Technology met with magnificence..
The Hagia Sophia is an enormous architectural marvel in Istanbul, Turkey, that was originally built as a Christian Basilica nearly 1,500 years ago. However, its function has changed several times in the centuries since.
Challenges
Since it is an old and historical building, in case of a fire, there is a risk of fire spreading much faster and causing damage compared to modern buildings. For this reason, the building was in need of a fire detection system that was safe, stable and would not damage its historical texture.
In addition, there was an architectural difficulty that did not allow any infrastructure work, including cabling, which could damage the structure texture. As a result of all these, the fire detection need of the building was met with Teknim Wireless Fire Alarm Systems.
Solution
In order to prevent damage to the historical structure, the security of the environment was ensured with TWD-1850 Wireless Multiple Detectors at all points where the cabling infrastructure could not be applied.
The high dome of the prayer area in the mosque caused the need to provide detection with Beam Detectors and a module connection was required to transmit alarm-fault conditions to the Fire Alarm Panel. However, since cabling between the module and the panel was not possible, TWM-1887 Wireless I/O Modules were used to transmit alarm and fault information to the panel.
Since the wall thicknesses at many points were about 4-5 times thicker than normal buildings, this situation adversely affected the signal transmission distance of wireless devices at some points. In addition to this, the fact that there was a very dense circulation of visitors inside the mosque created a separate source of difficulty in terms of signal quality. In order to overcome both challenges, TWM-1886 Routers, which can only work with 24V DC supply and do not need any additional connection, were placed at certain points of the mosque. In this way, the thick wall structure of the mosque and the density of people negatively affecting the signal levels were eliminated.
With Mosaic Graphic Monitoring Software, the entire system is monitored live, helping the authorities to intervene quickly in possible dangerous incidents.
