Arter quarter

Office building

About the project

The Arter quarter, located in the heart of  Tallinn’s financial and business district, combines three interconnected towers into a modern complex. The tallest tower on the west side rises 111 meters and has 28 floors, making it the tallest office building in Estonia today and serving as the headquarters of Swedbank Estonia. The complex is complemented by a 15-story building with office space, dining, and wellness facilities, as well as a 9-story apartment hotel.

Energy-efficient and sustainable solutions were consistently prioritized during construction. All three buildings meet the low-energy standard and are certified according to the BREEAM (Building Research Establishment Environmental Assessment Method) building assessment system. Due to the scale of the project, the building features the largest fire alarm system ever installed in Estonia.

 

About the solution

For the implementation, the customer opted for a combination of high-performance system technology and a high level of reliability. Working together with Alarmest, a long-standing local partner responsible for the installation, we developed a solution that meets the project’s complex requirements. The entire complex was equipped with state-of-the-art fire alarm systems. 

A particular challenge lay in the phased commissioning of the individual buildings: while parts of the fire alarm system were already active, other areas were still in the installation phase. Ultimately, all 15 fire alarm control panels had to be networked with 5,500 MTD 533X multi-sensor detectors. Over the project period from July 2023 to August 2025, a total of approximately 200 emergency call buttons, over 700 different fire alarm system outputs on the site , nearly 1,500 meters of aspiration system piping  connected to 10 central units, and around 10,000 meters linear heat detection cables were installed.

An additional benefit arises during ongoing operations: via a mobile application (Integral Remote), security personnel can flexibly receive alarm notifications on various devices—regardless of their location within the building.
