The SKE-ZN4 is a four-zone speaker splitter expansion module for the Silent Knight SKE-450 voice evacuation system (a Honeywell brand). It partitions the SKE-450's 50-watt amplifier output into four supervised speaker zone circuits, allowing zone-by-zone evacuation announcements in mid-sized buildings. Independent zone activation supports phased evacuation strategies — for example, alarming only the affected floor plus adjacent floors during the initial alert. MEA 429-92-E and CSFM listings extend applicability to New York City and California installations. Confirm speaker line voltage, wiring class, and total connected load against the SKE-ZN4 installation guide.
