SDC’s Electra™ 7200 series solenoid controlled cylindrical locks replace most brands of mechanical locksets in commercial, industrial and institutional openings. Discover the numerous advantages of electrified cylindrical locksets for building security and why they are a reliable choice for facility managers and owners. 

Enhanced Durability & Resistance to Physical Abuse

Cylindrical locksets are known for their enhanced durability, making them a reliable choice. These locksets are designed to withstand daily wear and tear, ensuring that they can withstand the test of time. With their sturdy construction and high-quality materials, solenoid controlled cylindrical locksets offer long-lasting security for facilities.

One of the key advantages of cylindrical locksets is their increased resistance to physical abuse. Cylindrical locksets are built with robust mechanisms and reinforced components that make them highly resistant to tampering or forced entry. These heavy duty, electric cylindrical locksets stay latched even when unlocked, maintaining fire door integrity and eliminating reliance on exposed and vulnerable electric strikes, magnetic locks or request-to-exit devices.

Maintaining Fire Door Integrity

Maintaining fire door integrity is crucial for the overall safety of your building, and solenoid controlled cylindrical locksets offer a reliable solution for this important aspect of security. Fire doors are an essential component of building safety, as they help prevent the spread of fire and protect occupants in the event of an emergency.

Electrified cylindrical locksets are equipped with features that ensure they meet fire code requirements and support the integrity of fire doors. These locksets are tested and certified to withstand high temperatures and maintain their functionality during a fire. By choosing solenoid controlled cylindrical locksets for your fire doors, you can trust that your property is equipped with reliable security measures that prioritize safety in case of emergencies.

Integration with Access Control Systems

Solenoid controlled cylindrical locksets are not only reliable in terms of security but also offer seamless integration with access control systems. Access control systems provide an added layer of security by allowing authorized individuals to enter your property while restricting access to unauthorized individuals.

Electrified cylindrical locksets can be easily integrated with access control systems, allowing you to manage and monitor access to your facility more efficiently. This integration enables you to use advanced features such as keyless entry, remote access control, and audit trails to enhance the overall security of your property.

By choosing cylindrical locksets that can be integrated with access control systems, you can enjoy the convenience and peace of mind that comes with advanced security technology.

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.
