The Commtel 4TGCU Command Unit is a compact 4G access control solution designed to provide secure remote operation of gates, barriers, doors and other powered entrances using a mobile phone. Ideal for residential, commercial and industrial sites, it allows authorised users to open, latch or close entrances remotely, eliminating the need for traditional fobs or keypads.
Supporting up to 1,300 authorised telephone numbers, the 4TGCU is suitable for everything from private driveways to busy logistics centres, storage facilities and secure parking areas. Its integrated 4G LTE connectivity ensures long-term network compatibility, while remote programming, time-based access scheduling and cloud-based management through the CIRRUS platform make administration simple and efficient.
Easy to install and configure, the 4TGCU features two-way communication with confirmation messages, a volt-free input, programmable relay operation and multiple access modes, providing installers with a flexible and reliable access control solution for modern automated entrance systems.
Features
- Dial-to-Open Convenience: Store up to 1300 authorised numbers to allow easy entry by calling the unit from an authorised number, ideal for multi-user sites.
- Remote Control & Feedback: Control the entrance from anywhere via mobile or landline. The unit confirms relay activations with a return text, offering peace of mind that your command has been actioned.
- 4G Connectivity: Equipped with a 4G/VoLTE module for reliable, long-term connection, future-proofed beyond the 2G/3G network phase-out.
- Programmable Time Profiles: On-board the clock supports 9 remotely configurable time profiles, enabling timed access (e.g. weekday entry only, or auto-latch at specific times).
- Low Power Mode: Ideal for solar-powered installations, optional low-power configuration reduces energy consumption without compromising functionality.
