Sdc 424U Green Exit Momentary Dpdt Push Button 630

Product Description

The SDC - SECURITY DOOR CONTROLS 424U is a momentary double-pole double-throw (DPDT) exit push button with a green actuator and a 630 stainless steel finish. Momentary DPDT push buttons are used in access control and door release systems to signal an exit request without latching in the pressed position. The 424U is designed for installation in commercial and institutional door hardware applications where a clean, durable, and code-compatible egress signaling device is required. Licensed security and low-voltage technicians typically install this type of device as part of a complete electric locking or access control system.

The 424U is suited for commercial interior doors in office buildings, healthcare facilities, schools, and similar environments where controlled egress is required. The green actuator provides a clear visual indicator for occupants, and the 630 stainless steel finish coordinates with standard commercial door hardware. This push button integrates with electric strikes, magnetic locks, and access control panels that accept a momentary dry-contact DPDT input.

Installation Notes

Installation is typically performed by a licensed low-voltage or access control technician. De-energize the access control panel and any connected electric locking hardware before wiring. Follow all applicable local codes and manufacturer wiring diagrams when connecting the DPDT contacts to the control panel. Verify switch polarity and contact configuration at the panel before restoring power.
