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 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:

Low-energy, swinging door operators provide hands-free, low-power point of entry door control to help meet all U.S. and Canadian Americans with Disability Act (ADA) requirements for door installations in a variety of locations. We’re going to take a brief look at market trends for automatic doors, features that are driving the trends, some basic information specific to low-energy swinging doors, and application examples.
