High structure evacuation cannot be done at once; phase evacuation is essential. It is imperative that the fire location is known immediately and that the scenario works together with the elevator, damper, pressurization and announcement. BYKHY requires an addressable system in high-rise buildings.
Fire risks in this environment
- Length of evacuation period — phased evacuation obligation
- Vertical spread of smoke by chimney effect
- Elevator and stair pressurization dependency
- Limited access to fire brigade
- Managing multiple devices in one system
Regulations and standards
According to BYKHY, an addressable fire detection system is mandatory in high-rise buildings. Integrated design with buzzer, ladder pressurization, smoke evacuation and fireman phone is required.
Recommended technologies

Addressable Fire Detection
Mandatory; device-based location, Class A cycle and fault resistance with insulator.
Related products →Voice Announcement (VA/PAVA)
Floor/zone based guided announcement for progressive evacuation.
Related products →Sprinkler (Water Extinguishing)
BYKHY makes the sprinkler system mandatory in high-rise buildings. Since the fire brigade ladder cannot reach the high floors, it is vital that the fire is limited to the floor with its own head.

Class A cycles and insulators are planned so that each floor/compartment has a separate cycle segment. Panels are connected to the network and monitored through the floor plan with graphic software. In the cause & effect scenario, elevator parking, damper, pressurization fan, magnetic door and floor-based announcement are defined; reported to BMS by Modbus/BACnet.
Common field mistakes
- Losing the durability advantage of an addressable system by taking a Class B cycle
- Not using insulators between compartments
- Announcing evacuation of the entire building at the same time
- Failure to connect the pressurization and damper scenario to the fire panel
- To fill the cycle capacity to the full and not to leave a margin for the future
Frequently Asked Questions
Is an addressable system mandatory in a high-rise building?
Yes. According to BYKHY, an addressable fire detection system is mandatory in high-rise buildings.
What is progressive evacuation?
Instead of evacuating the entire building at the same time, it is the scenario where the fire floor and the neighboring floors are evacuated first and different messages are given to the other floors. The voice announcement system is necessary for this.
