# Performance Specification Gap in Division 28 Electronic Safety and Security submittals

> Source: https://deviationcheck.com/divisions/28-electronic-safety-security/performance-specification-gap/

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

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

Key performance parameters in Div 28 submittals:
- **Fire alarm system type** (conventional vs addressable, single-stage vs two-stage)
- **Notification appliance candela rating** (15, 30, 75, 110, 135, 185 cd per NFPA 72 Table 18.5.4.3.1)
- **Notification appliance dBA rating** (minimum 15 dBA above ambient or 5 dBA above max, per NFPA 72)
- **Smoke detector sensitivity range** (per NFPA 72, UL 268, typically 0.5-4.0 %/ft obscuration)
- **Duct detector air velocity range** (fpm per NFPA 72/90A)
- **System capacity** (number of addressable points, zones, loops for FACP)
- **Camera resolution** (megapixels, pixels per foot at target distance)
- **Camera frame rate** (fps at stated resolution)
- **Camera low-light performance** (minimum illumination in lux)
- **Camera storage retention** (days at stated resolution and frame rate)
- **Access control panel capacity** (doors, readers, cardholders per panel/server)
- **Card reader technology** (proximity 125kHz, smart card 13.56MHz, mobile credential, biometric)
- **Battery standby time** (24 hours for fire alarm per NFPA 72, longer for some security systems)
- **Pathway survivability** (Level 0, 1, 2, 3 per NFPA 72 Chapter 12)

## Severity

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.
