Answer:
The Sewa 4 key Button S communicates on 433.92 MHz and pairs wirelessly with Sewa / SEWACall LED receiver display panels and digital wrist pagers, functioning seamlessly alongside single-key or multi-key transmitters in the same installation.
The Sewa 4 key Button S transmitter operates within standard SEWACall wireless paging ecosystems using 433.92 MHz RF protocol:
- LED Receiver Display Panels: Transmits service and cancel calls directly to central digital display receivers located at steward stations, nurse consoles, or supervisor counters.
- Digital Wrist Pager Receivers: Dispatches real-time call notifications directly to mobile wrist-worn pagers used by roving floor attendants.
- Mixed Calling Networks: Operates interoperably in hybrid network deployments combining single-key call buttons and multi-key units mapped to unique receiver addresses.
