1. Geometry

Ceiling height (m) Smoke reservoir area (m²)

Fire location Small compartmentUnder A.1 of UNE 23585:2017, its largest dimension is at most five times the design fire diameter and air can enter from only one direction.

2. Sprinklers Sprinklers presentSprinkler response

Response affects fire models that distinguish fast and normal response. If unknown, the more conservative model is adopted.

Activation temperature (°C) Design operating area (m²)

3. Design fire Fire model Storage present

Fire area (m²) Fire perimeter (m) Lower HRRPUA (kW/m²) Upper HRRPUA (kW/m²)

4. Design objective

Recommended minimum height: 2.5 m (initial criterion for use · Table 2).

Specify a height freely, overriding the minimum for use or storage

Mandatory range: 1.35–12.15 m (1/10–9/10 of ceiling height). Always checked, including when specifying a height freely.

Design criterionSmoke-free height (m)Height from the floor to the base of the smoke layer.

5. Ventilation SystemVent diameter (m) Vent at ceiling level

Layer depth below the vent: 11.00 m (ceiling height − vent offset − smoke-free height).

Is the vent close to a wall?Select the vent position to evaluate plug-holing (E.9 / E.10).
