The SEWACall K-H2 is a compact 60 mm x 60 mm x 22 mm wireless transmitter designed to provide instant, two-way operational signalling across commercial, industrial, and institutional environments. Operating on a 433.92 MHz radio frequency using AM modulation, the device delivers an open-air transmission range of up to 100 meters. Powered by a DC 12V circuit drawing 10 mA operating current via a 23A 12V battery (they are not included), the unit integrates two distinct tactile functions—Call and Cancel—within a 100% waterproof enclosure to streamline internal service workflows.
Corporate Cabins and Executive Meeting Rooms
In modern corporate offices, administrative facilities, and boardrooms, the SEWACall K-H2 functions as an on-demand attendant and peon calling interface. Installed directly onto conference tables or executive desks without external signal cabling, the unit allows personnel to summon support staff to cabins or meeting spaces with a single press of the Call key. The RF transmission links directly with centralized SEWACall LED display receiver panels located in pantry areas or administrative desks, as well as mobile attendant wrist pagers. If an attendant request is resolved or initiated by mistake, pressing the dedicated Cancel key immediately updates the receiver status, preventing redundant foot traffic and administrative delays.
Hospitality Facilities: Restaurants, Cafes, Bars, and Hotels
Commercial dining and entertainment venues deploy the SEWACall K-H2 across guest dining tables, private booths, bar counters, and outdoor patio seating to enhance service response times. In these high-turnover environments, the 100% waterproof construction protects internal electronics from liquid spills, beverage splashes, and routine surface sanitation. Patrons initiate service or billing requests via the Call button, transmitting an alert across the 433.92 MHz frequency to floor managers or waitstaff equipped with receiver watches or station displays. Floor attendants can clear active alerts on-site using the Cancel key once the patron's request has been addressed.
Healthcare Clinics and Outpatient Care Centers
In healthcare facilities, day-care clinics, and diagnostic centers, the SEWACall K-H2 provides an accessible call point for patient-to-attendant alerting. Placed at bedside stations, examination rooms, or recovery bays, the 60 mm x 60 mm x 22 mm profile offers straightforward, high-visibility interaction for individuals requiring assistance. Signals transmit across the DC 12V radio frequency network up to 100 meters in open areas, registering immediately on central monitoring displays at nurse or attendant stations.
