Potter EVX-ATM Voice Evacuation System

Add flexible audio I/O to voice evacuation and security systems with the Potter EVX-ATM audio transponder module. Designed for professional installers, this Potter control panel module lets you interface external audio sources into EVAX panels or route panel audio out to third‑party equipment, improving centralized announcements and audio monitoring across facilities. The card supports a balanced audio input of 1 Vrms into 600 Ω and offers field-selectable output levels (1V, 25V, 70V) to match paging amplifiers and speaker circuits without additional adapters. Isolated input/output paths reduce interference for clearer messages in surveillance and monitoring environments, and activation can be handled by contact closure or signal presence for dependable operation during live or automated events. Compatible with conventional EVAX panels and HMX master panels, the EVX-ATM is ideal for retrofit projects, AV integrations, and auxiliary audio routing. Note: the module is non-supervised and is not UL listed; intended for auxiliary audio integration rather than primary life-safety wiring. Contact our sales team to specify the EVX-ATM for your next security, surveillance, or voice evacuation integration.
