About this product .

The SOLT SB9-3XWH wireless calling transmitter is housed in a compact, durable white casing designed to withstand demanding high-traffic service environments. Engineered with an IP68 ingress protection rating, the unit resists accidental water spills, beverage splashes, and regular surface disinfection without risking electronic degradation.
Equipped with an advanced FSK low-power data transmission module operating within the 400 MHz band, the transmitter ensures robust short-range radio communication resistant to local electromagnetic interference. Signal radiation is distributed through an internal PCB antenna providing a 360-degree omnidirectional pattern for consistent signal reception from any angle.
The unit features a dedicated three-key tactile layout configured for Call, Drink, and Cancel functions. When a button is pressed, an indirect LED confirmation halo illuminates both top and bottom casing sections to provide intuitive visual feedback to the user and confirm that the transmission has triggered.
This transmitter integrates seamlessly into the complete SOLT wireless paging ecosystem. It pairs directly with SOLT SP7 and SP5 wrist watch pagers worn by service staff, SM3 digital receiver display panels mounted at service counters, and SR5 RF range repeaters for large multi-floor venues.
Installation is completely wire-free and versatile, allowing quick deployment on restaurant dining tables, corporate desks, bar counters, or bedside hospital stations using industrial double-sided adhesive pads or optional bracket mounts.
The unit is powered by CR2032 coin cell batteries that deliver extended operational life due to low-power standby circuits. Maintenance consists of periodic surface wiping using a soft cloth and timely replacement of the coin cells when the visual confirmation LED dims.

SOLT SB9-3XWH System Compatibility & Hardware Integration

Wireless Ecosystem Architecture

The SOLT SB9-3XWH wireless calling transmitter (KT reference: KTI040120SLTWCS) is engineered for full architectural interoperability across the genuine SOLT wireless hardware ecosystem. Operating on frequency-shift keying (FSK) low-power data transmission standards within the 400 MHz / 433 MHz radio frequency spectrum, the device transmits digitally encoded control packets via an integrated 360-degree omnidirectional internal PCB antenna. This standardizes signal distribution across on-premise receiver hardware without channel cross-talk or frequency drift.

The 3-button interface generates dedicated digital identity codes corresponding to Call, Drink, and Cancel functions (2 call functions and 1 cancel function). These distinct RF status signals ensure seamless protocol interpretation by upstream receiving endpoints, enabling automated workflow handling across hospitality floor staff, corporate office meeting attendants, and healthcare care-station personnel.

Compatibility with SOLT Receiver Displays and Mobile Pagers

The SB9-3XWH integrates natively with SOLT receiving endpoints without requiring external protocol translation bridges, interface converters, or secondary signal gateways. Supported receiver equipment includes:

SOLT SM3 Series Digital Display Receiver Boards: Centralized numeric and alphanumeric display panels designed for wall mounting or counter placement in nurse stations, kitchen dispatch counters, or host stands. The SM3 series interprets the 3-button multi-code transmissions to display table or station IDs alongside active service status codes (call or drink requests) and immediately flushes the active alert upon receiving the corresponding cancel payload.
SOLT SP7 Wrist Watch Pagers: Mobile wearable digital receivers worn by service attendants, floor servers, and technical staff. The SP7 receiver decodes incoming 400 MHz / 433 MHz FSK alerts to deliver immediate haptic and visual notifications with station identification and specific call/drink attributes.
SOLT SP5 Wrist Watch Pagers: Compact wearable paging receivers engineered for roving staff, supporting direct message logging and real-time operational status updates directly from SB9-3XWH transmitter units.

Range Extension and Signal Propagation Compatibility

For installations where building layouts present dense structural barriers, such as thick reinforced concrete walls, interior elevator shafts, or multi-level architectural footprints, the SB9-3XWH transmitter is fully compatible with SOLT SR5 wireless range repeaters. The SR5 unit captures omnidirectional 400 MHz / 433 MHz FSK signals transmitted by the transmitter's internal PCB antenna and re-broadcasts them at extended range, eliminating packet loss and maintaining total signal integrity between caller buttons and receiver displays.

Power Source Interfacing	CR2032 Coin Cells	Powered independently by replaceable CR2032 coin cell batteries (they are not included) without hardwired electrical feeds.

Mounting and Physical Infrastructure Compatibility

Because the SB9-3XWH transmitter operates completely cable-free with an ultra-compact footprint measuring 74 mm (W) x 46 mm (L) x 11 mm (H) and an approximate weight of 28 grams, it requires no cutouts, electrical conduit, or structural modifications. The IP68 water-resistant white plastic casing integrates effortlessly into hospitality tabletops, dining counters, conference desks, bar tops, or vertical wall mount locations using double-sided industrial adhesive pads or dedicated mechanical mounting base accessories. Autonomous operation using CR2032 coin cell batteries (they are not included) ensures that transmitter deployment does not interfere with existing electrical circuits or building management system (BMS) wiring infrastructure.

Application Scenarios and Operating Environments for SOLT SB9-3XWH

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.
