Solutions supplier and Bosch dealer Entegre Electronics from Istanbul has designed and installed a public address and voice evacuation system at TÜDEMSAŞ, based around 50 hemi-directional loudspeakers from Bosch. The loudspeakers were installed in three buildings and cover around 50,000 m².
TÜDEMSAŞ (Turkish Railway Machines Industry Inc.) repairs freight and passenger wagons and manufactures freight wagons and spare parts. 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.
Bosch says that its hemi-directional loudspeaker has an innovative acoustic design that uses 14 specially positioned speaker drivers combined with advanced filtering to eliminate any flat spots in the frequency response. This gives consistent, high-quality sound reproduction over the whole coverage area and a broad frequency response over the audio range from around 60 Hz to over 17 kHz.
“The TÜDEMSAŞ factory is a very demanding environment,” said 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.”
Entegre Electronics also installed an access control system and CCTV solution from Bosch at the TÜDEMSAŞ factory. The video surveillance system consists of 5 day/night AutoDome 300 IP cameras with 36X optic zoom, 3 NightSense FlexiDome IP cameras and 8 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.
