Sub-Panel Fire Alarm Riser in AutoCAD for an Elementary School Modernization, California
On a modernization that replaced HVAC, roofing and the fire alarm system together, we produced an AutoCAD riser with a main panel, two sub-panels on data and voice bus, three amplifiers and a remote power supply.
2 sub-panels
on data and voice bus
3 amplifiers
plus a remote power supply
HVAC tie-ins
duct detectors for new units
The challenge
Instead of one big panel, this campus used a main panel and sub-panels in other buildings, linked by data and voice buses. New rooftop HVAC units brought new duct smoke detectors and shutdown interfaces. The riser had to show the bus topology clearly and capture every tie-in to other trades.
What we delivered
- Drew the riser with the main panel, two sub-panels, three amplifiers and the remote power supply, each in its actual room.
- Showed the system bus and voice bus runs between buildings with their cable types.
- Captured the interfaces to HVAC shutdown, beam detectors, kitchen suppression and sprinkler supervision.
- Produced the battery and voltage drop calculations, coordinated with the electrical sheets on the same package.
The result
The riser made a distributed sub-panel system easy to follow and kept the fire alarm interfaces in step with the new HVAC equipment in the DSA package.
