Interlogix NX-534E Two-Way Voice Module

The Interlogix NX-534E is a two-way voice module designed for use with NetworX control panels. It works with the alarm panel's PSTN dialer to enable monitoring operators to listen to or communicate via voice after an alarm is triggered.

This module supports several modes including call-back, call-in to hear audible conditions, and speaker lockout during duress signals. It features two microphone inputs, one output, and an X-10 interface supporting up to nine devices. Control and commands are handled remotely through DTMF tones.
