Factory Installed Motorized ELR

The SDC S5000 is a heavy duty, code compliant alternative to magnetic locks that meets the market need for a storefront exit device with electric latch retraction for access control upgrades. Nightlatch functionality* is available through the use of a rim key cylinder for medium and wide stile doors making these exit devices perfect for industrial, healthcare and education aluminum glass applications.

Explore the benefits of motorized electric latch retraction in storefront exit devices, including options for Request-to-exit and Latch Status capabilities. Discover the features of the SDC S5000 exit device and how it can optimize your code compliant entrance upgrades.

Motorized ELR For Access Control

Not only does SDC’s S4000 series of electrified industrial exit devices satisfy market demand for a cost-effective exit device with ELR, the S4000 also comes standard with request-to-exit (REX) monitoring, enabling access control compatibility. With a host of additional features and options, S4000 exit devices make application as easy as Install - Power - Done.

Discover the advantages of motorized electric latch retraction in industrial exit devices, including cost-effectiveness and enhanced security. Explore the features of the SDC S4000 exit device and how it can optimize your facility's safety measures.

Electric Latch Retraction (ELR)

Since 2012, when SDC launched QuietDuo™ – the first Motorized ELR Kits to convert mechanical exit devices – we’ve been “quietly” leading in electric latch retraction (ELR) upgrades for access control. This includes retrofit solutions for most brands of exit devices as well as innovative SDC exit devices & mortise locksets with factory-installed ELR and automatic door operators with a built-in 1 Amp+ power supply to power them. Discover the transformative potential of electric latch retraction technology in revolutionizing security systems and enhancing protection.

Discover how electrified options can revolutionize access control systems, enhancing security, architectural aesthetics, and code compliance.

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.

1 – 6 Amp Access Control Power Supplies

In 1994 SDC introduced the 602 power controller – the first hybrid supply to combine the efficiency (low heat generation) of switching power supplies and the rugged inductive load handling capability of linear power supplies to meet the unique needs of access control locking devices. 

Unlike camera system power requirements, access control systems draw more current for locking hardware and during access control-related events. As the industry transitions from solenoid-based electric locking devices to motorized devices, demand for specific power supply requirements has also increased. 

SDC’s 12/24VDC class 2 hybrid power supplies have been designed specifically to meet these needs and reduce power system issues with extra filtering, heavy-duty circuitry for inductive loads and multi-door applications, and an isolated battery charging circuit to protect locking devices and components from over voltage while the batteries are charging. With the addition of SDC programmable controllers or relay modules, the user-friendly modular designs ensure versatility, interface capability and easy installation of virtually any electric locking devices, access controls and related fire life safety equipment.

With advancements in electric motor technology, the use of a motor for electric latch retraction provides lower current draw, quieter operation, and greater durability over time vs. solenoids. 

Electric Latch Retraction (ELR)

SDC's AUTO series operators can power all of SDC's motorized ELR products.

Why should you care?
AUTO series operators eliminates the need for a separate power supply to power latch retraction products with it's own built in 1 Amp+ power supply! 

Since 2012, when SDC launched the QuietDuo™ LR100 series – the first retrofit motorized ELR kits to convert mechanical exit devices – we’ve been “quietly” leading in electric latch retraction upgrades for access control.

SDC now provides these same high performing motorized ELR features in the new American Made S5000 series storefront and S4000 series industrial electrified exit devices.

The new electrified devices, in addition to the existing LR100 series retrofit ELR kits and 7600 series motorized ELR mortise locks are conveniently compatible with low energy operators including SDC's AUTO series.

Highlights of our AUTO series operators include:
