Motorized ELR for Access Control

Posted by Kerby Lecka on February 2, 2024 at 10:00 AM

BlAST_ELRExitDevices_HERO_010324Motorized 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.

SDC Hybrid Power Supplies Meet the Unique Needs of Access Control Locking Devices

Posted by Kerby Lecka on November 9, 2023 at 10:00 AM

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.

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 lock-sets with factory-installed ELR and automatic door operators with a built-in 1 Amp+ power supply to power them.

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.

SDC's AUTO Operators Work Well With Electric Latch Retraction Applications

Posted by Security Door Controls on April 22, 2022 at 10:00 AM

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:

  • Built-in 1 Amp+ power supply
  • Single-button, self-tuning setup
  • Onboard lock sequencing
