Olarm LINK Smart IO Expander

Description

The Olarm LINK Smart IO Expander is a powerful yet easy-to-use device that adds smart control and monitoring to your Olarm system. It allows you to manage gates, garage doors, lights, pumps, and other equipment remotely using the Olarm App.

Because it integrates directly with an Olarm PRO communicator (required), the Olarm LINK helps turn ordinary electrical devices into smart, connected assets. As a result, you gain better visibility, improved automation, and greater peace of mind — all from one platform.

Key Features

• 6 configurable I/O ports that work as inputs or open-drain outputs

• 2 high-current relays for switching AC or DC devices

• Analog sensor input supporting voltage or current sensors

• DIN rail mountable design for neat, professional installations

• Tamper detection and status LED for added security and clarity

• Expandable system supporting multiple LINK modules on one bus

In addition, the compact design makes it ideal for control panels where space is limited.

Benefits for Homes & Businesses

Smart control from anywhere

With the Olarm LINK, you can control connected devices remotely using your smartphone. Therefore, you always know what is happening on your property, even when you are away.

Improved automation and safety

By linking inputs and relays to events, the system can trigger automatic actions. For example, lights can switch on when a gate opens, or alerts can be sent if a pump fails.

Flexible installation options

Because the ports are configurable, the same device works across many applications. As a result, installers can use one solution for multiple use cases.

Built for South African conditions

Designed to work reliably with modern security systems, the Olarm LINK is well suited to residential, commercial, agricultural, and industrial environments across South Africa.

Common Use Cases

• Automating electric gates and garage doors

• Switching lights, beams, or external equipment

• Monitoring pumps, tanks, or machinery status

• Adding inputs or outputs to alarm and security systems

Because of this flexibility, the Olarm LINK is popular with installers, estates, and businesses that need reliable remote control.

How It Works

First, the Olarm LINK is installed on a DIN rail inside a control panel.
Next, it connects to an Olarm PRO communicator using the supplied cable.
Then, the installer configures inputs, relays, and notifications in the Olarm App.
Finally, the system is ready to monitor and control devices in real time.
