Installation requirements for fire warning and evacuation management systems

The installation of warning and evacuation control systems is carried out in accordance with the Law of 01.10.2029 N ZRU-226 “On Fire safety” and the rules of 20.10.2020 N 649 “Fire Safety Rules” dated 20.10.2020 N 649 and the manufacturer’s technical documentation. The purpose of these systems is to promptly and clearly inform people in the event of a fire in order to organize timely evacuation.

When designing and installing, the type of warning and evacuation control systems is taken into account, depending on the functionality and area of the facility. There are 5 types of systems: from simple sound systems (type 1-2) for small buildings to multifunctional complexes (type 3-5) that provide voice notification, direction indication, and division of an object into zones to create a staged evacuation.

The method of laying cable lines

Fire-resistant cable products (FRLS, FRHF) laid in metal pipes or ducts are used for warning and evacuation control systems. The routes are carried out along the load-bearing elements, in protected channels. Only cables that do not lose their functionality during a fire during a specified time are allowed.

Arrangement of system elements

The speakers and indicators are placed evenly so that there are no gaps in audibility in each zone. The sound level must exceed the background noise by at least 15 dB, and the speech clarity must be at least 75%. Additionally, light direction indicators are installed, visible from anywhere in the room.

Integration with other systems

Warning and evacuation management systems are integrated into the overall architecture of fire protection — in conjunction with APS, smoke extraction systems, elevator shafts and ACS. Upon receiving a signal from the fire sensors, the alarm and evacuation control systems are automatically activated in a preset logic for each zone of the facility.

Power supply and redundancy

Two-channel power supply and backup power sources are provided for alarm and evacuation control systems. The allowed battery life of the system is at least 24 hours in standby mode and at least 1 hour in emergency mode.

Acceptance and inspections

When the system is put into operation, checks are performed: measuring the sound level at control points, checking voice messages, evaluating the visibility of direction indicators, testing the logic of switching between different evacuation zones. The permissible sound level deviations are not more than 5%.

The installation of warning and evacuation management systems is carried out by organizations licensed by the Ministry of Emergency Situations of the Republic of Uzbekistan. Only certified equipment and fire-resistant cable products are allowed. The quality of the installation is checked as part of a commission check, the results are documented in certificates. Strict compliance with these requirements ensures stable and efficient operation of warning and evacuation management systems in fire conditions.
