Common scenarios for fire locks:
1. Fire doors in public places such as shopping malls, hotels, and cinemas
2. Hospital corridors, stairwells, and ward doors
3. Exit doors of stairwells in high-rise residential buildings
4. Factory warehouses and distribution room doors
5. Crowded areas such as subway stations and stations
Main uses of fire locks:
1. Prevent the spread of flames and toxic smoke
Fire locks can keep the door locks firmly closed at high temperatures, keep the fire doors in a closed state, isolate flames and smoke, and protect escape routes.
Used in conjunction with fire doors, they form effective fire partitions.
2. High temperature resistance, not easy to fail
Fire locks use special materials (such as heat-resistant alloys, non-combustible plastics, etc.), which can maintain structural stability in fires and can still work normally for a period of time under high temperature conditions (such as > 850°C).
Generally pass national or regional standard tests (such as GB12955, EN 12209, UL, BS, etc.).
3. Escape function
Usually combined with **emergency opening function (such as push bar lock)** to ensure that people can escape quickly in a fire and are not trapped.
4. Comply with building fire protection regulations
In public buildings, high-rise residential buildings, hospitals, schools, shopping malls and other places, relevant regulations require that fire doors must be equipped with fireproof locks that meet standards.
