Mertsat, who has implemented the "FIRST" and "ONLY" high security prison application of Turkey, presents both mechanical and electronic designs in electronic door monitoring systems to its business partners. Some of these designs implemented are as follows:
- Triple lock mechanism design with locking from a single point
- Wall-type camera protection design
- High security door design
- Fixed seating group design
- Lock-free door holding mechanism (Ball system)
These systems, which were created by Mertsat's experience, were designed and implemented by identifying the prison needs. The systems are designed to ensure that inmates use their own rooms in accordance with the authorities set by the prison administration. Thanks to programmable logic control units (PLC) with approximately 8,000 inputs and 4000 outputs, not only gate control but also automated prisoner counting can be performed.
