4.4 Heat detector
The heat detector HI110 can recognize sharp increases in temperature and is
suitable for areas with a stable ambient temperature.
The heat detector HI112 responds when the temperature exceeds a preset
threshold value.
Heat detectors are used in environments where misleading sources of false alarms
are present and where, if smoke detectors were to be used, an unacceptable
number of false alarms would be triggered.
4.4.1 Parameter sets
The heat detectors HI110 and HI112 have the following parameter sets:
HI110
l 'A1R'
HI112
l 'A2S'
l 'B'
Explanation of designation 'A'
l 'A' parameter sets should be applied at an ambient temperature of
approximately 25 ℃. However, they can be applied at temperatures up to 50
°C. The static response temperature is 60 °C.
Explanation of designation 'B'
l 'B' parameter sets should be applied at an ambient temperature of
approximately 40 ℃. However, they can be applied at temperatures up to 65
°C. The static response temperature is 80°C.
Explanation of designations 'R' and 'S'
l In comparison to the 'S' parameter sets, 'R' parameter sets also trigger alarms
in the event of a temperature increase (e.g., from 20° C to 50 °C within a few
minutes).
