Field impact

What matters on a fire alarm project

  • Greenwich’s ERCES policy is a major preconstruction coordination item. Do not wait until fire alarm acceptance testing to determine whether in-building radio coverage work is required.
  • The posted Fire Marshal fee schedule states a $5 per $1,000 plan-review fee.
  • For projects with access, water-supply, fire-protection, or emergency-communications impacts, review current Fire Marshal conditions early in design.

Pre-submittal

Contractor checklist

  1. Confirm Fire Marshal plan-review fee based on current project construction cost.
  2. Determine early whether the Greenwich ERCES policy applies.
  3. Coordinate any required radio coverage testing/system design separately from the fire alarm scope.
  4. Submit fire alarm/sprinkler plans for Fire Marshal review where applicable.
  5. Confirm final Fire Marshal acceptance requirements before closeout.

Official sources

ERCES is not simply a fire alarm device requirement. It is a separate emergency-responder communications requirement that can affect design, testing, coordination, and project cost.
