SDC LR100MBSK LR100 Series Electric Latch Retraction Kit for QF1100/QF1200 Exit Devices, Field Install, 24VDC

Enable electric access control without sacrificing life-safety compliance with the Security Door Controls LR100MBSK electric latch retraction kit. Designed as a field-install retrofit for QF1100 and QF1200 exit devices, this LR100 Series electrified deadlatch motorizes latch retraction and dogs the pushpad—allowing momentary or sustained push/pull operation while preserving uninhibited egress. The kit operates on 24VDC and features low current draw, making it simple to integrate with access control panels, building automation or remote control devices. Because it is panic and fire rated, you get reliable security upgrades that meet code requirements for emergency exits while supporting monitoring and surveillance systems for centralized management. High-traffic durability and compatibility with low energy operators make this solution ideal for schools, hospitals, commercial offices and other critical infrastructure. For installers and security integrators looking to convert mechanical exit devices into electrified, monitored openings, the LR100MBSK is a compact, effective option.
