Mechanical Wall-Mounting and Enclosure Positioning
The Sewa K14S Wireless Nurse Call Panel is engineered for fixed vertical wall-mount deployment within healthcare facilities, hospital wards, nursing stations, and duty supervisor desks. The panel features a durable sheet metal housing with overall physical dimensions measuring 295 mm x 145 mm x 50 mm. When planning panel placement, select an elevated, central wall location at the nurse monitoring station where the 4-digit alphanumeric display remains clearly visible to staff members managing emergency alerts.
Because the panel operates via 433.92 MHz radio frequency communication, installers should secure the unit to a sturdy vertical surface away from large enclosed metallic ductwork or high-voltage switchgear that could shield or attenuate wireless reception. Its rugged sheet metal body construction ensures stable mounting and long-term structural integrity in busy hospital environments, requiring minimal physical maintenance post-installation.
Power Supply Requirements and Electrical Connection
The Sewa K14S receiver panel requires a regulated operating power input of DC 12V 1A. Because transmission between calling points and the master panel is entirely wireless, facility teams do not need to run structural signal cables through hospital walls or conduit between patient rooms and the central nurse station. Installers only need to provide a dedicated, stable DC 12V 1A power feed at the primary mounting position. Ensure polarity and rated DC voltage match panel requirements prior to energizing the unit.
Wireless Pairing and Device Configuration
The Sewa K14S system utilizes AM (Amplitude Modulation) at 433.92 MHz and provides an onboard pairing capacity for up to 250 wireless transmitters. During system commissioning, technical teams enroll peripheral calling hardware directly into the receiver memory. The panel is fully compatible with:
- Standard wireless patient bed call buttons
- Long cord call buttons engineered for serious or bed-bound patients
- Peripheral wireless components within the network, including wireless personal or nurse wrist monitors
If any peripheral calling units or mobile wrist monitors require operational battery cells (they are not included), verify that the cells are fully charged and seated properly prior to initiating the registration sequence. Each paired calling device can be programmed with an alphanumeric address ranging from 000 to FFFF, allowing clear room-by-room and bed-by-bed mapping across the healthcare facility.
Operational Verification and Queue Configuration
Once paired, the unit displays 1 group of active calls simultaneously on its high-visibility digital display. The internal memory of the K14S manages an active queue capacity of up to 32 calls, logging simultaneous emergency signals and rotating active alerts when multiple rooms trigger calls at the same time. The panel also includes an integrated delay reminder function, ensuring unacknowledged calls generate recurring alerts until attended by nursing personnel.
