The Von Duprin 040065 Quiet Electric Latch Retraction Retrofit Kit provides 4-foot electric operation for 33, 35, 98, and 99 series exit devices. This kit upgrades existing panic hardware to allow remote latch retraction with quiet electric operation. The system integrates with access control systems to provide secure, controlled entry without manual operation of the exit device.
The retrofit kit maintains the mechanical egress functionality while adding electric capability for authorized entry. Installation works with existing Von Duprin rim and mortise exit devices in the compatible series. The quiet operation reduces noise during electric activation, making it suitable for environments where sound control matters. The kit includes all necessary components for field installation without replacing the entire exit device assembly.
This electric latch retraction system works well in office buildings, schools, hospitals, and other commercial applications where remote access control is needed. The retrofit approach saves money compared to complete hardware replacement while adding modern access control features. The system maintains IBC panic hardware compliance for emergency egress requirements.
