STI G3A125RM-EN Momentary Push Button with Shield
Overview
The G3A125RM-EN is a hardwired momentary push button designed for access control and request-to-exit installations where tactile feedback and protective shielding are required. This no-camera variant operates at 12VDC and integrates with networked access control panels via standard wiring—solving the problem of exposed button failures in high-traffic door scenarios. The shield housing protects the button mechanism from weather, dust, and accidental damage while the reset lever and rotating disc provide reliable momentary switching for door strike activation, egress requests, or auxiliary device triggering.
Compatibility
The G3A125RM-EN works with access control panels supporting 12VDC auxiliary outputs and standard dry-contact switching. Compatible with multipurpose control systems that route momentary outputs to door strikes, electromagnetic locks, or request-to-exit logic. Integrates via hardwired COM/N.O./N.C. contacts (momentary configuration). Verify your panel supports direct 12VDC wiring and momentary relay output before ordering; TCP/IP management requires a compatible control node or gateway to bridge hardwired switching to networked systems.
Installation Notes
Mount using the 1/2-inch NPT threaded connection or drill anchor holes for surface mounting. Requires #8 × 1.5-inch screws for bracket attachment. Wiring uses standard COM/N.O./N.C. terminals—follow your access control panel's terminal map to avoid reversed polarity. The button operates momentary (spring-return), meaning it does not latch. Ensure the reset lever is visible and accessible for manual emergency override. Shield housing supports outdoor installation when mounted in protected eaves or under vestibule covers; confirm environmental rating limits with your integrator for full-rain exposure scenarios.
