This contact serves as your go-to solution for perimeter protection zones where you need dependable open/close detection without the bulk of industrial-grade contacts. The magnetic switch mechanism provides consistent gap tolerance, reducing nuisance alarms caused by door settling or minor frame shifts. Installation is straightforward—mount the contact on the frame, position the magnet on the door, wire to your zone input, and you're operational. The white finish eliminates the need for paint-matching on trim work, saving time on residential jobs where appearance directly impacts customer satisfaction.

The GI-29AW works across residential security systems, small office intrusion networks, and any application where you're monitoring standard-swing doors in climate-controlled spaces. It pairs cleanly with hardwired panels, hybrid systems, and zone expanders where you're adding coverage to existing infrastructure. For integrators building out multi-point protection or expanding legacy systems, this contact delivers the reliability your service reputation depends on without the premium pricing of specialized sensors.
