Getting firefighters off the tops of vehicles was a main reason for introducing remote control monitors, but since they first made their appearance on the tops of pumpers and at the tips of aerials, advances in electronics, networking, and new design concepts have turned them into much desired and used pieces of equipment on fire trucks.
Durability and Networking
Eric Combs, vice president of OEM business for Elkhart Brass Company, says Elkhart Brass has two primary focus areas when it comes to remote control monitors. "The first revolves around the robustness, reliability, and durability of the monitor," Combs points out. "Some early-technology electric-mechanical monitors had reliability issues that caused a concern for fire departments when shifting from manual monitors. But through technological advancements, we developed a more robust and rugged product through use of a potting material, basically a liquid plastic, that hardens and encases circuit boards and makes it impossible for water to get in and also helps prevent vibration from cracking the boards."

Elkhart Brass's other primary focus area concerns integrating the monitor with a truck's CANBUS J-1939 system, Combs notes. "In the past you had to open up the unit and get to the circuit board to change settings," he says. "Now we do it through communications where we can change the stow position, flow rate, oscillation, or anything else and even download diagnostics. You never need to touch the circuit board anymore."
Elkhart Brass makes the EXM line of remote control monitors, all of which use the same controller program and the design feature of potting the circuit board, Combs says. The Sidewinder EXM is a bumper turret monitor ranging from 15 to 750 gallons per minute (gpm), the Cobra EXM runs from 500 to 1,500 gpm, the Scorpion EXM from 1,250 to 2,500 gpm, the newly launched SkyStream EXM at 3,000 gpm, and the Sidewinder EXM UHP ultra-high pressure monitor up to 300 gpm at 1,500 pounds per square inch (psi).
Jeff Benson, global product manager for Akron Brass Company, says the company has been making remote control monitors for more than 15 years and, in the past few years, made changes in their control architecture. "We now use the Universal 2 logic box, which has the advantage of ease of installation for OEMs," Benson says. "It greatly reduced the necessary wiring and introduced networking features that operate through the truck's CANBUS J-1939 communication capabilities."

In remote control versions, Akron Brass makes the 3462 forestry monitor that ranges from 30 to 300 gpm, the 3418 Apollo electric that runs up to 1,250 gpm, and the StreamMaster II in 1,500- and 2,000-gpm versions. "They all use the Onboard control system," Benson points out, "and all have J-1939 connectivity." The forestry monitor typically is used on a bumper turret, he adds, while the Apollo usually is
