The SOLT SB9-3XWH wireless calling transmitter unit (KT reference KTI040120SLTWCS) is engineered for commercial, hospitality, corporate, and institutional facilities requiring structured on-demand communication. Operating over FSK low-power RF data transmission in the 400 MHz band, the 3-button transmitter allows end users to trigger discrete service requests—differentiating between general calls and drink requests—while offering immediate call cancellation directly at the transmitter node.
Hospitality Service Management: Restaurants, Bars, and Dining Lounges
In high-density food and beverage operations, optimizing floor staff routing is critical to table turnover and guest satisfaction. The SB9-3XWH is deployed directly onto guest dining tables, booth partitions, or outdoor patio seating:
- Specific Request Dispatch: Dedicated "Call" and "Drink" buttons allow patrons to communicate exact needs. Floor staff receive targeted notifications rather than generalized alerts, eliminating extra round-trips between floor stations and the bar.
- Call Clearing: The integrated "Cancel" button lets patrons or attending servers reset an active request on the spot, clearing the queue on central SM3 series digital display receiver boards or SP5 and SP7 wrist watch pagers.
- Liquid Exposure Resistance: Rated at IP68 water resistance, the durable white plastic housing withstands spills from beverages, accidental liquid immersion, and aggressive surface wiping protocols during table turnover.
Corporate Boardrooms and Executive Meeting Spaces
Corporate meeting facilities and conference rooms require silent, non-disruptive service summoning during client presentations, executive meetings, and long-session conferences:
- Discreet Refreshment and Support Requests: Meeting organizers can trigger refreshment replenishment via the "Drink" button or request facilities/AV technician support via the "Call" button without interrupting proceedings.
- Visual Confirmation: The casing perimeter features indirect LED illumination that shines around the top and bottom case edges, providing visual feedback to the user upon button press without audible clatter.
- Cable-Free Desk Integration: Measuring 74 mm (W) x 46 mm (L) x 11 mm (H) and weighing approximately 28 grams, the transmitter mounts neatly on executive boardroom tables or lecterns using double-sided industrial adhesive pads, eliminating the need to pull cabling through conference furniture.
Healthcare Service Stations, Clinics, and Care Environments
In outpatient clinics, recovery lounges, diagnostic waiting areas, and nursing stations, the SB9-3XWH functions as an auxiliary, cord-free summoning terminal:
- Service and Assistance Summoning: Patients or attendant staff can dispatch immediate assistance calls to duty personnel wearing SOLT wrist pagers.
- Sanitary Ingress Protection: The IP68 water-resistant sealed enclosure accommodates routine sanitization with damp cloth wipes without risk of moisture penetrating the internal PCB antenna or circuitry.
- Extended Facility Coverage: For complex clinic layouts with thick concrete barriers, transmitters can link reliably with central receivers by incorporating SOLT SR5 range repeaters to circumvent structural RF attenuation.
Deployment Considerations and Infrastructure Integration
Because the unit relies on an integrated internal 360-degree omnidirectional PCB antenna, installation is not restricted by directional orientation. Power is delivered independently by CR2032 coin cell batteries (they are not included), allowing rapid retrofitting onto tables, reception counters, or walls without electrical infrastructure changes or conduit installation.
