The SOLT SB9-3XWH is an industrial-grade, three-button wireless calling transmitter engineered with an extended logic architecture (two service call actions and one dedicated cancel action). Operating on the 400 MHz / 433 MHz FSK low-power RF band with an omnidirectional 360-degree internal PCB antenna, the unit provides instant, low-latency dispatch across complex facilities. Encased in a compact 74 mm x 46 mm x 11 mm white impact-resistant polymer housing rated to IP68 standards, the device is engineered for rugged indoor and outdoor deployments requiring dust containment and continuous water immersion resistance.
Hospitality and High-Turnover Dining Venues
In full-service restaurants, outdoor terraces, cafes, and private dining suites, operational bottlenecks frequently emerge from repetitive table-checking and delayed payment handling. The SB9-3XWH provides a structured multi-action workflow that eliminates redundant floor movement:
- Multi-Request Segmentation: The two call buttons can be mapped to independent guest needs—such as general service and bill presentation—allowing floor staff to arrive at the table prepared with the correct tools.
- Self-Correction via Cancel Button: Guests can immediately clear mistaken or redundant alerts using the cancel button, preventing unnecessary server trips.
- Liquid and Ingress Resistance: The IP68-rated seal withstands repeated beverage spills, greasy residues, and high-frequency surface wiping without compromising internal electronics or the dual CR2032 lithium coin cell batteries (they are not included).
- Direct Staff Routing: Signals transmit directly to floor attendants wearing SOLT SP7 or SP5 rechargeable wrist pagers, or route to SM3 series main display panels mounted in kitchen staging zones.
Healthcare Facilities and Clinical Outpatient Suites
In nursing homes, diagnostics centers, rehabilitation clinics, and standalone emergency code units, rapid communication and verifiable response handling are critical. The SB9-3XWH operates as a wireless attendant call bell:
- Bedside Assistance and Nurse Calling: Patients can summon attendant staff using designated call buttons, while attending medical staff utilize the physical cancel button upon entering the room to confirm physical arrival and close the active call cycle.
- Hygienic Maintenance: The smooth white polymer shell and IP68 waterproof enclosure tolerate regular wipe-downs with commercial clinical disinfectants and damp cloths without moisture ingress.
- Centralized Telemetry Logging: When combined with the SOLT SR5-MPR PC monitoring receiver software suite, call timestamps and cancellation response intervals are logged digitally for operational auditing and service performance analysis.
Corporate Facilities and Executive Meeting Rooms
Corporate boardrooms, conference centers, and executive offices require non-intrusive, silent communication lines between meeting leaders, administrative staff, and catering support:
- Discreet Desk-to-Assistant Summoning: The low-profile 11 mm casing adheres cleanly to conference tables, podiums, or desks using double-sided industrial adhesive pads.
- Visual Confirmation: Dual-indicator indirect LED perimeter lighting illuminates the top and transparent bottom crystal housing, providing quiet, visual confirmation to the user that an RF transmission has cleared.
- Campus-Wide Coverage: For expansive multi-floor corporate headquarters, signal reach can be bridged across concrete and structural partitions by integrating intermediate SOLT SR5-BPR RF signal repeaters.
