The Sewa Model KW1P Wireless Nurse Call Washroom Pull Cord Unit (KTI SKU: KTI0401200WNPCB) is specifically designed to provide localized, high-reliability emergency call triggering across institutional, commercial, and medical facilities. Operating via Amplitude Modulation (AM) at 433.92 MHz, the unit delivers a wireless transmission signal across an open-air range of up to 100 meters. Its surface-mount footprint measuring 85 mm x 85 mm x 10 mm and lightweight 0.275 kg ABS plastic enclosure allow it to be installed directly on walls in critical utility areas without complex structural trenching or AC mains cabling.
Inpatient Hospital Wards and Specialized Clinical Washrooms
In acute care hospitals, specialized clinics, and surgical recovery centers, wet rooms and patient toilets represent high-risk zones for slips, falls, and post-operative fainting. The Sewa KW1P is mounted adjacent to the toilet seat, positioning the extended mechanical pull cord within reach of patients seated or incapacitated on the floor. When pulled, the unit triggers an immediate wireless emergency broadcast. The 2-key configuration also integrates a localized cancel button on the 85 mm x 85 mm faceplate, requiring attending medical staff to enter the washroom to verify patient safety before resetting the active emergency state.
Nursing Homes and Assisted Living Facilities
Long-term care and assisted living environments require accessible alerting hardware that requires minimal physical effort to actuate. The low-resistance drop-down cord mechanism of the Sewa KW1P allows residents with limited hand strength or mobility impairments to easily initiate a call. Because the unit is powered by an internal 23A-12V battery (they are not included) drawing a low 10 mA operating current at DC 12V, it remains fully operational during local facility mains power outages, maintaining an unbroken safety layer for vulnerable residents.
Corporate Offices and Conference Facilities
Facility managers deploy the KW1P inside corporate office restrooms, executive washrooms, and conference room facilities to support modern occupational safety protocols and accessible washroom compliance. The compact 10 mm depth profile ensures the ABS faceplate integrates flush against finished tile or drywall partitions without impeding traffic in compact cubicles. Its 433.92 MHz RF transmission links directly with designated security desk receivers or audible corridor annunciators across commercial floor plates up to 100 meters away in open line-of-sight.
Hospitality Venues and Commercial Restrooms
High-turnover public washrooms in restaurants, banquet halls, and commercial complexes utilize the KW1P to provide patrons with a direct emergency link to management or security personnel. The resilient ABS housing withstands everyday commercial washroom humidity, while the 100% wireless architecture permits rapid retrofitting into existing washroom tiles without drilling electrical conduits.
