The SOLT SB9-3XWH wireless calling transmitter bell operates within the manufacturer's proprietary wireless infrastructure using standardized Frequency Shift Keying (FSK) low-power data transmission. Operating across the 400 MHz / 433 MHz RF frequency band with an integrated omnidirectional 360-degree PCB antenna, the unit delivers seamless, cable-free communication with centralized monitoring consoles, personal pagers, network repeaters, and software-integrated receivers across hospitality, corporate automation, and healthcare facilities.
Central Display Receivers (SOLT SM3 Series)
The SB9-3XWH is fully compatible with SOLT SM3 series wall-mount central receiver display panels, including models SM3-33PC, SM3-61PC, and SM3-22PN. These master displays receive the omnidirectional FSK transmissions and decode the specific 3-button logic of the transmitter (differentiating between the two distinct call functions and the dedicated cancel action). Key architectural compatibility points include:
- Air Registration Protocol: Transmitter Bell IDs register directly over-the-air to the SM3 receivers without hardwired programming cables.
- Network Capacity: SM3 master panels register and coordinate up to 1,000 individual bell IDs simultaneously, allowing large-scale deployment across multiple operational zones.
- Display State Tracking: Master panels dynamically reflect the state changes initiated by the transmitter, instantly clearing visual and audible alerts when the dedicated cancel button is pressed.
Wearable Mobile Pagers (SOLT SP Series)
For roving attendants, nursing staff, or service personnel, the SB9-3XWH interfaces directly with SOLT SP5 and SP7 series wireless rechargeable wristwatch pagers, such as the SP7-100. The wrist units process the FSK signal independently or in parallel with central displays:
- High-Density Mapping: Wearable units support monitoring configurations of up to 900 unique bell IDs.
- Multi-Action Decoding: The pager firmware correctly parses the SB9-3XWH unit's multi-button messages, distinguishing call types (e.g., service requests versus billing requests) and logging immediate cancel triggers to prevent unnecessary staff travel.
Signal Repeaters and Enterprise Range Extension
In facilities with significant structural attenuation—such as multi-floor medical centers, reinforced concrete structures, or extended outdoor dining zones—the SB9-3XWH is fully compatible with the SOLT SR5-BPR RF signal booster repeater. The repeater receives the low-power 400 MHz / 433 MHz transmission from the transmitter and regenerates the packet at full signal strength to ensure error-free reception at remote display terminals or wrist pagers.
PC Data Logging and Management Interfaces
For operational analytics and dispatch tracking, the SB9-3XWH interfaces with the SOLT SR5-MPR PC monitoring receiver software suite. This integration enables real-time enterprise management features:
- Data Logging: Automatically timestamps each transmission event, logging the exact elapsed duration between initial call generation and subsequent button cancellation.
- Dynamic Mapping: Supports both Stack Type and Map Type visual operational layouts on host PCs for immediate dispatch tracking.
Ecosystem Hardware Compatibility Matrix
| Hardware Category | Compatible Model(s) | Integration Method | Functional Role |
|---|---|---|---|
| Master Wall Displays | SM3-33PC, SM3-61PC, SM3-22PN | 400 MHz / 433 MHz FSK (Over-the-Air) | Centralized multi-channel visual and acoustic call display |
| Wearable Pagers | SP7-100, SP5 Series | Direct FSK RF Reception | Mobile staff notification with multi-button text/code parsing |
| RF Range Extension | SR5-BPR Signal Booster | FSK Repeating | Overcomes physical obstructions and extends line-of-sight distance |
| Analytics / PC Receiver | SR5-MPR Receiver & Software | Wireless RF to USB/PC Terminal | Digital event recording, performance tracking, and table mapping |
To preserve signal integrity and operational readiness across this ecosystem, the SB9-3XWH requires two CR2032 lithium coin cell batteries (they are not included), which provide continuous operation for an estimated 18 to 24 months under standard call volumes while maintaining the housing's IP68 ingress protection seal.
