Maintenance Guide for Fire Rated Mortise Locks

Publish Time: 2025-10-20     Origin: Site




Fire-rated mortise locks are a type of fire safety door lock and are critical components of a building's passive fire protection system. Their core function is to ensure proper door closure and maintain fire integrity during a fire, providing crucial time for occupant evacuation. Regular and proper maintenance is essential not only for ensuring operational reliability and extending service life but also for fulfilling fire safety responsibilities. Effective upkeep reduces replacement frequency and achieves long-term cost efficiency.



Key Maintenance Guidelines:

1. Keep the lock clean. Regularly wipe the fire rated mortise lock surface with a dry, soft cloth to remove dust and debris. Avoid acidic chemical cleaners. Excessive dust can increase friction, cause the lock to operate poorly and accelerate wear.

 

2. Operate the lock regularly, including handle operation and key or thumbturn operation. Regular use helps maintain lubrication and ensures internal mechanisms remain in optimal condition, preventing components from seizing.

 

 3. Avoid excessive force. Do not slam the door when opening or closing it, as this can cause severe impacts on the lock. Excessive force may damage the lock mechanism.

 

4. Conduct regular inspections. Check for smooth operation of the mortise lock mechanism, ensure the mounting screws are tight, and verify that the strike plate is securely aligned. If bolt operation becomes rough or closing resistance increases, also inspect the door hinges and door frame for deformation.

 

5. Always install and replace the locks strictly in accordance with the manufacturer’s instructions. Use only fire door locks with equivalent certifications to avoid compromising the fire protection system.
