When the SIMA software service was discontinued, remote communication and programming to Spot Devices’ school zones systems was no longer possible; nor was there a means for programming at the pole. For the MODOT (Missouri) Southwest District, ELTEC designed a cost-effective solution while salvaging as many parts as possible. Specifically, the cabinet, battery, charge controller, solar panel, and beacon were reused.
A voltage booster circuit was integrated inside ELTEC’s TC- 18 programmable time clock. The circuit board converts the 5 VDC solar panel and battery to 12 VDC powering the TC-18 time clock and LED. By simply mounting the clock inside the cabinet and connecting four wires, MODOT was back in business.
Every TC-18 is upgradable to become a TC-3000 time clock, an IP/network clock for remote programming and communication. All Spot Devices’ school zone systems have the option of being retrofitted with the TC-3000.
