Yagi
Active, Passive, and Hybrid DAS scoped with code-aligned surveys, UL-2524 hardware, isolation verification, and witnessed acceptance.
What you get
AHJ intake: local adoption of IFC 510/NFPA 1225
Required coverage (≥95% general / ≥99% critical)
DAQ threshold (≥3.0)
Test grid density requirements
Hallway/stairwell treatment protocols
Battery hours specification (12–24)
Enclosure NEMA ratings
Alarm points to FACP integration
FCC Part 90 coordination
VHF (150-174 MHz)

700 MHz (763-775 MHz)
800 MHz (806-824 MHz)
900 MHz (896-901 MHz)
AHJ Approved
Designed and executed like an RF acceptance rehearsal. No pricing shown—scope, rigor, and outcomes only.
Pre-Survey Coordination & Site Readiness
AHJ & Code Review (IFC / NFPA requirements, jurisdiction nuances)
Building Plan Review (architectural drawings, floor plans, stairwells, basements, parking)
Test Plan Development (grid spacing, test areas, pass/fail criteria)
Stakeholder Coordination (property management, security, escorts, access times)
Outcome: Survey day runs tight, efficient, and defensible.
On-Site Grid Testing
NFPA/IFC-Compliant Grid Testing
Signal Metrics Collected
DAQ (Delivered Audio Quality)
RSSI
SINR
Per-Floor & Per-Zone Measurements
Pass/Fail Determination by Area
Outcome: Hard data—not opinions—on whether the building meets code.
Donor Signal & RF Environment Assessment
We don’t just test inside the building—we validate what’s feeding it.
Rooftop / Exterior Donor Signal Testing
Carrier Identification & Signal Strength Validation
Interference & Noise Floor Analysis
Line-of-Sight & Mounting Feasibility Review
Outcome: Confirms whether ERCES is even viable—and what system type is required.
Infrastructure & Pathway Assessment
We survey like installers, not just testers.
BDA Location Feasibility
Equipment Room & Power Availability Review
Grounding & Bonding Conditions
Riser & Pathway Identification
Backbone & Antenna Distribution Feasibility
Outcome: Survey data that actually translates into a buildable system.
Photo & Documentation Capture
Everything is documented like it’s going straight into permitting.
Test Point Photos
Equipment Room & Roof Photos
Pathways, Penetrations & Constraints
Annotated Notes for Design & AHJ Review
Outcome: Zero guesswork later for engineers, installers, or inspectors.

Formal ERCES Survey Report
Deficiency Identification
System Recommendation
Design Readiness Summary
AHJ-Ready Documentation
Outcome: A report that supports permitting, budgeting, and enforcement.
