Wally `Larman installed a fire alarm system for a single-story commercial account that included smoke/duct detectors, manual pull stations, HVAC shutdown, a remote annunciator, and horns/strobes. Wally carefully selected the appropriate number and type of devices, calculated the correct AWG size for all cables based upon the manufacturer’s instructions and filed for the work. After receiving approval for his plans, Wally ran the cables for the devices in the air plenum above the drop ceiling, occasionally tie-wrapping them to the ceiling grid. When the installation was completed, Wally tested each device and all seemed to be in order, but when the job was inspected, the inspector and customer were not happy. Can you determine what Wally did wrong and what he must do to satisfy the inspector and customer? 485 Bus Why is Inspector Unhappy?
