Fire Alarm Takeoff Services — CSI Division 28 Estimating
Fire alarm systems are a critical scope item in virtually every commercial and institutional construction project. Accurate fire alarm takeoffs require specialized knowledge of NFPA 72 requirements, device spacing rules, and notification appliance circuits.
Apex Electric Estimating Inc provides fire alarm takeoff services that deliver accurate material quantities, labor estimates, and bid-ready packages for contractors bidding fire alarm scope.

Why Fire Alarm Takeoff Estimating Is Specialized
Fire alarm systems have unique requirements that differ from power and lighting scope:
- NFPA 72 compliance: Device spacing, placement rules, and notification appliance requirements governed by NFPA 72
- Addressable device counting: Each device on the addressable loop must be individually counted and programmed
- Notification appliance circuits (NAC): Voltage drop calculations and circuit loading requirements
- Wiring methods: Fire-rated cable requirements (FPL, FPLR, FPLP) and survivability considerations
- Integration requirements: Interface with HVAC, elevator, door holder, and suppression systems
- Code jurisdiction: Local AHJ requirements that may exceed minimum NFPA standards
Our estimators understand these requirements and deliver takeoffs that account for every device and foot of fire-rated cable.

- Kitchen suppression system interfaces
Fire Alarm Estimating Methodology
1. Drawing and Specification Review
We review architectural reflected ceiling plans, electrical drawings, and fire alarm specifications to understand device types, spacing requirements, and system architecture.
2. Device Takeoff
We count every initiating device and notification appliance from the reflected ceiling plans, applying NFPA 72 spacing rules to identify any missing devices.
3. Wiring Measurement
We measure every fire alarm cable run from the control panel to each device location, accounting for home runs, T-taps, and circuit routing.
4. Panel and Circuit Scheduling
We develop panel schedules showing device counts per circuit, NAC circuit loading, and battery calculations.
5. Bid Package Assembly
You receive a complete bid package: editable Excel spreadsheet, color-coded marked-up plans, PDF summary, and basis-of-estimate notes.

Frequently Asked Questions
Q: Do you estimate for voice evacuation systems? A: Yes. We estimate for voice evacuation and mass notification systems, including speaker-strobes, digital voice command equipment, and emergency communication systems per NFPA 72 Chapter 24.
Q: Can you estimate for high-ceiling applications? A: Yes. We account for beam detectors, air-sampling systems, and specialized detection used in high-ceiling applications (warehouses, atriums, auditoriums) where standard spot detectors are not suitable.
Q: Do you provide voltage drop calculations for NAC circuits? A: Yes. We calculate voltage drop for notification appliance circuits and flag circuits that exceed manufacturer or code limits.
Q: How long does a fire alarm takeoff take? A: Standard turnaround is 24 hours for most fire alarm takeoffs. Large multi-building systems may require 48 hours.
