Who should use this manual

This manual is for fire alarm commissioning engineers deploying IntelliKnight 5820XL or 5820XL-EVS panels. The EVS variant requires voice evacuation system competence in addition to fire detection programming.

5820XL vs 5820XL-EVS

The standard 5820XL provides fire detection and conventional sounder/beacon NAC outputs. The 5820XL-EVS adds an integrated Emergency Voice System amplifier for voice evacuation announcements — required for high-occupancy buildings under NFPA 72 and many local codes. The EVS variant is a single-cabinet solution that simplifies large commercial installations needing both fire detection and voice evac.
