UTC Fire & Security ACU3-F DUK-Autonomous Control Unit

The UTC Fire & Security ACU3-F DUK-Autonomous Control Unit is an intelligent module designed to provide decentralized fire protection logic in modern addressable systems. It plays a critical role in maintaining operational continuity, especially in large or complex facilities where independent zone control is essential.

This unit enables autonomous responses by processing alarm signals and executing control functions directly, without relying on continuous input from the main fire alarm panel. As a result, the ACU3-F significantly improves response time and system resilience in mission-critical applications.

Designed for high reliability, the unit features a robust enclosure that protects the internal electronics from environmental stress and interference. Moreover, it supports seamless integration with a wide range of compatible fire detection and suppression systems.

Flexibility is one of its main strengths. Users can configure the ACU3-F to activate specific outputs such as relays, fans, fire doors, or notification appliances in response to predefined inputs. This flexibility ensures tailored protection strategies that meet the unique needs of each facility.

Installation is straightforward thanks to its compact design and standardized mounting options. Additionally, the unit includes status indicators for power, fault, and alarm conditions, which streamline diagnostics and maintenance.

The ACU3-F is particularly suitable for environments like airports, data centers, healthcare facilities, and high-rise buildings. In these applications, autonomous functionality ensures reliable local responses even if communication with the main panel is disrupted.
