Electrical Contracting Activities
In 2007, as Üçay Engineering, we asserted our presence in the sector by delivering major projects in system contracting within the field of electrical works. Embracing high-quality energy efficiency, applying technology-driven practices, and leveraging deep experience and operational strength, we continue to take part in significant projects of leading construction companies in our country. Within Üçay Engineering’s electrical operations, we provide services in “Weak Current Systems and Low Voltage Systems.” We continue to serve with a continuously growing team and engineering mindset.
Weak Current Systems
These are the systems that enable information flow and communication within buildings, ensuring the organization and management of control and security. Without weak current systems, a building is merely concrete or timber. It is these systems that give a building its functionality, security, and communications. Supporting the entire information and control flow of a building and forming the basis for all business processes, weak current systems keep the operation of many systems—such as computer networks, internet, building control, voice communication, and security—under control. In addition, they are functional today in systems such as ventilation, heating, plumbing, and sewerage.

Low Voltage Systems
These are systems operating at voltages between 1 Volt (V) and 1000 V. In our country, the voltage used in residences is 220 V, while the three-phase AC used in industry is 380 V. Numerous electrical, mechanical, and electromechanical devices are used in low-voltage systems and installations for operations such as safety, control, and switching. In residences, products such as electrical switches, miniature circuit breakers, breakers, residual current devices, and surge arresters are used. In networks and industrial facilities, products such as reactive power control relays and auxiliaries, energy meters, power analyzers, measuring devices, disconnectors, circuit breakers, contactors, motor protection switches, relays, and starters ensure top-level safety and production quality.

Lighting Fixture Installations
Building automation systems can be applied with ease in residences, shopping malls, factories, stadiums, entertainment centers, and plazas. With today’s technological advancement, building automation systems—facilitating both life and labor by enabling the necessary controls and interventions to be performed from a control center manually or automatically—are used in virtually all new buildings.
People can now check their workplaces or homes before entering, thanks to security cameras. In cases such as burglary, immediate information and intervention can be achieved via computers or mobile phones. Efficiency ranks first among today’s essentials; in this context, we deliver successful applications in efficiency solutions through building automation.

