🔥 Understanding Line Type Heat Detection
Line type heat detection systems are essential components in modern fire alarm designs, offering continuous monitoring along their entire length. These systems are particularly valuable in environments where traditional point detectors may not be practical or effective.
📍 Key Applications and Use Cases
- Underground parking facilities
- Loading docks and warehouses
- Tunnels and confined spaces
- Industrial facilities
- Cable trays and utility corridors
🌡️ Operating Principles and Detection Parameters
Line type heat detectors operate based on two main principles:

When implementing line type heat detection, several key factors must be considered to ensure system effectiveness and reliability:
- Maximum monitoring distance: Up to 328 feet (100 meters) per sensing line - Exceeding this limit can result in reduced sensitivity and delayed fire detection
- Mounting height: Typically 7-30 feet (2-9 meters) from floor level - Incorrect height placement can lead to missed detections or false alarms due to stratification of heat
- Temperature ratings: Available from 135°F (57°C) to 185°F (85°C) - Selecting inappropriate temperature ratings may cause system failure to detect fires or trigger unnecessary evacuations
- Environmental conditions: Consider ambient temperature fluctuations, as extreme variations can affect detector performance and lead to system malfunctions or false alarms
