Fire sprinkler systems work by detecting heat from a fire, which triggers the release mechanism in the sprinkler head. This opens a valve that allows water to flow through the sprinkler head and onto the fire, helping to control or extinguish it.

The two main types of sprinkler heads are glass bulbs and fusible links. Glass bulbs contain a heat-sensitive liquid that expands and shatters the bulb at a certain temperature, while fusible links use a low-melting alloy that melts to release water.

Fire sprinkler systems have a success rate of over 99% in controlling fires. They can significantly reduce fire-related deaths, injuries, property damage, and environmental impact.

Sprinklers remain on until the fire is extinguished, or the water supply is manually shut off. The duration can range from 30 to 90 minutes, depending on the occupancy hazard classification.

No, fire sprinklers do not detect smoke; they respond to heat. However, they are often used in conjunction with smoke detection systems for comprehensive fire safety.

The sensitivity of fire sprinklers varies based on their installation location. Residential and office sprinklers typically activate at around 68°C, while industrial sprinklers may have higher activation temperatures to prevent false triggers from non-fire-related heat sources.

While rare, accidental activations can occur due to mechanical damage, temperature extremes, vandalism, manufacturing defects, chemical corrosion, or improper maintenance.

Fire sprinkler systems should be inspected annually by a qualified professional, and sprinkler heads should be tested 25 years after installation to ensure proper operation.

Yes, common types include wet pipe systems, dry pipe systems, pre-action systems, and deluge systems, each designed for specific environments and fire risks.
