Tüdemsas secures factory with Bosch

Tüdemsas (Turkish Railway Machines Industry) has installed public address and voice evacuation systems based around 50 hemi-directional loudspeakers from Bosch. The loudspeakers were installed throughout three buildings that cover around 50,000m² between them.

Established in 1939, Tüdemsaş repairs freight and passenger wagons and manufactures freight wagons and spare parts. Its factory in Sivas, Turkey has a total area of 287,467m2 with an additional indoor area of 96,000m2. It employs 1,500 people, making Tüdemsaş one of the biggest industrial groups for the international railway market in the Balkans and the Middle East.

Soluations supplier and Bosch dealer Entegre Electronics from Istanbul designed and installed a public address and voice evacuation system at the factory, based around 50 Hemi-directional Loudspeakers from Bosch. The loudspeakers were installed in three buildings and cover around 50,000m².

The public address and emergency evacuation system is controlled and managed from the factory’s head office and security centre. Business calls and emergency announcements can be made from both locations. The security centre uses call stations with keypads. For the head office Entegre Electronics designed PC-based call stations with a graphical user interface that enable on-screen zone selection and both pre-recorded messages and live speech in the selected areas.

It’s a full Audio over IP system. The three existing Praesideo systems, installed in separate locations in the factory, work together. Both audio and contact information are distributed over the IP network. The factory’s existing fibre-optic network configuration allowed optimal freedom in system design. It permitted the public address and voice evacuation equipment such as amplifiers, network controller, call stations and multi-channel interfaces to be located wherever required without having to install lots of additional cabling.

“The Tüdemsaş factory is a very demanding environment,” says Serhat Kacar, project manager, Entegre Electronics. “It’s noisy, with average ambient noise levels around 85 dB, so Bosch’s powerful Hemi-directional Loudspeakers are ideal. It’s also a dirty, dusty and hot environment, so the ruggedness of these speakers is vital. The units are suspended from the 15-meter high ceilings with steel wires.”

Tüdemsaş management are are planning to install Bosch’s Hemi-directional Loudspeakers in 2011 throughout two other factories.

Access control system
Entegre Electronics also installed a control system and CCTV solution from Bosch at the Tüdemsaş factory. The video surveillance system consists of five day/night AutoDome 300 IP cameras with 36X optic zoom, three NightSense FlexiDome IP cameras and eight channel DiBos IP software. The FlexiDome cameras and one of the PTZ cameras are installed at the main entrance while the others are installed on a tower in the middle of the campus for viewing the whole plant.
