Abstract
A combination fire alarm/air conditioner, which can immediately detect a fire. The device includes a temperature-sensor and/or a smoke-sensor installed in the room-side air inlet of the air conditioner. Signals generated by the sensor are received by a microcomputer which monitors them based on a threshold and a rate of change of the signals. When the rate of change of the signals exceeds the threshold, the microcomputer produces signals which set off an alarm.
