An incident earlier this year highlights misconceptions about using or not using Delayed Egress on emergency exit doors.

On New Year’s Day at Salt Lake City International Airport, a Utah man died after he breached double doors at an airport emergency exit stairway in the secure area of the passenger terminal, ran across the tarmac, and crawled into the engine of a plane awaiting deicing. His family said he had a history of mental illness and suspect he was experiencing a manic episode.

Prior to his gaining access to the runway through the stairway double doors, he was thwarted in several attempts to gain access to the jetway at a gate door secured by an SDC EMLock® paired with an exit bar and door trim. It should be noted that SDC’s electrified hardware solutions are used on every jetway gate door at this airport.

Solenoid Controlled Mortise Locksets

Ensure the safety of your building occupants with fire exit doors that comply with code regulations. Discover how solenoid controlled mortise locksets can enhance security while meeting the necessary requirements.

Understanding Fire Door Code Compliance

Understanding the requirements for fire exit doors is crucial for maintaining a compliant and secure environment. One of the key aspects of fire door code compliance is the installation of proper hardware, including solenoid controlled mortise locksets.

Exploring Solenoid Controlled Mortise Locksets

Solenoid controlled mortise locksets are a popular choice for fire exit doors due to their enhanced security features and ability to meet code regulations. These locksets use an electric current to control the locking and unlocking mechanism of the door and provide controlled access to the building. This enhances the security of the building while still allowing for quick and easy egress in case of an emergency.

Moreover, solenoid controlled mortise locksets are designed to meet the necessary fire door code requirements which ensures that the locksets contribute to the overall fire safety of the building. These locksets provide a reliable and efficient solution for controlling access and maintaining the safety of your building occupants.

Motorized electric latch retraction (ELR) systems are becoming increasingly popular in access control applications. These systems provide a convenient and secure solution for controlling entry and exit points in various commercial and institutional settings. With a motorized ELR, the latch can be retracted remotely, allowing for easy passage through a door without the need for physical contact. This not only enhances convenience for users but also minimizes the risk of unauthorized access or tailgating. Motorized ELRs are often integrated with other access control technologies such as card readers or biometric systems, providing a comprehensive and efficient security solution. Additionally, these systems can be easily installed and configured, making them suitable for both new installations and retrofit projects. With their reliable performance, smooth operation, and advanced features, motorized ELRs are revolutionizing access control and setting new standards for convenience and security.
