RF Infrastructure & Protocol Compatibility
The SOLT SB9-2PWH wireless call button is engineered to operate seamlessly within proprietary SOLT on-site calling and paging ecosystems. Transmitting across the dedicated 400 MHz RF frequency band, the transmitter utilizes digital Frequency Shift Keying (FSK) low-power data transmission standards. This protocol architecture ensures high transmission stability, digital signal integrity, and low packet loss across commercial, medical, and industrial environments.
Equipped with an internal PCB antenna providing an omnidirectional 360-degree radiation profile, the SB9-2PWH achieves an unobstructed wireless transmission range of up to 100 meters. For proper system functionality, the unit must be paired with receiving hardware calibrated to decode the 400 MHz FSK transmission standard.
Compatible Central Display Receivers
The dual-button configuration of the SB9-2PWH allows it to send distinct digital signaling codes from each button (such as service and bill requests, or dual attendant call alerts). It integrates directly with fixed visual receivers across central nurse stations, dispatcher desks, and service counters:
- SOLT SM3 Series Receivers: Fully compatible with SM3 series numeric and alphanumeric multi-digit display receivers. The receiver identifies the registered ID of the button and displays the corresponding call code, allowing operators to verify table, room, or bed call sources instantly.
Compatible Mobile Wrist Watch Pagers
For mobile staff requiring immediate alert notification on the move in hospitals, elder care homes, clinics, and hospitality venues, the SB9-2PWH integrates directly with SOLT wearable pagers:
- SOLT SP5 Watch Pagers: Compact, on-wrist alert receivers that pair with the SB9-2PWH to receive real-time numeric alerts upon button activation.
- SOLT SP7 Watch Pagers: Digital multi-call wrist receivers capable of registering specific call types from the SB9-2PWH's dual-button interface, allowing attending personnel to prioritize incoming notifications.
Extended Architectural Coverage via SR5 Repeaters
In facilities with challenging structural layouts—such as multi-story buildings, dense partitioning, or areas prone to RF shadowing from reinforced concrete and structural steel—the SB9-2PWH works in direct coordination with SOLT signal enhancement equipment:
- SOLT SR5 Series Repeaters: Extends the effective wireless transmission reach across shadowed areas and between multiple floor levels. The SR5 captures the 400 MHz FSK signals emitted by the SB9-2PWH transmitter and re-transmits them to remote SM3 display consoles or roaming SP5 and SP7 watch pagers without signal degradation.
System Hardware Compatibility Matrix
| Hardware Category | Compatible Model / Series | Operating Frequency & Protocol | Functional Role in System Architecture |
|---|---|---|---|
| Display Receivers | SOLT SM3 Series | 400 MHz Band / FSK | Fixed visual and audible call identification console |
| Wearable Receivers | SOLT SP5 & SP7 Watch Pagers | 400 MHz Band / FSK | Mobile on-wrist vibration and numeric alert delivery |
| RF Repeaters | SOLT SR5 Series | 400 MHz Band / FSK | Signal boosting across multi-floor and shadowed zones |
Commissioning, Pairing & Operational Prerequisites
Before live deployment across walls, bed frames, or tabletop installations, each SB9-2PWH call unit must be registered to the host receiver or watch pager ID bank. Transmission feedback is visually verified via the integrated LED blink indicator on the white casing upon button press.
To establish autonomous operation, the internal circuit requires 2 x CR2032 coin cell batteries (they are not included), which support an operational lifespan of 18 to 24 months depending on facility call volume. Its IP68-rated enclosure ensures that physical integration remains completely stable even when deployed in areas subject to regular washdown or liquid exposure.
