This case study looks at Tim Herr and his team at Herr Display Vans out of Steger, Illinois. Herr builds a broad range of vehicles including rapid-response trucks and command vehicles but their main business is building tool trucks. Their customers are distributors of tools for companies like Matco, Cornwell and Mac Tools. These trucks are rolling stores and offices. Their customers demand a lot from them.
The Herr team installs one MASTERCELL, two POWERCELLs, inLINK and the ISIS inTOUCH MAX touch screen in all of their trucks. They purchase their system with harnesses manufactured to specific lengths for their trucks.
The inTOUCH MAX touch screen is the heart of the vehicle. The owner and operator of the truck uses this to control everything from the interior lighting, display lighting, scene lights, overhead fans, the hot water heater, and door locks. The screen also displays the voltage on the batteries so the customer knows when he needs to start the truck’s engine to charge them up again. The screens are also customized with the Herr logo to help promote their brand.
The inTOUCH MAX screen eliminates almost all of the switches in the truck that Herr has to add. This dramatically reduces the time that it takes to wire the truck plus it saves a significant amount of space.
Depending on the truck body that the customer specifies, they mount the front and rear POWERCELL in locations that reduce the length of wire running to the functions.
By adding the inLINK wireless module to their system, Herr gets all of the security, immobilizer and alarm functions that they were getting from their old supplier. The big difference is that all of this is integrated into ISIS and this requires no additional wiring. When the customer locks the truck from the ISIS inLINK keyfob, the front POWERCELL engages a solenoid that disables the start circuit on the truck. At the same time, the MASTERCELL monitors inputs tied to switches on the doors and hood plus a motion sensor. If any of these inputs are tripped while security is activated on the ISIS system, an output on the front POWERCELL energizes the siren to alert the owner that someone may be trying to break into the truck. Considering the value of the tools in the back of these trucks, these features help to protect their customers’ investments in inventory.
The ISIS inLINK upgrade also gives Herr’s customers the ability to lock and unlock the doors plus control the lighting remotely from the key fob. This is a feature that they couldn’t implement before with their existing alarm system.
What they save in each truck:
• Individually wired switch panels
• Remote fuse and relay panels
• Aftermarket security & immobilizer systems
• External voltage displays
• Reduction in wiring time
What they gain with ISIS in their trucks:
• A universal wiring system that works on any of the truck bodies that a customer may order
• A unique touch screen interface that sets their trucks apart from their competition
• More robust security, immobilizer and alarm functions
• Wireless control of truck functions
• Diagnostic capabilities for troubleshooting
• The flexibility to add other functions easily and quickly
