...I am required to install a heat detector in the attic,because there is a gas-fed furnace/air handler up there,..and there are no gable fans,just vents...My supply house carries BRK,and sells a rate of rise detector thats compatible with the a/c-battery back-up smokes,but for only up to 135 degrees F...An attic could easily attain this temperature on a sweltering summer day.Then it'll set the whole system off with false alarms,...if I "kit-bash" and use another brand of heat detector that has a higher temperature,I void the UL listing on the device.What should I do???
