Suprema OM-120 Multiple Output Extension Module for Access and Elevator Control

The Suprema OM-120 Multiple Output Extension Module is a powerful output control unit designed for advanced access and elevator control systems. With support for up to 12 independent output relays per unit, the OM-120 enables precise control over doors, floors, or other access points within a secure building environment. Integrated seamlessly with Suprema’s BioStar 2 platform, it allows for robust elevator management, anti-passback (APB) enforcement, fire alarm integration, and scalable RS-485 communication across up to 31 daisy-chained modules—making it a reliable solution for high-rise buildings, secure zones, and complex access scenarios.

Product Features

12 Relay Outputs Per Unit

Each OM-120 module includes 12 independent relays, enabling fine-grained control for doors, elevator floors, or custom output devices in access control environments.

Elevator Integration Support

Controls up to 192 elevator floors by linking multiple OM-120 units (up to 31), allowing for detailed floor access restriction and monitoring through the BioStar 2 platform.

Anti-Passback and Fire Alarm Zones

Supports APB zones for preventing unauthorized re-entry, and links elevator groups to designated fire alarm zones for emergency safety compliance.

RS-485 Communication with Termination Support

Daisy-chain up to 31 OM-120 units via RS-485 for streamlined and scalable deployment. Includes terminating resistors to ensure signal integrity in long-chain configurations.

Status and Diagnostic LEDs

Multi-color LEDs for each relay, RS-485 connection, auxiliary input, power, and module status provide at-a-glance system diagnostics and feedback.
