The SOLT SR5-BPR RF transceiver repeater (SKU: KTI040120SLT5BPR) is purpose-engineered to integrate seamlessly into commercial and industrial wireless calling architectures. Operating on the 433 MHz frequency band with FSK/GFSK modulation and a temperature-compensated crystal oscillator (TCXO) circuit, the repeater provides bidirectional signal acquisition and re-transmission with an RF output power of up to 10 mW. It bridges spatial gaps and overcomes structural radio-frequency attenuation between wireless calling transmitters and receiving endpoints.
Compatible SOLT Wireless Call Buttons and Endpoints
The SR5-BPR features an integrated registration capacity capable of pairing and relaying transmissions from up to 999 discrete wireless call buttons. Device registration is executed directly over the air using the rear 1.3-inch LCD configuration display, which supports sequential bell ID assignment for high-density deployments.
- SOLT SB Series Wireless Call Buttons: Fully interoperable with the entire SB series transmitter family, including SB3, SB5, SB6, and SB7 models.
- Registration Capacity: Memory registers up to 999 individual transmitter addresses without requiring physical cable connections.
- Power Supply Decoupling: The repeater operates continuously via its external AC 110–240V to DC 12V, 1A power adapter and does not rely on secondary dry cells or internal backup batteries (they are not included).
Compatible Central Receivers, Displays, and Pagers
Incoming alerts boosted by the SR5-BPR are re-broadcast transparently to central alerting, monitoring, and mobile paging units operating across the facility. The forwarded 433 MHz FSK/GFSK transmission preserves all original transmitter ID payloads and functional call codes.
- SOLT SM Series Central Display Receivers: Compatible with wall-mounted multi-call display units, including the SM3 and SM7 receiver consoles.
- SOLT SP Series Mobile Pagers: Direct signal forwarding to staff wrist pagers and belt receivers, including the SP5 and SP7 mobile terminals.
- PC Interfacing and Logging Modems: Native compatibility with SOLT computerized alert logging and monitoring modems, including the SR5-MPR and SR5-MPRT receiver bridges.
Multi-Repeater Deployment and Loop-Prevention Architecture
Large-scale facilities such as multi-floor hospitals, corporate campuses, clinics, nursing homes, and extended hospitality venues can scale their coverage footprint using multi-unit repeater layouts. The architecture imposes no artificial restriction on the number of SR5-BPR units operating concurrently across a shared wireless environment.
To maintain RF integrity in dense overlapping installations, the SR5-BPR incorporates user-definable transmission delay times (TX delay) and duplicate call restriction intervals. Configured via the rear 1.3-inch LCD screen, these transmission timers eliminate ping-pong looping, repeater bounce, and packet duplication across adjacent repeaters.
