Low Voltage
Fire alarm, security, AV, data — one takeoff.
OmniTakeoff separates Division 27 (communications) from Division 28 (life safety) so each system gets its own scope, its own price, and its own evidence trail.

What the takeoff produces
A low voltage takeoff that survives review.
Every line item carries the source it came from — sheet, detail, and spec paragraph — so the senior estimator can audit in minutes, not hours.
- Fire alarm devices (smoke, heat, strobe, pull) counted by zone
- Security cameras, access-control readers, and intrusion sensors enumerated
- AV scope (displays, racks, speakers, mics) extracted by room
- Data drops counted with cable category and termination class
- Headend equipment (NVR, panel, head-end racks) flagged for datasheets
Low Voltage features
Built for the way your office actually bids.
Per-system separation
Fire-alarm, security, AV, and data each report as their own takeoff with their own labor units and acceptance criteria.
Riser / one-line awareness
Risers and one-lines are graph-walked, not treated as flat plans, so backbone cable lengths are calibrated, not extrapolated.
Spec-paragraph linking
Each device row links back to the spec section that called it out, including the NFPA / TIA / EIA edition referenced.
Headend datasheet prompts
FACP, NVR, and AV racks prompt for the manufacturer datasheet so accessories and labor are correct.
Frequently asked
Questions we hear from estimators.
- Do you split Division 27 from Division 28?
- Yes — they ship as separate scopes with separate labor and acceptance criteria.
- Can I bid voice/data as a flat per-drop or detailed?
- Either. The drop assembly is editable; switch from 'per-drop' to 'cable+jack+plate' line items with a single toggle.
