# Detail or Installation Mismatch in Division 28 Electronic Safety and Security submittals

> Source: https://deviationcheck.com/divisions/28-electronic-safety-security/detail-installation-mismatch/

The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require.

## What to look for in Division 28 Electronic Safety and Security

- **Detector spacing** exceeds NFPA 72 maximum for ceiling height and type
- **Notification appliance placement** does not meet NFPA 72 visible/audible coverage requirements
- **Conductor size** (gauge) or type differs from spec (fire alarm circuits require specific wire: FPLP, FPLR per NEC)
- **Conduit type** mismatch for fire alarm circuits (often requires EMT minimum, some specs require rigid)
- **Pathway survivability level** below spec requirement (Level 2 vs Level 1)
- **Camera mounting height or angle** differs from design
- **Camera lens focal length** does not achieve specified pixels per foot at target distance
- **Card reader mounting height** differs from ADA requirement (48" max per ADA)
- **Door contact type** mismatch (recessed vs surface, wide-gap vs standard)
- **End-of-line resistor value** mismatch with FACP requirements
- **Elevator recall interface** wiring or sequence differs from ASME A17.1/NFPA 72 requirements
- **HVAC shutdown interface** relay location or wiring differs

## Severity

Default grade: Fix and Resubmit. Escalates to Blocker when the difference affects a fire-rated, seismic, or structural assembly.
