The SOLT SB7 series 1-button cancel transmitter (black finish) is engineered for cable-free surface mounting across healthcare facilities, commercial hospitality venues, and industrial estates. Because the device operates entirely via wireless radio frequency transmission, it eliminates the labor and infrastructure costs of conduit runs, core drilling, or electrical wiring. With a low-profile physical footprint measuring 60 mm in diameter, 15 mm in thickness, and weighing approximately 29 grams, the SB7 provides unobtrusive placement on walls, patient bed heads, nursing stations, workbenches, or tabletop surfaces.
Surface Preparation and Mechanical Mounting
The unit supports two primary mechanical mounting methods depending on the operational environment and surface texture:
- High-Adhesion Industrial Double-Sided Tape: Suitable for smooth, non-porous surfaces including architectural glass, laminated patient headboards, polished acrylic panels, ceramic tiles, and smooth metallic fixtures. The substrate surface must be thoroughly cleaned of grease, moisture, and dust before firmly pressing the base plate into position for optimal bonding.
- Designated Wall Mounting Brackets: Recommended for rough drywall, masonry, or high-impact service zones where mechanical bracket fastening is preferred. The mounting plate attaches securely to the vertical surface, allowing the compact 60 mm diameter enclosure to seat securely against vibration and repeated physical presses.
Thanks to its IPX8 continuous water immersion rating and fully sealed double-molded case with a scratch-resistant urethane upper layer, the SB7 can be mounted directly inside wet facilities, assisted living bathrooms, patient shower cubicles, swimming pool decks, and commercial washrooms without secondary environmental shielding.
Power Installation and Internal Enclosure Sealing
Operational power is provided by 2 x CR2032 lithium coin cell batteries (they are not included), which yield an estimated service life of 18 to 24 months under standard operating duty cycles. When loading or replacing the 2 x CR2032 lithium coin cell batteries (they are not included), technicians must align the dual coin cells according to polarity markings within the inner chassis. Ensure the perimeter gasket seating is inspected and clean of debris before reassembling the double-molded casing to preserve the IPX8 liquid and dust ingress rating.
RF Transmission and Network Coverage Considerations
The unit utilizes 433 MHz frequency band radio frequency data transmission using FSK (Frequency Shift Keying) modulation. An internal 360-degree omnidirectional PCB antenna radiates signals uniformly in all lateral directions, eliminating rotational blind spots regardless of device orientation.
| Operational Parameter | Specification / Recommendation |
|---|
| Transmission Frequency | 433 MHz band (FSK low-power modulation standard) |
| Antenna Profile | Internal 360-degree omnidirectional PCB antenna |
| Open-Field Reach | Up to approximately 100 meters |
| Heavy Industrial / Multistory Reach | Deploy SOLT SR5 series signal repeaters to bypass dense concrete or steel attenuation |
| Visual Confirmation | Integrated indirect dual LED transmission indicator |
System Configuration and Commissioning Workflow
Commissioning involves registering the SB7 cancel call point to central monitoring equipment, including SOLT SM3 series multi-digit display receivers (such as SM3-23PC, SM3-33PC, or SM3-61PC) and SOLT SP series mobile wrist pagers (including SP7-100 and SP5-200). Place the target receiver or wrist pager into setup/programming mode, assign the desired terminal ID or bed/room number, and press the single cancel button on the SB7. The integrated indirect LED lighting flashes upon actuation to confirm wireless transmission. Once registered, test the workflow by triggering a call event on a compatible calling unit and immediately depressing the SB7 cancel button to verify that the active queue entry clears accurately across all paired display receivers and mobile pagers.
