The SOLT SB6-3XWH-1PSR wireless call button bed unit (KT reference SKU: KTI0401200WSLTB) is engineered for rapid deployment across healthcare wards, geriatric centers, nursing homes, and assisted living facilities. Operating on an autonomous 400 MHz FSK wireless transmission architecture, the system completely removes the need for wall-chasing, hardwired conduit routing, or structural data cabling between patient rooms and central nursing stations.
Transmitter Wall Mounting and Placement Guidelines
The compact transmitter base unit measures 100 mm (W) x 60 mm (L) x 16.5 mm (H) with a weight of 50 g. It should be mounted on the architectural headwall or adjacent vertical wall surface directly beside the patient bed. For optimal ergonomic access by medical personnel, position the wall unit at standard bedhead console height, ensuring clear line of sight for the high-brightness call confirmation LED indicator.
Because the unit utilizes a built-in omnidirectional 360-degree antenna, direct physical line-of-sight between the wall unit and receiving hardware is not mandatory. However, avoid mounting the transmitter inside fully recessed metallic enclosure boxes or behind dense metal structural plates, as this can attenuate RF transmission in the 400 MHz band.
Flexible Cord and Hand Unit Deployment
The unit features a dedicated bedside extension tethered by a 120 cm flexible cord. Depending on the specification ordered, the 1 PSR cable assembly connects via a curled (P) or straight (PS) cord profile. Secure the wall base unit first, then extend the flexible 120 cm lead to the patient's bedside or bed rail so mobility-restricted patients can trigger call alerts without reaching for the wall station.
- Cord Profile: 120 cm flexible cord assembly with integrated handheld call pendant.
- Key Functions: Compatible with 2X (call/cancel) and 3X (2 call/cancel) button functional configurations.
- Cable Connection: 1 PSR cable assembly interface directly coupled to the base transmitter.
Power Source and Battery Installation
The transmitter operates fully wirelessly and requires 2 x CR2450 coin cell batteries (they are not included). Before fixing the rear mounting enclosure to the wall surface:
- Open the base chassis of the 16.5 mm slim transmitter housing.
- Insert 2 x CR2450 coin cell batteries (they are not included), observing the polarity markings embossed on the battery terminal clips.
- Snap the base casing shut securely to maintain mechanical integrity. Depress the call button on the handheld pendant to confirm that the high-brightness LED illuminates, validating active battery power.
System Registration and Display Pairing
Each SOLT SB6 series transmitter is assigned a unique digital ID selected from a factory range of 16 million discrete Bell IDs, eliminating duplicate RF collisions across adjacent hospital wings. To register the unit into the facility network:
- Set the receiving display—such as the SOLT SM3 series (including SM3-22PN, SM3-23PC, SM3-33PC, or SM3-61PC)—into RF registration/learning mode.
- Trigger the call signal using the bedside hand unit. The receiver captures the unique 16-million-range Bell ID broadcast over the 400 MHz FSK link.
- Assign the desired room or bed number to that specific transmission address on the receiver display.
- If wrist-worn mobile receivers are deployed, program the transmitter ID into nurse pagers such as the SP5, SP7, or SP9 series.
- Pair with corridor alert lamps (SL6) if local hallway visual annunciation is required.
Range Testing and Multi-Floor Scalability
Perform an end-to-end activation test after mounting. Press the pendant key from the patient bed, verify that the high-brightness LED illuminates, and confirm instantaneous reception at the nurse station display or mobile pagers. For multi-story buildings, sprawling medical wards, or areas with thick reinforced concrete partitions, incorporate SOLT SR5-BPR multi-stage repeaters along transmission pathways to boost and relay 400 MHz FSK signals without structural wiring.
