Signaling Systems
Heat Detectors
Fixed temperature, spot-type:
- Used in closed areas (rooms, closets, etc.), primarily for property protection. Not considered an early warning device.
Rate of rise, spot-type:
- Enclosed areas (rooms, closets, etc.); primarily used for property protection where design goals require more sensitive heat detection and response to developing fires. Avoid use in areas of fluctuating ambient temperature. Not considered an early warning device.
Rate compensation :
- Same as for fixed temperature, spot-type heat detectors. Because of sealed design, may be used in dusty and moist areas. Spacing ratings are better due to reduced thermal lag.
Fixed temperature, line-type:
- Application is similar to spot-type. Is used in severe environments, cable trays, wharf applications, and historic buildings.