Generator System
Generators are devices that convert mechanical energy into electrical energy—typically using electromagnetic induction. They are similar to motors, which do the reverse by converting electrical energy into mechanical energy. Within generators, there are batteries that convert chemical energy to electrical energy, thermoelectric generators that convert heat energy to electrical energy, and photoelectric circuits that convert light energy to electrical energy.
Contrary to what we might think, generators have a rather simple operating principle. They work like an electric motor but in reverse. The critical point is that the rotational speed of the shaft affects the magnitude of the current, which helps deliver the efficiency we expect from electrical systems.
Lightning Protection and Grounding
To protect electrical installations against lightning, the grounding terminals of surge arresters and all metallic parts in outdoor installations that may be struck—such as the shield conductors of overhead lines and metallic or concrete poles—are grounded via a dedicated grounding electrode. This is called lightning grounding. Lightning grounding is a type of protective grounding; the two grounding systems are interconnected.
The aim of lightning grounding is to carry the overvoltage wave caused by a lightning strike to ground without damaging operating equipment, and to safely discharge strikes on buildings to ground without harming human life or causing fire.
SCADA and Energy Monitoring Automation
Today, keeping energy consumption under control has become essential. The core purpose of energy automation is to use available energy efficiently and minimize risks and losses. With energy automation, in essence:
Energy savings are achieved by identifying consumption points; energy costs are calculated; continuity of supply is ensured and reported; and potential faults are detected in time, allowing prompt intervention.
Medium Voltage Systems
As the Üçay Engineering family, we provide: Design, installation, and operation of transformer facilities up to 36 kV of any power and type; design, installation, and operation of Medium Voltage switchgear cells (Metal Enclosed, Metal Clad) up to 36 kV; design, installation, and operation of Medium Voltage building/kiosk applications (reinforced concrete/metal transformer centers) up to 36 kV; operation and maintenance services for transformer centers in accordance with regulations, including retrofitting and rehabilitation, and fault elimination works.
Public Address and Emergency Announcement System
Public address and emergency announcement systems are used for background music broadcasting in buildings and for evacuation of people in emergencies.
While music broadcasting aims to create a pleasant ambiance in occupied spaces, emergency announcements aim to ensure safe evacuation.
The size of the installation area, the number of zones, the acoustic characteristics of the spaces, and user requirements determine the system design. Systems can range from a single zone to hundreds of zones and from a single announcement point to hundreds of announcement points.
Fire Detection and Alarm Systems
In residences, factories, and educational and healthcare facilities, etc., the system comprises fire sensors sensitive to smoke or flame and a coordinated fire control panel to detect a potential fire hazard. The system is generally designed to give automatic warning; it can also be triggered via manual call points (break-glass units). In both cases, once activated, fire sirens connected to the system issue both audible and visual alarms. The aim is to detect fires at an early stage in all buildings so that the necessary measures can be taken.
In this context, we deliver successful applications in fire detection and alarm systems.
Card Access System
Card access systems consist of a reader and a card issued to individuals; by reading the card, the system records entry/exit times and controls the opening/closing of the relevant door/barrier/turnstile.
Upon reading a card, the system can:
– Automatically open a door/barrier, etc.
– Automatically operate a turnstile entry system.
– Deduct a fee/credit from the card (as in cafeteria tracking systems).
– Or simply report the person’s entry/exit times (as in student dormitory access systems).
With card access systems, entries and exits to a given area can be controlled, and after entry, access to certain sections can be allowed or denied to specific individuals so that everyone moves only in permitted zones. Unauthorized access to restricted areas can be prevented. Today, many different methods are used in access control systems. In addition to proximity cards (containing electronic identification), more professional biometric solutions (Fingerprint Recognition, Iris/Retina Scanning, Facial Recognition) can be used.
TV/IPTV/SMARTV System
What is a Central TV System? It allows building or facility users to watch a predetermined set and number of TV channels through a single coaxial line to apartments or hotel rooms—without satellite receivers and without paying monthly/annual subscription fees to any digital platform (Digiturk, D-Smart, etc.). It is commonly used in mass-housing complexes, estates, lodgings, residences, hotels and resorts, hospitals, and schools, thanks to low cost and high image quality.
Data System
Although the term “data” seems to have emerged with technological progress and increased use cases, it is a phenomenon we have long been part of—often without being aware of its evolution. We continuously, and often unknowingly, contribute to this environment, feeding what we call “Big Data” with a constant stream of information.
Parking Guidance System
With modern life and a growing population, the increasing number of vehicles has not only raised the need for more parking areas but has also made it essential to use existing parking lots more efficiently.
In dense city centers, the need for parking has become a growing problem.
Because limited parking capacity cannot meet demand, various solutions are being developed to utilize existing parking more effectively.
Common problems in today’s parking lots include:
1. Especially in large parking facilities, it is difficult for management to track available spaces in real time. It is impractical for staff to check each area individually.
2. Drivers cannot immediately identify an available space; while searching, they occupy lanes and lose time.
3. Multiple staff members may be needed to direct traffic within the lot, increasing operating costs.
4. Management cannot monitor vehicle movements across different time periods and therefore cannot optimize resources accordingly.
To use parking resources more efficiently and to ensure that drivers can park safely, conveniently, and comfortably while saving time, we develop advanced technological solutions. For this purpose, we created the HızlıPark Ultrasonic Parking Guidance System. This system directs vehicles to available spaces, reduces operating costs, solves the problem of searching for a spot, and optimizes the parking facility.
Central Clock System
This is the technology that enables the control and management of local clocks in buildings from a single center. It consists of a master clock unit and connected local clocks.
The master clock continuously monitors the connected digital and analog local clocks and adjusts them when necessary.
SCADA
The term SCADA is formed from the initials of “Supervisory Control And Data Acquisition.” In Turkish it can be translated as “Consultative Control and Data Acquisition System” or “Remote Control and Monitoring System.” Briefly, it is a general term for a controllable and monitored system composed of computers, communication devices, sensors, and other equipment.
Broadly, it is divided into energy SCADA (Electricity-Water-Natural Gas) and process SCADA (factory/plant automation).
With advances in computing and communications and falling device costs, automation of electricity distribution systems has become technically and economically feasible. For example, with distribution and water automation, networks can be monitored remotely and controlled quickly and effectively, resulting in more reliable, continuous, and high-quality electricity and water supply. System data can be archived and statistical reports can enable the most efficient and economical operations management.
SCADA systems—used for supervisory control and data acquisition of processes—form an infrastructure for production control and tracking in factories together with various tools (RTUs, PLCs, etc.) used to monitor processes (raw materials, production, finished goods tracking, etc.). To the extent that the infrastructure allows, ideal integration with MRP II and ERP systems can be established. The goal is to build the structure necessary to produce more, at higher quality, and at the lowest cost. Achieving the highest efficiency from plant assets requires that managers have full command of operational and production information.
SCADA software packages should undertake the role of infrastructure software in industrial facilities and, by connecting to internal and external networks, enable all layers of the company to work in harmony. SCADA provides everyone across the enterprise with real-time, detailed information accessible at any time.
SCADA systems can be used in a wide range of areas: operating pumps, valves, and flow-measurement equipment in hydroelectric and nuclear power generation, natural gas production and processing plants, and in gas, oil, chemical, and water pipelines; controlling switches on electricity transmission lines spanning kilometers; and balancing sudden load changes on lines.
Today, all facilities and enterprises are moving toward deploying SCADA systems—and the momentum will only increase.
