Sdc 413NU Exit Device Push Button Spdt Time Delay 630

Product Description

The SDC Security Door Controls 413NU is a green, momentary exit device push button with a single-pole double-throw (SPDT) contact configuration and built-in time delay output. Designed for use in access control and egress systems, this unit provides a reliable request-to-exit (REX) or door release signal when pressed. The 630 finish — a standard stainless steel appearance — suits commercial door hardware installations. Licensed electricians and low-voltage access control technicians are the primary installers of this device in commercial and institutional settings.

The 413NU is used in commercial access control systems where a timed, momentary contact signal is required to release an electric lock or latch upon egress. The SPDT configuration supports both normally open and normally closed wiring arrangements, making it adaptable to a wide range of electrified hardware controllers and panels. The green illuminated button provides a clear visual indicator for building occupants at exit points in office buildings, schools, healthcare facilities, and other commercial environments.

Installation Notes

Installation should be performed by a licensed electrician or a certified low-voltage access control technician in accordance with applicable NEC requirements for access control and egress wiring. Disconnect and de-energize all connected door hardware, lock power supplies, and control panels before beginning any wiring work. Confirm local egress and fire code compliance before finalizing the installation, as exit device wiring requirements may be governed by local Authority Having Jurisdiction (AHJ) guidelines.
