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:

There are many different brands of cost effective commercial exit devices on the market. The vast majority of these devices are strictly mechanical. Today’s market demands an Economical Commercial Exit Device with Electric Latch Retraction. Not only does SDC’s S4000 Series Electrified Commercial Exit Device satisfy both market needs for a cost-effective exit device with ELR, but the S4000 also comes standard with Request-to-Exit Monitoring, enabling access control compatibility.
