In the world of modern access control, flexibility, simplicity, and future-proof connectivity are key. That’s where Commtel’s Command Unit comes in – a robust 4G access control command unit designed to streamline how entry is managed across a variety of sites, from secure storage facilities and lorry parks, to busy distribution centres and managed parking areas.
But what exactly is a Command Unit, and how does it differ from traditional GSM diallers or 4G controllers?
The Command Unit Explained
A Command Unit is a compact yet powerful 4G switch that enables remote control access to powered entrances – such as gates, barriers, doors, and turnstiles – using a mobile or landline phone. Unlike standard GSM controllers, it offers enhanced functionality, built-in scheduling features, and seamless app-based management, making it a smarter and more scalable solution.
With Commtel’s Command Unit, installers can offer their customers a system that’s as easy to manage as it is to install – all while keeping full control at their fingertips, thanks to the intuitive GCU Companion app.
How It Works
The Command Unit operates using the 4G network, delivering reliable, long-term connectivity even as 2G and 3G networks phase out. When a user calls the unit from an authorised number, it activates a relay via DTMF tones, triggering the opening mechanism of the connected entrance system.
Programming can be done remotely via:
- The GCU Companion app (ideal for end users)
- SMS commands
- By the installer during initial setup using the Commtel Config app.
The unit’s 2-way communication also sends confirmation texts back to users, confirming relay activations or successful programming.
