The SOLT SB6-2XWH-S / SB6-3XWH-S emergency pull cord transmitter (SKU: KTI040120SLTSB62) operates within the unified SOLT wireless calling ecosystem. Built for attendant, waiter, and nurse call systems, the transmitter functions as an autonomous peripheral that broadcasts distinct digital call and cancellation signals across commercial and healthcare facilities without dedicated control cabling.
400 MHz FSK Wireless Protocol and Signal Architecture
Wireless communication between the SB6 pull cord unit and centralized receivers is conducted via FSK (Frequency-Shift Keying) low power data transmission standards in the 400 MHz band. The unit incorporates an internal PCB antenna engineered to deliver a 360-degree omnidirectional RF propagation pattern. This omnidirectional transmission ensures dependable signal transfer from inside enclosed wet areas, accessible restrooms, and partitioned washrooms to receiving equipment situated throughout corridors or central stations.
Central Display Panel Compatibility
The SB6-2XWH-S and SB6-3XWH-S transmitters are directly compatible with SOLT master receiver monitors and annunciator panels, including:
- SOLT SM3 Series Multi-Digit Displays: Full integration with models SM3-32PN, SM3-33PC, and SM3-61PC. These multi-channel master stations decode the incoming 400 MHz RF signal and display the originating washroom, room, or bed number.
- SOLT SM7 Series Central Displays: Compatible with SM7 numeric display consoles for centralized alert processing at nurse desks, security consoles, and attendant duty stations.
When the 1-meter twisted pull cord is triggered, the transmitter broadcasts an emergency call code that registers on the receiver display alongside high-brightness LED confirmation on the transmitter itself. Pressing the separate integrated Cancel button sends a distinct clearing command that resets the visual and audible alarm queue on the paired SM3 or SM7 panel.
Corridor Dome Lights and Mobile Pagers
For facilities requiring multi-tier alarm routing, the SB6 pull cord transmitter directly interoperates with SOLT secondary annunciation hardware:
- SOLT SL6 Series Corridor Indicator Dome Lights: Stationed above washroom doorways or patient room entrances to provide rapid visual location confirmation when a pull cord is activated.
- SOLT SP7 Series Wrist and Watch Pagers: Allows mobile nursing staff, orderlies, and facility attendants to receive immediate alphanumeric wrist alerts directly from washroom calling points while away from central monitoring desks.
System Hardware Compatibility Matrix
| Hardware Category | Compatible SOLT Series / Models | Integration Function |
|---|---|---|
| Main Annunciators | SM3 Series (SM3-32PN, SM3-33PC, SM3-61PC), SM7 Display | Station identification, queue management, and tone alerting |
| Corridor Lighting | SL6 Signal Lamp Series | Over-door optical alerting outside washrooms and cubicles |
| Mobile Paging | SP7 Series Wrist Pagers | Direct wireless dispatching to moving care and service staff |
| Transmitter Peripherals | SB6 Series Calling Buttons | Coexists on identical RF frequencies within mixed wireless topologies |
Because the unit relies entirely on independent internal coin cell batteries (they are not included), integration requires no physical interface with local building power circuits, simplifying retrofits alongside existing SOLT wireless receivers.
