LEADERS IN ELECTRIC LATCH RETRACTION
Electric Latch Retraction (ELR)
Since 2012, when SDC launched QuietDuoTM – 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.
Why SDC’s Motorized Electric Latch Retraction?
From retrofit ELR field kits, to exit devices and mortise locksets, all SDC ELR products use the
same motorized technology to provide both latch retraction and dogging (exit devices). All models are grade 1
and UL listed. Because of their low current draw, SDC ELR products can be powered
with the built-in 1 Amp+ power
supply that comes standard in SDC’s AUTO series low energy operators - eliminating the need for a separate power supply!
SDC’s LR100 series retrofit ELR kits not only abolish the need for costly replacements of existing exit devices, but also deliver cost savings on installation of select exit device brands without removing the device from the door. Pushpad depression on select exit device models is also offered.
