Alpha AM333 Auxiliary Relay for QuickBus Station Integration

Add reliable external device control to your QwikBUS intercom deployment with the Alpha Communications AM333 auxiliary relay. This compact relay adapter converts a station call into a normally-open, dry contact closure so you can trigger strobes, loud bells, alarm inputs or other separately powered devices directly from the intercom call event. Designed specifically for QwikBUS series intercom and video-intercom stations, the AM333 draws power from the station through an easy plug-in wiring harness, eliminating the need for separate power wiring and speeding installation.

Built as a surface-mount module with a small footprint (approximately 1.8" x 0.8" x 1.3"), the AM333 is an unobtrusive way to expand security and surveillance capabilities without major cabinet changes. Installers benefit from a straightforward plug-and-play connector and compatibility with existing Alpha Communications QwikBUS systems. Use it to integrate external monitoring, notification, or alarm systems into your intercom workflow for improved site safety and faster response. Upgrade your intercom-based security and monitoring setup with the AM333—order today to add auxiliary control to your QwikBUS stations.
