A fire door lock is designed to keep the door closed during a fire to prevent the spread of flames and smoke, while also allowing for quick and easy evacuation in emergencies. Take the mortise fire door lock as an example, the mechanism of lock and latch must maintain their functionality under high temperatures and pressure to ensure the door remains tightly closed. Additionally, fire door locks often come with heat-expanding seals that block gaps around the door to further prevent smoke and fire ingress. Made from high-melting-point materials like stainless steel, the lock's mechanical structure stays intact at high temperatures, ensuring the door can be quickly opened when needed for safe and rapid evacuation.
5. Fire door lock installation & maintenance
Select the right lock, ensuring it meets the fire door's grade requirements and has relevant certifications. Install it correctly according to the manufacturer's instructions to ensure the door closes properly. For maintenance, regularly check the lock's appearance and test its functions to ensure the latch and deadbolt operate smoothly and the door closes tightly.
