In a high-rise building, evacuation cannot be performed in a single phase; phased (staged) evacuation is essential. Immediate knowledge of fire location and operation of the scenario together with elevator, damper, pressurization, and announcement is mandatory. BYKHY makes addressable systems mandatory in high-rise buildings.
Fire risks in this environment
- Length of Evacuation Time — Necessity of Phased Evacuation
- Vertical Spread of Smoke Due to Stack Effect
- Elevator and Stairwell Pressurization Dependency
- Limited Firefighter Access
- Management of Numerous Devices in a Single System
Regulations and standards
According to BYKHY, an addressable fire detection system is mandatory in high-rise buildings. Integrated design with voice alarm, stairwell pressurization, smoke evacuation, and firefighter telephone is required.
Recommended technologies
High-Rise Building Fire Safety — the right solution combination and the reasons behind it.
Addressable Fire Detection
Mandatory; device-based location, Class A loop, and fault resilience with isolator.
Related products →Voice Announcement (VA/PAVA)
Floor/zone-based directed announcement for phased evacuation.
Related products →Sprinkler (Water Extinguishing)
BYKHY makes sprinkler systems mandatory in high-rise buildings. Since fire stairs cannot reach upper floors, containing the fire within the floor and limiting it by its own head is critical.

Initial response at floor level and firefighters drawing water from dry/wet riser columns.
Related products →Module & Isolator
Compartment separation, triggering of damper/fan/elevator scenarios.

Central monitoring of multi-panel systems and BMS integration.
Related products →Typical system architecture
Class A loops and isolators are planned so that each floor/compartment becomes a separate loop segment. Panels are connected to the network and monitored via graphical software on floor plans. In the cause & effect scenario, elevator parking, damper, pressurization fan, magnetic door, and floor-based announcement are defined; reported to BMS with Modbus/BACnet.
Common field mistakes
- Drawing Class B loops and losing the resilience advantage of the addressable system
- Not using isolators between compartments
- Giving evacuation announcement to the entire building at the same time
- Not linking pressurization and damper scenario to the fire panel
- Filling loop capacity to maximum without reserve for future expansion
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 phased evacuation?
Instead of evacuating the entire building at once, a scenario where the fire floor and adjacent floors are evacuated first and different messages are given to other floors. A voice announcement system is required for this.
