One-Sheet Fire Alarm Riser in AutoCAD for a High School Campus, California

For a high school fire alarm replacement, we fit the whole campus riser on one AutoCAD sheet, with a single companion sheet for battery and voltage drop calculations.

The challenge

Not every campus needs a multi-sheet riser. Here the goal was to show the full system for five buildings and a portable on one sheet without losing clarity.

What we delivered

  • Laid out the panel, voice command, ten signaling line loops and amplifier and power supply pairs on one riser sheet.
  • Added the cable legend, remote microphone, annunciator and communicator connections.
  • Produced the battery and voltage drop calculation sheet for visual and audible circuits.
  • Picked up the client’s redlines and reissued.

The result

One riser sheet and one calculation sheet covered the whole campus, keeping the set compact and easy to review.
