Fire Station upgrade package for Chicago suburb

TEMPE, AZ - 06/06/2012 - STC has furnished a full replacement control package to Bloomingdale, IL to replace an old Right-Of-Way (ROW) hybrid fire station signal which was no longer functional.

The village of Bloomingdale had a fire station that was set back some distance from the nearby arterial. As the truck drove down the driveway towards the arterial, the system would activate optically and turn on the signals. For years the system did not work and there seemed to be no way to fix it since ROW went out of business in 2002.

STC was called in to provide a similar system, one that would work with a GTT Opticom detector package. STC furnished a solar-powered master unit and a solar-powered slave unit placed at the end of the fire station driveway with indications facing the traffic on the arterial. The design is based on the hybrid systems STC has furnished to the City of Tucson over the last 10 years and is approved for use in the MUTCD.

The master unit consists of a suitably-sized solar power system on a mast arm pole. The master also includes an Opticom 721 detector assembly with a euro-style card rack and 752 phase selector card (E series for 24VDC operation). Since the solar power system is a nominal 12VDC, a DC-DC converter was included to run the Opticom equipment. Once triggered, the control logic for the master would run through the timing cycles for the lamp sequence and radio across the street to the slave unit to run the LED lamps in a like manner. The control logic includes an LCD screen so the user can easily adjust the run time values for each interval.

The slave included a solar power system as well, and was linked to the master via license-free radio. Both the master and slave were configured with high efficiency red and amber DC LED lamps also from STC. The equipment was furnished to STC's Midwest distributor Traffic Control Corporation and the work was done by Meade Electric.
