Fire Alarm Riser and Battery Calculations in AutoCAD for an Elementary School Campus, California
For a campus-wide fire alarm replacement, we produced two riser sheets in AutoCAD for a voice evacuation panel running ten signaling line loops, along with the battery and voltage drop calculation sheets.
10 SLC loops
on one voice evacuation panel
2 riser sheets
plus battery and voltage drop
8 cable types
including underground fiber
The challenge
Replacing a deteriorated system across a whole campus means one panel feeding many buildings. The riser had to show every loop, every amplifier and power supply pair, how they connect across the site, and which cable goes where, so the contractor could price and build it.
What we delivered
- Drew two riser sheets showing the panel, voice command, ten signaling line loops and the amplifier and power supply pairs they feed.
- Built the cable legend with eight cable types, from detection pairs to fiber and remote annunciator bus.
- Showed the remote microphone, annunciator, cellular communicator and a spare loop card for future use.
- Produced the battery and voltage drop calculation sheets for visual and audible circuits.
- Picked up multiple rounds of redlines in quick turns.
The result
The riser and calculation sheets went into the DSA set in agreement with the floor plans after every redline round.
