It should be be considered for use if there is a danger of nuisance alarms from smoke detectors.
Rate of Rise detectors have a fixed upper limit, but they also measure the rate of increase in temperature.
A Rate-of Rise detector is to be preferred to a static heat detector unless sharp increases in temperature
are part of the normal environment in the area protected by the heat detector i.e kitchens.
