Draft curtains positively impact sprinkler operation by preventing the rapid spread of smoke and heat. This containment helps maintain a lower ceiling temperature, allowing sprinkler systems to activate more effectively and at the appropriate time. The presence of draft curtains ensures that sprinkler heads are not overwhelmed by high heat or smoke, facilitating a more targeted and efficient firefighting response.

• Coordination with detection systems

The integration of draft curtains with fire detection systems is essential for a cohesive fire safety strategy. Draft curtains are designed to complement the detection systems by ensuring that once a fire is detected, the spread of smoke and heat is controlled, allowing for accurate activation of sprinklers. This coordination is crucial for the timely deployment of both passive and active fire protection measures, enhancing overall building safety.

• Sprinkler system design considerations

When incorporating draft curtains into a building’s fire protection plan, several design considerations for the sprinkler system must be taken into account. These include ensuring that the layout of sprinkler heads remains unobstructed by the curtains and that the sprinkler system’s water distribution is not hindered. Proper alignment between draft curtains and sprinkler heads is vital to avoid any reduction in the effectiveness of fire suppression capabilities, necessitating careful planning and coordination during the design phase.
