A fire door mortise is a crucial component in the construction and safety of fire-rated doors. As a supplier of fire door mortises, I have witnessed firsthand the significance of these products in safeguarding buildings and their occupants. In this blog, I will delve into what a fire door mortise is, its functions, types, and why it is an essential element in fire protection systems.
What is a Fire Door Mortise?
A fire door mortise is a specialized lock or hardware fitting that is designed to be installed within a recess (mortise) cut into the edge of a fire door. Unlike surface-mounted locks, mortise locks are embedded within the door, providing a more secure and aesthetically pleasing installation. Fire door mortises are engineered to meet specific fire resistance ratings, ensuring that they can withstand the effects of fire and heat for a specified period.
Functions of a Fire Door Mortise
Fire Resistance
The primary function of a fire door mortise is to maintain the integrity of a fire door during a fire. Fire-rated mortises are constructed from materials that can withstand high temperatures without losing their structural integrity. This helps to prevent the spread of fire and smoke through the door, providing valuable time for occupants to evacuate the building and for firefighters to control the blaze.
Security
In addition to their fire resistance properties, fire door mortises also provide security for the building. They are designed to resist forced entry, making them an effective deterrent against intruders. Many fire door mortises feature advanced locking mechanisms, such as deadbolts and anti-pick pins, which enhance their security features.
Ease of Use
Fire door mortises are designed to be easy to use, even in emergency situations. They typically feature a simple key or lever operation, allowing occupants to quickly and easily open the door in the event of a fire. Some fire door mortises also include panic hardware, which can be activated by pushing a bar or lever, further facilitating a rapid evacuation.
Types of Fire Door Mortises
Fire-rated Mortise and Silence Mortise Lock
The Fire-rated Mortise and Silence Mortise Lock is a popular choice for fire doors in commercial and residential buildings. This type of lock combines fire resistance with a silent operation, making it ideal for areas where noise is a concern, such as hospitals, schools, and hotels. The fire-rated mortise ensures that the door maintains its integrity during a fire, while the silence feature reduces the noise generated when the lock is operated.


High Security Mortise Lock
The High Security Mortise Lock is designed for applications where enhanced security is required. This type of lock features advanced locking mechanisms and anti-pick technology, making it highly resistant to forced entry. High security mortise locks are commonly used in banks, government buildings, and other high-security facilities.
Fire Door Mortise
The Fire Door Mortise is a standard lock designed specifically for fire doors. It is engineered to meet the fire resistance requirements of building codes and standards, ensuring that the door can effectively contain fire and smoke. Fire door mortises are available in a variety of styles and finishes to suit different door designs and architectural requirements.
