Sapling SBT 3000 Series Digital TalkBack Clock

The new SBT 3000 Series not only allows a facility to receive the most accurate time possible, but each clock has the capability to report its status back to the master clock. This is done through our TalkBack Technology – each clock can provide its signal strength, its battery life and even information about the segments on the display.

The SBT 3000 Series is a wireless clock system that operates on either Sapling’s 915-928MHz or 2.4GHz (International Use Only) frequency–hopping technology. The digital wireless clocks have the ability to receive and retransmit the signal to neighboring clocks, ensuring an accurate time display throughout a facility.

This series also includes the option to add an Elapsed Timer (3200 or 3300 series only) in order for the digital clocks to conduct a count up or countdown and can easily interface with existing systems.

  • Shatterproof, polycarbonate filters provide a crystal clear display
  • Brightly lit, 7-segment LED displays provides great visibility
  • Extremely durable ABS housing with a two-toned design
