Teltonika TRB141 installation

This document is intended for professional installers only, not end users.

Sim Card

The device ships without a SIM card pre-installed. You will need to insert the included SIM card before use.

Wiring and installation

While using the Teltonika device with Unloc offers extensive configuration options, we recommend maintaining the standard configuration whenever possible.

he default configuration is as follows

NC1 / C1 / NO1: Lock control relay (Max 1A @ 30VDC). If your lock requires higher ratings, you must use an external relay.

NC2 / C2 / NO2: Auxiliary relay for door automation (Default). Note: This relay cannot control a second lock.

DI1: Request-to-exit button. Triggers the opening sequence and logs an egress event when connected to ground (⏚).

DI2: Door monitor (optional). Used for door status logging and reducing unlock duration after opening. Should connect to ground (⏚) when door is closed.

Installer-accessible configuration is currently in development. For now, all configuration changes must be made by Unloc support.

Two additional I/O pins are available in the power connector and can be configured as either inputs or outputs. Contact us for a consultation if you require custom configuration.
