STI G3A229PO-EN Multipurpose Push Button with Shield
Overview
The G3A229PO-EN is a 12VDC latching push button built into a protective shield enclosure, designed for access control and emergency communication applications where you need a hardened momentary or sustained activation input. The turn-to-reset mechanism (via lower rotating disc) prevents accidental resets and keeps the button in an active state until deliberately cleared — critical for door strike circuits and emergency call panels that must hold their state until acknowledged. This unit delivers both normally open (NO) and normally closed (NC) contact configurations from a common (COM) terminal, giving integrators flexible switching logic for diverse panel architectures.
Compatibility
The G3A229PO-EN is compatible with any 12VDC access control system, emergency communication panel, or standalone door control logic that accepts discrete momentary or latching contact inputs. Common applications include door release circuits, emergency call stations, duress buttons, and building automation trigger inputs. The shield enclosure makes it suitable for indoor wall-mount installations in commercial, residential, and institutional environments where button vandalism or accidental activation is a concern.
Installation Notes
Operates on 12VDC supply — confirm your control panel supplies regulated 12V to the button terminals. Wiring requires three conductors (COM, NO, NC) routed back to your panel's input module or relay board. The unit anchors via 1/2 inch NPT thread mounting (drill point specified in installation sheet). LED indicator on the PCB provides visual confirmation of button state when powered. The rotating reset disc must remain accessible and visible for operator reset — do not obstruct with adhesive labels or covers. No external power supply required at the button itself; all power draws from the panel 12V rail.
