STI G3A429LD-EN Multipurpose Push Button Flush Mount
Overview
The G3A429LD-EN is a 12VDC flush-mount push button with integrated audio output, designed for access control door-entry applications where you need momentary activation feedback. The NC/NO/COM switching configuration supports both fail-safe and fail-secure strike wiring—pick the terminal set that matches your door control logic. Mechanical reset lever and rotating disc allow field reconfiguration without tools, reducing commissioning time on mixed-architecture deployments.
Compatibility
Works with standard access control systems and door strike controllers accepting 12VDC momentary switch inputs. Compatible with fail-safe (energized to lock) and fail-secure (de-energized to lock) architectures via terminal selection. Fits standard electrical wall boxes and surface-mount enclosures common in commercial security installations. Verify your strike controller supports direct 12VDC switch input before installation.
Installation Notes
Mount in 1/2-inch NPT threaded hole or standard wall box. The reset lever must be visible and unobstructed for manual operation. Integrated sound output operates from the 12VDC supply—no separate audio power required. Confirm NC/NO/COM terminal assignment before wiring to strike controller to avoid polarity-dependent failures. Button housing is recessed flush to wall surface, reducing snag risk in high-traffic entries.
