RF Signal and Wireless Transmitter Interoperability
The Sewa K14S Wireless Nurse Call Panel (SKU: KTI0401200WUK14) operates on an RF receiver frequency of 433.92 MHz utilizing Amplitude Modulation (AM). The internal receiver board is engineered to pair with up to 250 wireless call transmitters across healthcare facilities, patient wards, and critical care units. Operating without physical interconnect cables, the unit receives direct wireless call signals from patient-side hardware across the 433.92 MHz band.
Peripheral transmitter compatibility includes standard healthcare calling buttons as well as specialized long-cord bed call buttons designed for bed-bound or serious patients. Because wireless transmitters operate autonomously across the matched 433.92 MHz AM protocol, facilities can expand transmitter deployments incrementally up to the maximum 250-node threshold without redesigning central hardware infrastructure.
Addressing and Display Format Compatibility
To support systematic facility-wide addressing, the receiver's front interface features a 4-digit alphanumeric display supporting identifiers ranging from 000 to FFFF. This broad hex-compatible alphanumeric range enables granular identification across multi-floor and multi-ward hospital architectures.
- Display Capacity: Displays 1 group of active calls simultaneously in the primary visual field.
- Addressing Range: Alphanumeric indexing from 000 through FFFF for bed, room, ward, or emergency pull station designations.
- Call Queue Capacity: Internal register stores up to 32 active incoming calls in system memory.
- Delay Reminder Alert: Integrated built-in delay alert triggers to notify nursing staff if queued patient calls remain unaddressed.
Wrist Monitor and Station Eco-System Integration
The K14S display panel integrates seamlessly within wider hospital communication architectures that employ wireless personal or nurse wrist monitors. In an integrated operational setup, wireless patient buttons broadcast signals simultaneously to both the stationary K14S sheet metal receiver panel mounted at the nurse station and wearable wrist receivers carried by mobile floor personnel. This parallel compatibility ensures that emergency call alerts are logged visibly at the central station while dispatching immediately to roving staff.
Software Integration and Management Support
The K14S receiver architecture includes support for management software integration. Healthcare IT and facilities administrators can link the receiver with compatible logging software packages to track incident call times, monitor response intervals, log call frequencies, and centralize operational reporting for institutional audits.
