Kidde ANSZM4B2A Zone Module, Class or Class Circuits

The Kidde ANSZM4B2A zone splitter module delivers flexible, reliable audio zone distribution for voice evacuation and emergency paging systems. As a Kidde Commercial control panel module, it takes the ANS speaker output and splits it into multiple supervised circuits—allowing integrators to route audio power to separate zones without redesigning speaker runs. The module supports ANS25, ANS50 and ANS100 systems, reports circuit faults over the I2C communication port, and supervises each circuit for open or short conditions to cut troubleshooting time and improve system uptime. Cascadable design and bright LED indicators make it simple to scale coverage for large facilities and monitor circuit status on-site. In an alarm the ANSZM4B2A defaults to All-Call, while optional manual control (ANSSW8) enables selective paging and zone control when required. Ideal for fire alarm, security and building monitoring projects, this voice evacuation zone splitter integrates with existing ANS installations and helps meet NFPA voice evacuation requirements. Specify the ANSZM4B2A for dependable audio circuit management in commercial, institutional, and industrial security or surveillance applications—contact your sales rep to add it to your next project.
