The SOLT SB7 series 1-button wireless cancel call point in black (SKU: KTI040120SLT1XBK) delivers point-of-service alert termination across critical communication networks. Built with a double-molded enclosure featuring a scratch-resistant urethane upper surface and an IPX8 waterproof rating, the device operates over the 433 MHz RF band using FSK modulation. Designed to interface directly with wireless receivers, it eliminates lingering notification alerts, manages response accountability, and streamlines multi-staff workflows without requiring hardwired infrastructure.
Healthcare and Clinical Nurse Call Systems
In hospitals, nursing homes, and outpatient clinics, the SB7 cancel transmitter operates as a bedside or point-of-care call acknowledgment station. When a patient summons assistance using a call unit, staff arriving at the bedside press the dedicated cancel button to terminate the call cycle. This transmission sends an RF signal via its internal 360-degree omnidirectional PCB antenna to clear active alerts instantly from central SOLT SM3 series multi-digit display receivers (such as SM3-23PC, SM3-33PC, or SM3-61PC) and mobile staff wrist pagers (including SP7-100 and SP5-200). Visual transmission verification is provided immediately to the operator through integrated indirect dual LEDs.
By clearing alerts directly at the patient's bedside, the unit prevents duplicate dispatches and ensures that clinical staff have physically attended to the patient before the notification queue clears. The non-porous urethane finish withstands routine wipe-down sanitization using standard hospital disinfectants without compromising the double-molded seal.
Patient Washrooms, Showers, and Wet Environments
Facilities requiring call-reset verification inside damp or washdown zones benefit from the unit's IPX8 waterproof enclosure, engineered to IEC/EN 60529 immersion standards. Standard deployments include assisted living bathrooms, barrier-free accessible restrooms, hospital shower stalls, wellness spa areas, commercial pools, and marine yacht spaces. Because the sealed casing prevents moisture ingress and environmental degradation, facility managers can mount the unit directly inside wet areas using double-sided mounting tape or wall brackets without running low-voltage electrical conduits.
Hospitality, Dining, and Executive Attendant Paging
In high-capacity hospitality venues, luxury dining environments, and corporate executive suites, the cancel transmitter acts as a service coordination tool. Once an attendant answers a summons at a private dining booth, VIP lounge, or executive meeting room, depressing the cancel point informs the broader hospitality team via wearable SP series pagers that the request is fulfilled. Powered by 2 x CR2032 lithium coin cell batteries (they are not included) providing an operational lifespan of 18 to 24 months, the device maintains continuous service availability without disrupting operations for power connection work.
