use Cases.

In the box

Optional EOL (end of line) resistor to detect cut wires. EOL resistor can be 300 kΩ or higher. Normally Open configuration is preferred for low power usage.

Optional mount tamper and battery door tamper alerts

Multiple mounting options, including screws or zip ties.

Multiple carrier options

Verizon (US only)

AT&T (US and Canada)
