Sdc 474U Touchless Exit Switch

Product Description

The SDC - SECURITY DOOR CONTROLS 474U is a touchless exit switch designed for access control and egress applications. It allows personnel to activate door release hardware without physical contact, reducing surface contamination risk in high-traffic facilities. The 474U fits into the category of exit devices and push buttons, making it a practical solution for electricians and security integrators who need reliable, code-compliant egress signaling. The contactless sensing mechanism triggers the door release circuit without requiring the user to touch any surface, supporting both hygiene and operational efficiency in commercial and institutional environments.

The 474U is suited for commercial, institutional, and light-industrial door access installations where touchless egress is required. Typical applications include hospitals, schools, office buildings, and other facilities where hands-free door activation improves workflow and meets health or accessibility requirements. It is installed by licensed electricians or low-voltage access control technicians as part of a complete door hardware and access control system.

Key Features

• Touchless sensing technology eliminates the need for physical contact to trigger door release
• Designed for exit device and push button egress applications
• Suitable for commercial and institutional access control systems
• Sold individually as a single unit

Compatibility

Designed as an OEM-style replacement or new-installation touchless exit switch for commercial access control and egress systems requiring a contactless push button device.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage access control technician. Disconnect and de-energize all related door hardware and access control circuits before beginning installation. Follow applicable NEC requirements for low-voltage wiring and local building codes governing egress hardware. Verify the sensing zone clearance and mounting height comply with ADA and local accessibility guidelines before finalizing placement.
