RESSAC technician responded to a call from a clothing retailer in the Northridge Mall in Salinas, CA. Tech needed to resolve a power usage issue between the lighting and the EMS system. He found that the emergency lighting override switch was in the ON position. Troubleshooted with T-Wave, found connections not communicating via the controller. Switching wiring from U17 to &18, cycled the emergency override to auto and restored communication. Will need to return to replace a faulty controller, but lighting issue should be resolved now.
