Intrepid Electronic Systems & TDN Electric Install ERRCS At Design Tech High School

The new Emergency Responder Radio Coverage System (ERRCS) installed by Intrepid Electronic Systems and TDN Electric allows firefighters, police officers or first responders to go inside Design Tech High School while maintaining communications with each other and with dispatch over enhanced radio frequencies. Intrepid Electronic Systems designed and installed the system in the two-story, 63,000 sq. ft building, where the building’s glass and concrete structure was attenuating the radio frequencies. TDN Electric installed the conduit and the terminal boxes. Both the installations were done on a fast-track of four weeks and one week, respectively.

Intrepid Electronic Systems designed three ERRCS antennas for the roof, one for each radio frequency. The donor signals were brought down into the building with separate coaxial cable installed through a two-inch riser of electrical metallic tubing (EMT) conduit wired by TDN Electric. The cables ran to the amplifiers in the first-floor electrical room. TDN Electric then installed the EMT conduit, running on the ceiling space of the first floor and onto the ceiling space of the second floor, and then going up to the roof through a riser.

Intrepid Electronic Systems installed 1500 feet of heliax l/2” coaxial cable to connect the system and provided and installed all amplifiers, along with the secondary power supply, couplers, splitters, and triband antenna. They commissioned and optimized the amplifiers for final operation. The amplifiers boost the strength of the existing radio signal and push it to the 12 antenna placed within the building.
