The SOLT SB9-2PWH wireless call transmitter is engineered to deliver discrete, low-latency assistance paging across commercial, healthcare, and corporate environments. Featuring a dual-button interface within a compact snow white enclosure measuring 74 mm (W) x 46 mm (L) x 11 mm (H) and weighing approximately 28 grams, this compact unit facilitates multi-tier request routing across a 400 MHz RF frequency band using Frequency Shift Keying (FSK) modulation.
Clinical and Patient-to-Nurse Paging
In healthcare environments—including hospitals, specialized outpatient clinics, nursing homes, and elder care facilities—the SB9-2PWH serves as a reliable bedside or bathroom call point for rapid caregiver signaling. The unit’s IP68 ingress protection rating ensures complete resistance against dust and continuous water ingress, permitting routine surface decontamination with hospital-grade liquid sanitizers and damp cloths without risking component failure or short circuits.
Upon activation, an integrated visual LED blink indicator confirms signal transmission, providing reassurance to patients and staff. The internal PCB antenna broadcasts an omnidirectional 360-degree RF signal spanning up to 100 meters in open field conditions, relaying calls directly to centralized SOLT alphanumeric display receivers (such as the SM3 series) or mobile staff carrying SOLT SP5 and SP7 wrist watch pagers.
Hospitality and Table Service Optimization
In high-turnover dining operations—including full-service restaurants, hotels, cafes, and food courts—the dual-button layout is optimized for service differentiation. By default, the two operational buttons can be designated for distinct actions such as "Service" and "Bill" requests. This division eliminates customer delays, reduces unassisted waiting periods, and streamlines floor staff workflow by indicating the exact nature of the guest's requirement before approaching the table.
Because the unit is sealed to IP68 standards, it withstands accidental beverage spills, routine dining room wash-downs, and continuous tabletop handling. Powered by 2 x CR2032 coin cell batteries (they are not included) providing an estimated operational life of 18 to 24 months, the transmitter functions continuously without requiring hardwired cable drops or disruptive facility modifications.
Corporate Boardrooms and Office Automation
For executive meeting rooms, conference facilities, and corporate reception areas, the SB9-2PWH supports discreet attendant calling. Acoustic disruptions during high-level meetings are eliminated, as users can summon administrative, IT, or catering support silently with a single button press. Signals pass through office partitions to alert designated support staff carrying SP5 or SP7 watch pagers.
