ELK M1TWA Amplified Way Listen in Interface

Designed to extend audio surveillance and two-way communication across a site, the ELK Products ELK M1TWA amplified two-way listen-in interface simplifies on-site monitoring and response. This audio amplifier module integrates directly with the ELK M1 control to add amplified speakers at keypads, lobbies, or remote security stations and to enable live listen-in where needed. The unit supplies three amplified speaker zones with adjustable volume per zone and a mute option that can be triggered by control outputs—ensuring announcements or paging are targeted and controllable during alarms or routine monitoring. On the input side, three microphone zones each accept up to four microphones to expand coverage for surveillance and two-way communication. Able to drive a combined impedance range of approximately 4 to 32 ohms and powered by 14V DC, the M1TWA is suited for commercial and residential installations requiring reliable audio monitoring and security integration. Installers and systems integrators will appreciate the flexible speaker wiring, per-zone control, and straightforward integration with ELK M1 systems. Add the ELK M1TWA to your security or monitoring setup to improve site awareness and responder coordination.
