STI G3A429EM-EN Multipurpose Push Button with Shield

Overview

The G3A429EM-EN is a 12VDC multipurpose push button with integral shield enclosure, designed for request-to-exit and auxiliary control inputs in access control systems. The turn-to-reset mechanism allows manual override or momentary activation without requiring system resets—a practical addition in high-traffic entry points where staff need physical override capability. The protective shield guards the button contact surfaces from accidental activation and environmental contact while maintaining visibility of the lower rotating disc, which must remain accessible during operation.

Compatibility

Integrates with standard access control panels and strike circuits supporting 12VDC auxiliary inputs. Works with NC and NO contact switching configurations via the COM reference point, making it compatible with most commercial access control power supplies and monitoring boards. Mounts in standard electrical box cutouts for wall installation. Suitable for retrofit and new construction in commercial, institutional, and secure facilities requiring manual control inputs.

Installation Notes

Operates at 12VDC—verify your power supply can deliver the required current for latching and momentary contact circuits. The lower rotating disc visibility is critical to function; ensure mounting location does not obstruct this component. When anchors are used, drill per installation sheet specifications. Standard #8 x 1.5 inch fasteners recommended. Electrical connections follow NC, NO, COM, and reset lever wiring as detailed in the G3 installation documentation—refer to schematic for your specific circuit configuration before wiring.
